Resetting a Trip Condition
Before a trip can be reset, the trip condition must be removed.
NOTE
A Heatsink Over-temperature trip may not reset immediately. The unit needs time to cool sufficiently.
Local Mode
To reset a trip in Local Mode:
Remove the trip condition
Press the Stop key to clear the trip. You can now press Run to restart the
system.
Remote Mode
To reset a trip in Remote Mode:
Remove the trip condition
Press the Stop key to clear the trip. You can now press Run to restart the
system.
Remove the trip condition
-
Alternatively, remove and re-apply the 24V supply at X01, or toggle the
ENABLE to 0V and then 24V to restart the system.
More than one trip can be active at any time. For example, it is possible for both the HEATSINK and the OVERVOLTAGE
trips to be active. Alternatively it is possible for the drive to trip due to an OVERCURRENT error and then for the
HEATSINK trip to become active after the drive has stopped (this may occur due to the thermal time constant of the
heatsink).
NOTE
Motor over temperature sensing is required where the motor has a full-load Ampere rating of less than 50% of the
drive output rating; or when the MOTOR STALLED trip is TRUE (TRIPS STATUS::DISABLE TRIPS>>MOTOR
STALLED); or when the STALL TIME parameter is increased above 480 seconds. Motors used in conjunction with
the drive controller shall be provided with PTC sensor(s) or relays suitable for use with the variable speed drive.
Technical details can be found in Chapter 3 Installing the Drive.
