Warning
The inhibit circuit is used for frequent starts and stops. It
must never be used as an emergency stop. It 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
a STOP/START switch for emergency stopping.
Inhibit circuit (MM21051C ONLY)
Maintaining a connection between the inhibit pins causes the motor
to coast to zero speed. Removing the connection between the
inhibit pins allows the motor to accelerate to the speed set by the
speed adjust potentiometer (Figure 10).
