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).
• The current supply voltage is displayed in C00065
.
With internal supply voltage via the power electronics,
the inverter must be replaced.
With external supply voltage, check the correct
connection and/or the stability of the supply voltage.

Cause Remedy
In order to protect the device from overload, the
following device outputs have a hardware detection in
the mains input: 7.5 kW, 11 kW, 15 kW, 30 kW, 37 kW, 45
kW.
In case of the error message "Su06", this hardware
detection has responded.
• Check whether all mains phases are connected (a 2-
phase supply may be existent).
• Provide for sufficient cooling of the device.

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 inverter.
• If required, clean or replace the fan.
• Provide for sufficient cooling of the device.
