Regenerative deceleration
Short terminals RB1 and RB2 to
regeneratively decelerate a motor
to a stop (Figure 14). Since
terminal RB1 bypasses the MIN
SPD circuit, shorting RB1 and
RB2 will decelerate a motor to a
stop instead of minimum speed.
Calibrate the deceleration time by
adjusting the opposite-direction
acceleration trimpot.

Automatic restart upon power restoration
All drives automatically run to set speed when power is
applied. Wiring a latching relay into the AC line is one way to
prevent automatic restarting following a power outage.

Line Starting and Stopping
Line starting and stopping (applying and removing AC line
voltage) is recommended only for infrequent starting and
stopping of a drive. When AC power is applied to the
drive, the motor accelerates to the speed set by the speed
adjust potentiometer. When power is removed, the motor
coasts to a stop.
