phase wires on the motor or the NI-DV terminal strip. Increase switching frequency. 0 = Auto 1 = Low = 4 kHz 2 = High = 8 kHz Increasing switching frequency increases losses within NI-DV, thus reducing efficiency. NI-DV switching frequency can be changed via OJ-DV Hterm or via Modbus. Use OJ-DV Hterm to view the alarm and determine which alarm has stopped the controller/motor. Reset the alarm by short-circuiting the ”Alarm reset” input – digital input Din1 or Din2 depending on the setup. The alarm can also be reset by disconnecting the power supply to the NI-DV and reconnecting it after approx. 60 seconds. Read out the alarm via Modbus registers and determine which alarm has stopped the controller/motor. Remedy the cause of repeated alarm activation.
