Starting and stopping methods

Line starting and line stopping

Line starting and line stopping (applying and removing AC line

voltage) is recommended for infrequent starting and stopping of a

drive only. When AC line voltage is applied to the drive, the motor

accelerates to the speed set by the speed adjust potentiometer.

When AC line voltage is removed, the motor coasts to a stop.

Warning

Decelerating to minimum speed, dynamic braking, or coasting

to a stop is recommended for frequent starts and stops. 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.

For this reason, Minarik strongly recommends installing

an emergency stop switch on both the L1 and L2 inputs

(see connection diagrams on pages 20 & 21).
