Fault /
Warning
Description Cause / Remedy
Warning
• Motor power (P0307) must match inverter power (r0206)
A0511
Motor Over
temperature Warning
• Load duty cycle must be correct
• Check if name plate data are correct (if not perform quick
commissioning)
• Accurate equivalent circuit data can be found by performing motor
identification (P1910=1)
• Check if motor weight (P0344) is reasonable. Change if necessary
• Check if temperature shown in r0035 is reasonable
A0541
Motor Identification
Active
• Motor data identification (P1910) selected or running
A0910
VDC Max Controller
Deactivated Warning
• Occurs if line supply voltage (compared to P0210) is permanently
too high
• Occurs if motor is driven by an active load, causing motor to go into
regenerative mode Occurs at very high load inertias, when ramping
down
A0911
VDC Max Controller
Active Warning
• Vdc max controller is active; so ramp-down times will be increased
automatically to keep DC-link voltage (r0026) within limits (P2172).
A0920
Analog Input
Parameters Incorrect
Warning
• AIN parameters incorrect – check that they are not set to identical
values.
• Check that parameters are logical for AIN type.
A0921
Analog Output
Parameters Incorrect
Warning
• AOUT parameters are incorrect. Check that settings are not
identical to each other.
A0922
No Load Applied to
Inverter Warning
• No Load is applied to the inverter – (Motor not connected) - Check
wiring to motor.
A0923
Jog Left and Jog Right
Applied Warning
• Both JOG right and JOG left (P1055/P1056) have been requested.
This freezes the RFG output frequency at its current value.
