Cause / Remedy
•
Motor power (P0307) must match inverter power (r0206)
•
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
•
Motor data identification (P1910) selected or running
•
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
•
Vdc max controller is active; so ramp-down times will be increased
automatically to keep DC-link voltage (r0026) within limits (P2172).
•
AIN parameters incorrect – check that they are not set to identical
values.
•
Check that parameters are logical for AIN type.
•
AOUT parameters are incorrect. Check that settings are not
identical to each other.
•
No Load is applied to the inverter – (Motor not connected) - Check
wiring to motor.
•
Both JOG right and JOG left (P1055/P1056) have been requested.
This freezes the RFG output frequency at its current value.
