WARNING
ADJUSTMENT OF THE PROCESS INTERFACE BIAS POTENTIOMETER
COULD RESULT IN ZERO SPEED OPERATION OF THE CONTROLLER. THE
DRIVE IS INTENDED TO OPERATE AT A PREDETERMINED MINIMUM SPEED
UNLESS DISCONNECTED FROM THE POWER SOURCE. IF THE APPLICA
TION REQUIRES ZERO SPEED OPERATION WITHOUT SUCH DISCONNEC
TION, THE USER IS RESPONSIBLE FOR ASSURING SAFE CONDITIONS FOR

It may be necessary to repeat Steps 5 and 6 until proper maximum
and minimum speed or torque are attained because these
adjustments interact.
7. Press the Stop switch and wait for the motor to completely stop.
