F60 Cooling
Protection for the liquid-cooled units. An external sensor is connected to the drive (DI: Cooling
Monitor) to indicate if cooling liquid is circulating. If the drive is in STOP state, only a warning is
issued. In RUN state a fault is issued and the drive makes a coast stop.
Possible cause:
- The cooling circulation of a liquid-cooled drive has failed.
Correcting measures:
Check reason for cooling failure from the external system.
-
F62 Run Disabled
A Run Disable warning signal is issued when a Run Enable signal has been removed from the I/O.
F63 Quick stop
Possible cause:
- A command has been given from a digital input or the fieldbus to make a quick stop.
Correcting measures:
- A new run command is accepted after the quick stop is reset.
F64 MCB State Fault
This function monitors the MCB status. Feedback status should correspond to the control signal.
The delay to fault is defined by P2.9.1.13 MCB Fault Delay for A2 and A3. A4 is immediately.
A1: Code given by V084 and older versions.
A2: MCB open while request is to close.
A3: MCB closed while request is to open.
A4: MCB opened externally while AFE unit was in run state.
Possible cause:
- Main circuit breaker has opened while drive controls it to close.
- Main circuit breaker has closed while drive controls it to be open
Correcting measures:
Check the main circuit breaker function.

when the set limits are exceeded. The marine application supports two PT100 boards. One can be
used for the motor winding and the other for the motor bearings.
Possible cause:
- The temperature limit values set for the PT100 board parameters have been exceeded.
- The number of inputs selected is higher than what is actually connected.
- PT100 cable is broken.
