Su06: Mains input overload [xx.0111.00006]
Response (Lenze setting printed in bold)
0: No Reaction
Cause
Overtemperature in case of devices from type 6 in the
input rectifier or the mains choke.
oH4: Heatsink temp. > shutdown temp. -5°C [xx.0119.00000]
Response (Lenze setting printed in bold)
0: No Reaction
Cause
The heatsink temperature now only differs by 5 °C from
the shutdown temperature of the motor.
oH1: Overtemperature heatsink [xx.0119.00001]
Response (Lenze setting printed in bold)
0: No Reaction
Cause
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.
oH3: Motor temperature (X106) triggered [xx.0119.00015]
Response (Lenze setting printed in bold)
0: No Reaction
Cause
The motor temperature monitoring function at the plug
connector X106, terminal T1 /T2, has 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.
