Operation
Line starting and stopping
When AC line voltage is applied to the drive, the motor
accelerates to the set speed. When AC line voltage is removed,
the motor coasts to a stop. Line stopping (removing AC line
voltage) is recommended for stopping in emergency situations
only. It is not recommended for frequent starting and stopping.
For this reason, Minarik strongly recommends that you install a
stop switch on the line voltage inputs (both L1 and L2). Refer to
Figure 3 (page 13).
Automatic restart of the drive
When line voltage is applied to the drive, the motor will
automatically accelerate to the speed commanded by the speed
adjust potentiometer or reference signal. Wiring a latching relay
into the motor control circuit is one way to prevent undesirable
restarts.
