Starting and Stopping Methods
Regenerative braking, coasting to a stop, or decelerating to
minimum speed 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 lines) is the only acceptable method for emergency
stopping.
For this reason, Minarik Drives strongly recommends installing an
emergency stop switch on both AC line inputs (see Figures 11 and
12 on pages 23 and 24).
Frequent starting and stopping can produce high torque. This
may cause damage to motors, especially gearmotors that are not
properly sized for the application.
!
WARNING!
All drives automatically run to set speed when power is applied, the drive
is enabled, and the inhibit is open.
Automatic Restart Upon Power Restoration
Line starting and 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 or analog signal. When AC line
voltage is removed, the motor coasts to a stop.
