NI-DV has built-in current limitation for the protection of motor and cablesand cannot therefore supply more current than it is set to. In the event of lacking phase on the supply input, NI-DV will reduce speed and activate a noncritical alarm.The NI-DV motor output terminals are short-circuit protected against phase-to-phase short circuiting.The NI-DV motor output terminals are short-circuit protected against phase-to-phase short circuiting.DE-23/365.7. AlarmsNI-DV has a built-in alarm monitor, which monitors optimal fault-free operation and triggers an alarm if operating or performance problems are observed.Alarms are either ”Critical” alarms or ”Non-critical” alarms. • ”Critical” alarms stop the motor. • ”Non-critical” alarms reduce motor performance. o The built-in alarm monitor stops the NI-DV. o If the alarm situation passes, the alarm is automatically reset and NI-DV restarted. o If the maximum number of restarts (5 times/60 min) is exceeded,
