Er40
Motor
switchover
during
running
status
Change the selection of the motor
via terminal during running of the
drive.
Perform motor switchover after
the drive stops.

parameters are set incorrectly.
Set the motor over speed check
parameters correctly based on
the actual situation.
Er/AL42
Motor over
speed
The encoder parameters are set
incorrectly.
Set the encoder
parameters properly.
The motor auto-tuning is not
performed.
