11.4.1 System error messages
The system error messages are generated in the operating system in the target system and
cover all impermissible, drive-based states (e.g. overcurrent, undervoltage, error in the
feedback system, …).
The following system error messages can occur in the ServoPLC:
Error
number
Error code Cause Remedy
Real short circuit between motor phases Disconnect motor and measure between winding
connections for short circuits
Disconnect supply cable and check between phases for
short circuit.
Operate inverter without load: the error should now reset
itself. If this is not the case, there is an internal short
circuit => replace controller or send for repair
11 OC1
High, capacitive charging current on the
motor cable Use shorter/lower capacitance motor cable
Fit choke to the output phases on the controller.
Real short to earth on one of the motor
phases Disconnect motor and check winding connections for
short to earth.
Disconnect supply cable and check between phases and
earth for short circuit.
Operate inverter without load: the error should now reset
itself. If this is not the case, there is an internal short to
earth => replace controller or send for repair 12 OC2
High, capacitive charging current on the
motor cable Use shorter/lower capacitance motor cable
Fit choke to the output phases on the controller.

Check drive dimensioning; if necessary increase drive
power.
16 OC6 I 2 x t overload (C0120) Check drive dimensioning; if necessary increase drive
power.
17 OC7 I 2 x t overload (C0130) Check drive dimensioning; if necessary increase drive
power.
18 OC8 I 2 x t overload (C0127) Check drive dimensioning; if necessary increase drive
power.
Mains voltage too high Check mains voltage.
Check controller for correct adjustment of the mains
voltage (code C0173/000)
Check drive dimensioning.
Energy fed back during braking
excessive (regenerative operation) On individual operation of the drive from supply:
-
Extend deceleration ramps (codes C0013/000,
C0105/000)
- If possible: set up DC-bus connection to other
controllers
- Use braking unit or supply unit and brake module
or regenerative module
- Check controller for correct adjustment of the
mains voltage (code C0173/000)
- Check drive dimensioning
In case of drives with DC bus connection:
-
Check fuses on all controllers on the DC bus as
well as fuses in the brake modules/power supply
modules/regenerative modules
- Check controller for correct adjustment of the
mains voltage (code C0173/000)
- Check drive dimensioning
