Cables must not be connected or disconnected, nor signal tests carried out, while the power is switched on. The Varispeed L7 DC bus capacitor remains charged even after the power has been switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out maintenance.
Page 9
The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power. It is therefore necessary to wait for this time before opening its covers. All of the main circuit terminals may still carry dangerous voltages.

The inverter measures the current level or torque reference S2-05 sec. after the speed-agree condition (acceler- ation finished) for the time set in S2-06 and calculates the average value to estimate the load. This value is used for the calculation of slip which is added to the speed reference at leveling speed (see 6.14).

To prevent a sudden and unexpected stop of the inverter due to an over temperature, an overheat pre-alarm can be output. The temperature level for that pre-alarm can be set in parameter L8-02. Using parameter L8-03 the inverter operation when an over temperature occurs can be selected.
Page 199: Output Open Phase Detection, Ground Fault Detection
This function detects the earth leakage current by calculating the sum of the three output currents. Normally it should be 0. If the earth leakage current gets too high, the inverter output is switched off and a GF fault is shown on the display.
Page 200: Cooling Fan Control, Setting The Ambient Temperature
Using parameter L8-10 two modes can be selected: 0: The fan is ON only when the inverter output is ON, i.e. a voltage is output. This is the factory setting. The turn OFF delay time for the fan can be set in parameter L8-11. After a stop command the inverter waits for this time before switching OFF the cooling fan.
Page 201: Input Terminal Functions, Disable The Inverter Output (baseblock)
When hardware baseblock is activated, the power supply of the IGBT driver circuit is cut off and the motor starts to coast. To use this baseblock function the digital input S8 must be used. The input is a NC input, i.e. if terminal S8 is open, the inverter is base block condition.
Page 202: Stopping The Inverter On External Device Errors (external Fault Function)
For example, if an external fault signal is input to terminal S3, EF3 will be displayed. To use the external fault function, set one of the values 20 to 2F in one of the parameters H1-01 to H1-05 (dig- ital input terminal S3 to S7 function selection).

Setting Example When the timer function input is ON for longer than b4-01, the timer output function is turned ON. When the timer function input is OFF for longer than b4-02, the timer output function is turned OFF. An example of timer function operation is given in the following diagram.
Page 205: Changing The Pg Direction
Case 4 Changing the PG direction A digital input can be used to change over the PG feedback signal direction. Therefore one of the parameters must be set to 89. The PG direction is clockwise (CW) when the input is open and counterclockwise (CCW) when the input is closed.
Page 206: Motor 2 Selection
(H2- = 1C). If motor 2 is selected, the speed set in d1-19 will be the speed reference. d1-19 has priority over all speed inputs except the service speed input. The output signal sequence (brake control, contactor etc.) is the same as for motor 1.
Page 207: Output Terminal Functions
The output frequency is lower than the zero speed level*. * The Zero Speed Level depends on the control mode. It is 0.1 Hz for Closed Loop Vector, 0.5 Hz for Open Loop Vector and 1.2 Hz for V/f control.

During DC Bus Undervoltage (Setting: 7) If a multifunction output is set to this function, the output is switched ON as long as a DC bus under voltage is detected. During Baseblock (Setting: 8) If a multifunction output is set to this function, the output is switched ON as long as the inverter output is base blocked.

Page 223: Pg Option Cards, Pg Setup
Set the number of PG (Pulse Generator/Encoder) pulses in pulses per revolution. If a PG-F2 card is installed, the encoder type must be set in parameter n8-35 before the PG constant is set. The possible set values for F1-01 depend on the n8-35 setting. The following resolutions can be set:...
Page 224
When the number of gear teeth has been set, the number of motor rotations within the Inverter is calculated using the following formula. No. of motor rotations (r/min.) = No. of input pulses from PG × 60 / F1-01 × F1-13 (No. of gear teeth on PG side) / F1-12 (No. of gear teeth on motor side)

