Code Description Comments
2-041 M1 Overcurrent The power module has detected that the amperage to the associated motor
is beyond the limits of the power module. Possible causes for this could be
short circuit or locked motor rotor.
2-042 M2 Overcurrent
2-043 M3 Overcurrent
2-044 M4 Overcurrent
2-045 M5 Overcurrent
2-046 M6 Overcurrent
2-047 M7 Overcurrent
2-048 M10 Overcurrent
2-051 M1 Mosfet Short
The power module has detected that the output switching transistor for
the respective motor is not switching off when expected. If the condition
persists, the likely cause is that the power module has failed and needs
replacement.
2-052 M2 Mosfet Short
2-053 M3 Mosfet Short
2-054 M4 Mosfet Short
2-055 M5 Mosfet Short
2-056 M6 Mosfet Short
2-057 M7 Mosfet Short
2-058 M10 Mosfet Short
2-061 M1 Current Sensor
The power module has detected unexpected results for the applicable
output current sensor. If the motor appears to be operating correctly, the
power module may be damaged.
2-062 M2 Current Sensor
2-063 M3 Current Sensor
2-064 M4 Current Sensor
2-065 M5 Current Sensor
2-066 OverTemp Cutoff
Internal temperature exceeds Cutoff Temperature
2-067 UnderTemp Cutoff
Internal temperature below -40°
2-071 M1 Overload Trip
An existing overload condition has continued for a preset time period and
the power module has shut down the load.
2-072 M2 Overload Trip
2-073 M3 Overload Trip
2-074 M4 Overload Trip
2-075 M5 Overload Trip
2-076 M6 Stall
The motor current has exceeded the stall value. The motor will not be
operated in the stalled direction until it is first operated in the opposite
direction.
2-077 M7 Stall
2-078 M10 Stall
2-081 EEPROM Fault EEPROM checksum error
2-082 PDO Timeout
Time between PDO messages exceeded PDO timeout.
2-083 CAN Bus
Internal CAN Bus counter exceeded 128
2-084 Actuator Timeout
Internal master does not receive the slave message in the timeout period.
2-086 OverTemp Cutback
Internal temperature exceeded the cutback temperature. The output current
limits will be reduced.
2-087 UnderTemp Cutback The internal temperature is below -25°C. Output power will be reduced to
50%.
2-088 K2 Coil Open
The module has detected an open circuit at the K2 relay coil.
