Cause
The motor runs in reverse direction
at start
The difference between motor
parameter measured Rr and Rs
value is too large
Insufficient output torque is
dragged to the reverse direction by
the load.

N/A
Check if the motor is hold when started, or start the motor with speed source.
Normally the Rr value of IM is Rs*0.7. If there is much difference of the
measured value (e.g. Rr=Rs*0.3), proceed the motor parameter auto-tuning
again.
Increase the current limit of Pr. 06-12, so as to increase the output torque.
