38 Troubleshooting
Motor will not stop at zero speed setting
The MIN SPEED adjustment is set too high.
Motor runs in reverse
Disconnect AC power. Reverse the armature connections. Restore
power to the control.
Motor slows under increased load
The IR COMP adjustment may be set too low. Increase the setting
until the speed remains acceptably constant over the load
range.
Motor speed is unstable under load
The IR COMP adjustment may be set too high. Decrease it until
the symptom disappears.
The motor may be “bouncing” in and out of current limit. Verify
that the TORQUE setting (CURR LIMIT on PCM2x000C series
drives) is sufficient for your application. Increase the setting if it
is too low.
Motor runs at full speed at all times
If in the MANUAL mode, the speed adjust pot, or leads from the
pot to the control, may be open.
