MICROMASTER 411 & COMBIMASTER 411 Operating Instructions
6SE6400-5CA00-0BP0 91
DAC parameters should not be set to identical values, since this would produce illogical results.
Fault value = 0: Parameter settings for output identical
1: Parameter settings for input identical
2: Parameter settings for output do not correspond to DAC type
A0922 No load applied to inverter
Possible Causes
No Load is applied to the inverter.
As a result, some functions may not work as under normal load conditions.
A0923 Both JOG Left and JOG Right are requested
Possible Causes
Both JOG right and JOG left (P1055/P1056) have been requested. This freezes the RFG output
frequency at its current value.
A0936 PID Autotuning Active
Possible Causes
PID Autotuning (P2350) selected or running
A0952 Belt Failure Warning
Possible Causes
Load conditions on motor indicate belt failure or mechanical fault.
Diagnose & Remedy
Check the following:
No breakage, seizure or obstruction of drive train.
If using an external speed sensor, check for correct function. Check parameters:
P2192 (delay time for permitted deviation)
If using the torque envelope, check parameters:
P2182 (threshold frequency f1)
P2183 (threshold frequency f2)
P2184 (threshold frequency f3)
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 for permitted deviation)
