: None ; Fault  Trouble  TroubleQuickstop ; Warning  WarningLocked  Information
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.

 None : Fault  Trouble  TroubleQuickstop  Warning  WarningLocked  Information
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.

; None : Fault  Trouble  TroubleQuickstop ; Warning  WarningLocked  Information
Cause Remedy
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.
• Check motor temperature monitoring.
• Provide for sufficient cooling of the motor.
• Check terminals for open circuit or loose contact.

; None ; Fault  Trouble  TroubleQuickstop : Warning  WarningLocked  Information
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).
Response (Lenze setting printed in bold) Setting: C00608 (; Adjustable response)
: None ; Fault  Trouble  TroubleQuickstop ; Warning  WarningLocked  Information
Cause Remedy
The device indicates that the maximally possible torque
at the motor shaft has been reached.
• C00057
displays the current torque.
Reduce motor load.
