Timeout during motor identification
Error during identification of motor parameters. The maximum per-
mitted phase voltage (= 80 V) was exceeded during the resistance
measurement.
m
Possible cause:
Incorrect motor nominal current setting in Parameter 107.09.
n
Effect:
Output voltage set to ZERO to protect the motor. An additional
drive block occurs with standard error response.
Resetting after error elimination:
Error reset is possible. Timeout (45 seconds) with R measurement
with motor parameter identification, such as due to error during cur-
rent / voltage measurement or normalization or limit value.

Special function already used for
another digital input
Special function such as hardware limit switch 1 was already used
for another digital input

Digital output already used
This digital output is already used by another special function or by
another assignment.

Reference run required and not carried
out
Reference run required and not yet carried out
The start of the active operating mode requires a one-time reference
run (homing) after activating the controller.
Currently, only the operating mode Position Target Specification (BA
= 1) requires homing. This requirement can be activated in the mode
for the position target specification.

Problem during homing
A homing error has occurred. Possible error causes:
m
An invalid homing mode was selected.
m
Homing isn't possible because of limit switch and reference switch
status.
m
A maximum distance was set for the zero pulse search and the
zero pulse was not detected within the specified distance.

Monitoring the block for positive direc-
tion
Monitoring the block for positive direction:
Monitoring has detected a positioning attempt in positive direction
No response

Monitoring the block for negative direc-
tion
Monitoring the block for negative direction:
Block for negative direction has detected a positioning attempt in
negative direction.

Positioning time monitoring reports
Timeout
Positioning time monitoring reports Timeout
Monitoring will become active as soon as the position set value is
equal to the target position at the end of positioning.
If the actual position is not located in the positioning window (Param-
eter 121.5) after the time set in Parameter 118.18 has expired, the
error will be triggered.
