Gain adjustment of the speed controller:
1.With low motor speed, increase V
pn
until
the drive starts to oscillate (high
frequency).
2.Reduce V
pn
, until the drive runs
smoothly.

Data on the motor nameplate are
setpoints for the field current. With very
low field currents an auxiliary starting
circuit should be provided.
