Operation
Warning
For frequent starts and stops, use dynamic braking, inhibit
mode, or decelerating to a stop (shorting S2 to S1). Do
not use any of these methods for emergency stopping.
They may not stop a drive that is malfunctioning.
Removing AC line power (both L1 and L2) is the only
acceptable method for emergency stopping.
Minarik strongly recommends the installation of an
emergency stop switch for chassis drives. The switch
contacts should be rated at a minimum of 250 volts and
200% of maximum motor current.
To shut down the drive:
To decelerate the motor from set speed to a stop, set the speed
adjust potentiometer to zero speed. To coast the motor from set
speed to a stop, remove AC line voltage from the drive or short
SO501 terminals H1 and H2.
Reversing
Refer to Application Notes (page 25) for reversing options, or
contact your Minarik sales representative.
