Cause
Remedy
The supply of the I/Os is overloaded. The total current at
pin 1 of X41 ... X43, X50 is higher than 1 A.
Check connected input sensors.
Do not exceed maximally available total current of 1 A.

Cause
Remedy
The heatsink temperature now only differs by 5 °C from
the shutdown temperature of the motor.
Prevent further heating, i.e. reduce motor load or set
controller inhibit so that the heatsink can cool down
again.

Cause
Remedy
The heatsink temperature is higher than the fixed limit
temperature (90 ° C).
Maybe the ambient temperature of the controller is too
high or the fan or its ventilation slots are dirty.
• Check control cabinet temperature.
• Clean filter.
• Clean controller.
• If required, clean or replace the fan.
• Provide for sufficient cooling of the device.

Cause
Remedy
The motor temperature monitoring at plug X21 has been
tripped.
Possible causes:
• The motor is overheated so that the thermal contact
integrated into the motor has been switched.
• An open circuit or a loose contact at the connections
mentioned above has occurred.
• Check motor temperature monitoring.
• Provide for sufficient cooling of the motor.
• Check terminals for open circuit or loose contact.

Cause
Remedy
The Ixt overload check has tripped.
Possible causes:
• Wrong dimensioning of the device with regard to its
motor load.
• Load cycles are not complied with.
• Check and, if required, correct dimensioning of the
device and the motor load with regard to technical
data.
• Reduce motor load cycles (observe load cycles
according to documentation).
