Functions
Motor Overload Protection
Electronic thermal overload relay
Instantaneous Overcurrent
Motor coasts to a stop at approximately 180% rated current
Fuse Blown Protection
Motor coasts to a stop by blown fuse.
Overload
Motor coasts to a stop after 60 sec. of a 120% overload condition.
Overvoltage
Motor coasts to a stop if drive DC bus voltage exceeds 1050VDC.
Undervoltage
Motor coasts to a stop if drive DC bus voltage drops to
546 VDC or below.
Momentary Power Failure
Factory setting provides for motor to coast to a stop after
momentary power failure of more than 15 ms. Can be
reprogrammed to allow continuous operation (ride-through)
during power failure of up to 2 seconds or longer.
Heatsink Overheat
Thermoswitch
Stall Prevention
Stall prevention at acceleration /deceleration and constant
speed operation.
Ground Fault
Provided by electronic circuit.
Power Charge Indication
"CHARGE" lamp remains lit until bus voltage drops below 50 V.