(speed reference and actual motor speed are within the setting range of L4-02) and if a speed deviation higher than the set value in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected, the Inverter stops according to the setting in F1-04.
Page 226: Machine Data Copy Function
EnDat encoder is used, the motor and encoder data can be saved in the encoder memory and can be read out later, e.g. if a motor has been replaced to an equal type or if the inverter is replaced.
Page 227
Verify Saved Parameters To compare the parameters stored in the inverter and encoder the parameter F1-23 must be set to 3 ("EVRFY, DATA VERIFYING" is displayed during the verify process). If the data are identically, the display will show "EVRFY, VERIFY COMPLETE".
Page 228: Rescue System
Rescue System Using rescue operation the car can be moved to the next floor if the power supply fails. In this case the inverter must be supplied by a UPS or a battery and the rescue operation must be enabled by a digital input (H1- 85).
Page 229
A must be opened, before B is closed. If the UPS power is weak or Light load detection is not used, it can happen that the inverter trips with a UV2 fault. In this case increase the UPS power, use the light load detection function or use the configuration in example 2.
Page 230
The contactors must be operated, so that contactor B is always opened, before A and C are closed. Contactor C can be closed after A but not before. When the rescue operation is disabled, the contactors A and C must be opened, before B is closed.
Page 231
Depending on the rescue system it might be useful to apply a torque limit. The torque limit for rescue opera- tion can be set in parameter S3-11. It is active only if the rescue operation digital input is set an has no effect to the normal operation.
Page 232: Automatic Fault Reset
Working Principle Whenever a fault occurs, the inverter output is cut and the brake is closed. A fault is output. When the auto- matic fault reset is enabled, the fault is reset 2 seconds after the Up/Down signal has been removed. The inverter can be restarted.
Page 233
Fault Restart Indication When the fault retry function is used, the inverter tries to reset the fault every 5 ms. If a digital output is pro- grammed for the "Restart enable" function (H2- =1E), the output is set as long as the inverter tries to reset the fault.

The following causes are possible: The Inverter is operating (drive mode). There are some parameters that cannot be set during operation. Turn off the RUN command and then set the parameters. Passwords do not match. (Only when a password is set.) If the parameter A1-04 (Password) and A1-05 (Password Setting) settings are different, the parameters for the initialize mode cannot be changed.
Page 264: If The Motor Does Not Operate Properly
The load is too heavy Check the motor current. If it is at the limit of the inverter rated current the load might be too high. Check the inverter size and the mechanical system. Check also if the brake is working or not to make sure, that the motor is not running against the closed brake.
Page 265: If Motor Deceleration Is Slow, Motor Torque Is Insufficient, If The Motor Overheats
The torque limit has been reached. When a torque limit is reached (L7-01 to L7-04), the motor torque will be limited. This can lengthen the decel- eration time. Check the L7- parameters to be sure that the torque limit values are suitable.

