Remedy
The complete list of the r2124 fault values is provided in the List
Manual.
0 ... 2: Fault in data cross-check between processor 1 and
processor 2. Remedy: Please refer to the List Manual.
3: Difference of the position actual value (r9713) between the two
monitoring channels is greater than the tolerance in
p9542. See also Section: Setting the gear ratio and actual value
tolerance (Page 107).
4 ... 43: Fault in data cross-check between processor 1 and
processor 2. Remedy: Please refer to the List Manual.
44 ... 57: The tolerance value for the monitoring function differs
between the two monitoring
channels. See also Section: Setting the gear ratio and actual value
tolerance (Page 107).
58 ... 999: Fault in data cross-check between processor 1 and
processor 2. Remedy: Please refer to the List Manual.
1000: Check (watchdog) timer has expired.
Too many signal changes at the F-DI
•
Remedy:
Check the F-DI wiring (contact problems).
•
1001: Initialization error of the check timer.
Remedy: Power on reset
•
Upgrade inverter firmware
•
1005: Pulses already canceled for test stop selection.
1011: Acceptance test status between the monitoring channels differ.
Diagnostics in the List Manual under r9571.
•
1020: Cyclic communication failure between the monitoring
channels.
Remedy: Power on reset
•
Replace the Control Unit or the inverter.
•
1040: Pulses in active encoderless monitoring functions canceled.
Deselect the active safety function.
•
Select and then deselect STO.
When the SLS monitoring function is active, you must switch on
•
the motor within 5 s of deselecting STO.
1041: Current value too low for encoderless actual value acquisition.
Reduce the minimum current (p9588).
•
1042: Current or voltage plausibility error.
Increase the ramp-up and ramp-down time (p1120/p1121).
•
Check whether the current and speed control settings are correct
•
(torque-forming, field-forming current and
actual speed value must not fluctuate).
Reduce the dynamic response of the setpoint.
•
Increase the minimum current (p9588).
•
Maintain an adequate wait time before switching on the motor,
•
also see:
– Switching on the motor when SLS is active (Page 201)
– Switching on the motor when SSM is active (Page 213)
– Switching on the motor when SDI is active (Page 219)
1043: Too many acceleration processes.
Increase the voltage tolerance (p9589).
