Use a single-pole, three-position switch with a single speed adjust
potentiometer to stop a motor between reversals (Figure 19). Set the switch
to the center position to decelerate the motor to a stop.
Application Notes
FWD-STOP-REV switch
Figure 19. Forward-Stop-Reverse Switch
ATTENTION: Starting and stopping with the inhibit terminal pins
does not disconnect AC power in the stop position. A hardwired AC
power disconnection switch must be mounted in close proximity to the
operator’s start/stop controls. This is required, as the DC3 drive does
not have an armature loop contactor. A single fault like a power device
short may cause motor rotation when in the stop mode. The user is
responsible for assuring safe conditions for operating personnel by
providing suitable guards, audio or visual alarms, or other devices.
Failure to observe these precautions could result in bodily injury.
