Cause Remedy
After switching on the device, the 24V supply voltage for
the control electronics is too low (100 ms after switch-on
U is < 19V).
With internal supply voltage via the power electronics,
the controller must be replaced.
With external supply voltage, check the correct
connection and/or the stability of the supply voltage.

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.
