Error messages of the operating system
OC12: I2xt overload - brake resistor [xx.0123.00065]
OT2: Speed controller output limited [xx.0123.00093]
OC6: I2xt motor overload [xx.0123.00105]
SD10: Speed limit - feedback system 12 [xx.0123.00200]

Response (Lenze setting printed in bold)
0: No Reaction : 1: Fault 2: Trouble 4: WarningLocked
Cause Remedy
Too frequent and too long braking processes. • Check drive dimensioning.
• Check parameterisation ( C00129 , C00130 , C00131 ).
Response (Lenze setting printed in bold) Setting: C00567 (

Adjustable response)
: 0: No Reaction ; 1: Fault 2: Trouble ; 4: WarningLocked
Cause Remedy
The output of the speed controller has reached the
internal limit value. In this state, the speed controller is
not able anymore to correct the system deviation.
• Only with "Closed loop" operation or vector control
(SLVC).
• Observe load requirements.
• If required, correct dimensioning or reduce dynamics
of the setpoint generation.

Cause Remedy
Thermal overload of the motor. • Observe load requirements.
• Correct dimensioning if necessary.
• In case of VFCplus operation: Check Vmin boost
( C00016 ).
