 0: No Reaction  1: Fault  2: Trouble  3: TroubleQuickStop  4: WarningLocked  5: Warning  6: Information
Cause Remedy
The signals of the encoder connected to the encoder
interface are outside the defined operating range of the
motor temperature detection.
• Check contacts of the encoder cable at the motor and
controller.
• Check the selected motor temperature sensor in
C01190/2 as to whether it complies with the
assembly in the motor.
• If required, switch off thermal sensor monitoring
( C00583/6 ="0").
Response (Lenze setting printed in bold) Setting: C00604 ( Adjustable response)
 0: No Reaction  1: Fault  2: Trouble  3: TroubleQuickStop  4: WarningLocked  5: Warning  6: Information
Cause Remedy
The Ixt overload check has tripped.
• Operating threshold = 100 % Ixt (adjustable in
C00123 )
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).

 0: No Reaction  1: Fault  2: Trouble  3: TroubleQuickStop  4: WarningLocked  5: Warning  6: 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.
Response (Lenze setting printed in bold)
 0: No Reaction  1: Fault  2: Trouble  3: TroubleQuickStop  4: WarningLocked  5: Warning  6: Information
Cause Remedy
Maximum current monitoring has tripped.
• The instantaneous value of the motor current has
exceeded the limit value set in C00939 .
Check and, if required, correct dimensioning of the load
with regard to the installed device power.
