oC11: Current clamp for too long (>1 sec) [xx.0123.00071]
ot2: Speed controller limitation [xx.0123.00093]
oC6: I2xt overload - motor [xx.0123.00105]

Sd10: Speed limit - feedback system 12 [xx.0123.00200]
Response (Lenze setting printed in bold)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
The device indicates that the "CLAMP" overcurrent limi-
tation has been activated.
• A permanent clamp operation causes an overload dis-
connection.
Reduce setpoint generation dynamics or motor load.
Response (Lenze setting printed in bold) Setting: C00567 ( Adjustable response)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
The output of the speed controller has reached the inter-
nal limit value. In this status, the speed controller is not
able anymore to correct the system deviation.
• Only during "Closed loop" operation or with vector
control (SLVC).
• Observe load requirements.
• Correct dimensioning or reduce setpoint generation
dynamics if necessary.
 Motor control
Response (Lenze setting printed in bold) Setting: C00606 ( Adjustable response)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
Thermal overload of the motor. Only self-ventilated motors can be monitored using the
I2xt function.
• Check whether it is a self-ventilated motor. If not, set
( C00606 ) to "0: No Reaction".
• Observe load requirements.
• Correct dimensioning if necessary.
• For VFCplus control type: Check Vmin boost ( C00016 ).
 Set Vmin boost
Response (Lenze setting printed in bold) Setting: C00597 ( Adjustable response)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
Motor phase failure Motor connections/check wiring unit.
Response (Lenze setting printed in bold) Setting: C00607 ( Adjustable response)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
Maximally permissible speed of the feedback system
connected to DI1/DI2 reached.
Reduce speed of the rotation shaft/feedback system.
