Fault Cause Remedy
F30074: Communication er‐
ror between the Control Unit
and Power Module
Reaction: NONE
Acknowledgement: IMMEDI‐
ATELY
Communications between the Control Unit
(CU) and Power Unit (PU) via the interface
no longer possible. The CU may have been
withdrawn or is incorrectly inserted.
Fault value (r0949, interpret hexadecimal):
0 hex:
● a Control Unit with external 24 V supply
was withdrawn from the Power Unit
during operation.
● with the Power Unit switched off, the
external 24 V supply for the Control unit
was interrupted for some time.
1 hex:
The Control Unit was withdrawn from the
Power Unit during operation, although the
encoderless safe motion monitoring func‐
tions are enabled. This is not supported.
After reinserting the Control Unit in opera‐
tion, communications to the Power Unit no
longer possible.
20A hex:
The Control Unit was inserted on a Power
Unit, which has another code number.
20B hex:
The Control Unit was inserted on a Power
Unit, which although it has the same code
number, has a different serial number.
601 hex:
The Control Unit was inserted on a Power
Unit, whose power/performance class
(chassis unit) is not supported.
Reinsert the Control Unit (CU) or the Control
Unit adapter (CUAxx) onto the original Power
Unit (PU) and continue operation. If required,
carry out a POWER ON for the CU and/or the
CUA.
F31100: Zero mark distance
error
Reaction: ENCODER
Acknowledgement: PULSE
INHIBIT
The measured zero mark distance does not
correspond to the parameterized zero mark
distance.
For distance-coded encoders, the zero
mark distance is determined from zero
marks detected pairs. This means that if a
zero mark is missing, depending on the pair
generation, this cannot result in a fault and
also has no effect in the system.
● Check that the encoder cables are routed in
compliance with EMC.
● Check the plug connections.
● Check the encoder type (encoder with
equidistant zero marks).
● Replace the encoder or encoder cable.
F31110: Serial communica‐
tions error
Reaction: ENCODER
Acknowledgement: PULSE
INHIBIT
Serial communication protocol transfer er‐
ror between the encoder and evaluation
module.
● Check the encoder cable and shielding
connection.
● Replace the motor.
F31112: Error bit set in the
serial protocol
Reaction: ENCODER
Acknowledgement: PULSE
INHIBIT
The encoder sends a set error bit via the
serial protocol.
● Check the encoder cable and shielding
connection.
● Replace the motor.
