Issue 01/06 | Faults and Alarms |
A0920 ADC parameters not correctly set
Cause
ADC parameters should not be set to identical values, as this would lead to illogical results.
-Index 0: Parameter settings for output identical.
-Index 1: Parameter settings for input identical.
-Index 2: Parameter settings for input do not correspond to ADC type.
A0921 DAC parameters not set properly
Cause
-DAC parameters (P0777 and P0779) have identical values.
OR
-DAC parameters (P0778 and P0780) have identical values. Identical values would produce illogical results.
Diagnosis & Remedy
Check the following:
-Output parameter settings. Ensure P0777 and P0779 are not identical.
-Input parameter settings. Ensure P0778 and P0780 are not identical.
A0922 No load at the inverter
Cause
-no load is connected to the inverter.
-therefore several functions can run differently than under normal load conditions.
A0923 JOG
Cause
-both JOG clockwise and JOG
A0952 Load fault detected
Cause
-load conditions at the motor indicate a load fault or mechanical fault.
Diagnosis & Remedy
Please check the following:
-no braking, failure or destruction of the mechanical transmission line
-if required, lubricate the mechanical transmission line.
If you are using an external encoder, please check the following parameter settings:
-P2192 (delay time, load torque monitoring)
If you are using a specific speed range, then please check the following:
-P2182 (load torque monitoring F1)
-P2183 (load torque monitoring F1f2)
-P2184 (load torque monitoring F1f3)
-P2185 (upper torque threshold 1)
-P2186 (lower torque threshold 1)
-P2187 (upper torque threshold 2)
-P2188 (lower torque threshold 2)
-P2189 (upper torque threshold 3)
-P2190 (lower torque threshold 3)
-P2192 (delay time, load torque monitoring)
A0936 PID auto tuning active
Cause
-PID auto tuning (P2350) is selected or is presently running.
Diagnosis & Remedy
-after automatic PID optimization has been completed, the alarm is reset.
