68 Communication fault
during remote
parameter setting via
system bus (C0370)
(configurable in C0126)
Participant does respond or is not
available
l Check whether bus terminator available
l Check screen contact of the cables
l Check PE connection
l Check bus load, if necessary, reduce the
baud rate

OC1

11 Short circuit
Short circuit l Find reason for short circuit; check
motor cable
l Check braking resistor and cable for
braking resistor
Excessive capacitive charging current
of the motor cable
Use shorter motor cables with lower
charging current
OC2

12 Earth fault
Grounded motor phase Check motor, check motor cable
Excessive capacitive charging current
of the motor cable
Use shorter motor cables with lower
charging current
Deactivate earth−fault detection for testing
purposes
OC3

13 Overload inverter
during acceleration or
short circuit
Acceleration time too short (C0012) l Increase acceleration time
l Check drive selection
Defective motor cable Check wiring
Interturn fault in the motor Check motor
OC4

14 Overload controller
during deceleration
Deceleration time set too short
(C0013)
l Increase deceleration time
l Check size of external brake resistor
OC5

15 Controller overload in
stationary operation
Frequent and long overload Check drive selection