Originally written on RotoAsk | Last updated 10/21/14
Start 'em: (CAR) Cam Newton vs. (SD) – Newton has been amazing for fantasy owners lately including scoring three touchdowns in week fourteen in a win over the Falcons, and should be able do something similar this coming weekend against the Chargers. The Chargers just allowed Big Ben, returning from substantial injuries to throw for almost 300 yards and three touchdowns; I am expecting Newton to account for another three touchdowns in week fifteen. Freeman put up 420 yards and three touchdowns when he faced the Saints earlier this season (TB) Josh Freeman vs. (NO) – With less than 200 yards and two touchdowns last week against the struggling Eagles secondary, Freeman was quite the disappointment for those who started him, but should be much better against the Saints. The Saints were just ripped by Eli Manning and the Giants for four touchdowns and Freeman did put up 420 yards and three touchdowns against them earlier this season. (KC) Jamaal Charles vs. (OAK) – Charles would have left week fourteen after the first couple plays and still satisfied fantasy owners as he took the a handoff on the opening possession 80 yards for a touchdown. Before the game was over he had doubled his yardage to finish with 165 total yards. He only has four touchdowns on the season but is amassing tons of yards; against the Raiders, one of the worst teams in the NFL at the moment Charles might be able to replicate the performance. (BUF) C.J. Spiller vs. (SEA) – Fred Jackson has been confirmed as out for the season so it will be Spiller getting a full workload the rest of the season, and with such a dynamic skill set is a must start the rest of way despite his matchup. Spiller is easily the best offensive weapon the Bills have and they would be wise to use him as much as possible. Brown may have left a sour taste in fantasy owners mouths, but should still be started the rest of the way (PHI) Bryce Brown vs. (CIN) – Brown was a massive bust for fantasy owners last week after being a fantasy gold mine the two weeks prior; don't give up on him yet though. Brown has very nice matchups against the Bengals, Redskins and Giants over the final three weeks and with LeSean McCoy unlikely to play again this season should see healthy workloads in each game. (SD) Danario Alexander vs. (TB) – After watching Danario score a pair of beauty touchdowns this past weekend against the Steelers, I won't even be thinking of taking him out of my lineup the rest of the way. I had the pleasure of picking him up in several leagues and reaped the rewards once again in week fourteen and am expecting more in week fifteen against the Buccaneers secondary. Gordon is coming off a season high 12 targets and has a great matchup against the Redskins (CLE) Josh Gordon vs. (WAS) – Despite only 86 yards last week Gordon saw a season high 12 targets, which bodes very well for anyone who want s to employ him in the next week or so. Against the Redskins Gordon has the potential for another 100-yard game with a score like he had just two weeks ago. (TB) Mike Williams vs. (NO) – Vincent Jackson is a must start nearly every week and should be able to tear it up against the Saints, but don't forget about Mike Williams whom has touchdowns in back-to-back weeks and seven on the season. I am not expecting a homerun effort from Williams but I do think he can reel in 5 catches for 60 yards and a score. (BAL) Dennis Pitta vs. (DEN) – Pitta is never a slam dunk as he is yet to have a back-to-back touchdown games this season and has a yardage high of 73, but he still has a very nice matchup against the Broncos this coming Sunday and could help out the many fantasy owners out there struggling to find a good tight end each week. Sit 'em: (DAL) Tony Romo vs. (PIT) – Last week I suggested sitting Rivers against the Steelers, a decision that proved to be wrong as he threw three touchdowns, but I am still very hesitant about Tony Romo in week fifteen. Not only are the Steelers a very tough defense, but also Dez Bryant might not be able to play due to a finger injury. Early reports stated Dez was possibly done for the season while newer ones state that Dez thinks he will play (athletes always say that). Even if Bryant does play how effective will he be with a seriously injured hand? This is shaping up to be a very tough game for Romo. RGIII was helped off the field last weekend and might not be able to help your fantasy team in week fifteen. (WAS) Robert Griffin III vs. (CLE) – At the moment it is not even sure if RGIII will be able to play come Sunday against the browns after suffering a knee sprain in an exciting week fourteen win over the Ravens. While he will likely be the talk of the football world, it should be an open and shut close in the fantasy world; sit him. Much of Griffin's effectiveness comes from his mobility and ability to run, a sprained knee might affect him there. Also, the Browns are terrible against the run so the Redskins should be able to find success running the ball. Finally, I would not be surprised if he was straight up unable to play or sat by the coach. Gore has another 1000-yard season under his belt but will be hard pressed to add many more yards against the Patriots. (SF) Frank Gore vs. (NE) – Back to back touchdown games and another 1000-yards season under the belt for one of my favorite running back Gore; congratulations! Now that is out of the way, time to get on the bench… The Patriots have been one of the best teams in fantasy against running backs, a mix of their improved defense and stellar offense that keeps other teams throwing to keep up. Despite Gore's impressive play in 2012 I am not expecting much from him on Sunday. (DET) Mikel Leshoure vs. (ARZ) – While he does have close to 700 yards rushing to go along with his seven touchdowns over his eleven games this season, I have some worries about Leshoure this coming weekend. First off, his 3.7 yards per carry is rather weak, while three of his seven touchdowns came in one game. This coming weekend he plays a terrible team with a decent defense in the Cardinals, and while not a terrible matchup obviously, I just think Leshoure has been a little underwhelming on the field and might struggle to gain yards (again, 3.7 ypc). (CAR) DeAngelo Williams vs. (SD) – With over 100 total yards and a touchdown last week in the Panthers win over the Falcons, Williams was a nice play for small amount of owners who started him and might be a popular waiver add through the week. While he might be worth the waiver pick up I am not looking to add him to my starting line up. The Chargers do have a banged up defense at the moment but are still better against the run than the pass; I see Cam Newton doing most of the damage in this one while Williams is left with a stat line closer to 12 carries for 50-60 yards. (TEN) Kenny Britt vs. (NYJ) – Even without Darrelle Revis the New York Jets are winning games lately and it can still be credited to the play of the defense. Cromartie has proved himself to be a shutdown corner at times, using his big body to disrupt the opposing teams top wide out. For the Titans that wide out is Kenny Britt, who is coming off his first 100-yard game of the season. I expect Britt to end up below 100 again without a touchdown in against the Jets. I would seriously consider sitting Johnson against a stellar Seahawks secondary (BUF) Stevie Johnson vs. (SEA) – The Seahawks have one of the best secondary units in the league and Johnson can't seem to grab a touchdown while getting good yardage at the same time. Since the first three weeks of the season when Johnson scored 11, 11, and 12 points respectively, he has only broken double-digits twice. I would not be looking for Johnson even meet those numbers against the Seahawks. (IND) T.Y. Hilton vs. (HOU) – The Houston have struggled against the pass a bit lately, and have been decimated twice by elite quarterbacks (Rodgers, Brady), but Luck is not an elite quarterback yet; case in point, last week. Luck was only able to throw one touchdown with two interceptions against the Titans last week and won't be given an inch against a divisional opponent that is coming off an embarrassing loss and trying to secure the #1 seed in the conference. (PIT) Antonio Brown vs. (DAL) – Brown had one of the rare touchdowns of his career last week against the Chargers, catching a 1-yard pass from Roethlisberger in the fourth quarter. Despite the touchdown, Brown still did not surpass ten fantasy points, something he has only done ONCE this season. Do not start Brown this week unless you are happy with what he has been giving you until this point. (DET) Brandon Pettigrew vs. (ARZ) – I had trouble finding a tight end that struck me as someone people might want to avoid, so instead I will just remind people that Lions TE Brandon Pettigrew injured his ankle last weekend and is unlikely to play against the Cardinals. Make sure you find a replacement if you have been starting Pettigrew.
