SECTION III
OPERATION
POWER ON/OFF
To energize the drive, turn-on the AC supply voltage to the controller. When this occurs, the motor shunt
field energizes with rated field voltage, and potentially hazardous voltage is present at the motor armature termi-
nals. These voltages can cause electric shock resulting in personal injury or loss of life.
If the AC supply is interrupted, and the controller is not set up for line starting, the motor will not restart
when the AC supply is restored until the controller is reset by initiating a Stop command and then a Start command.
If the controller is set up for line starting, and the AC supply is interrupted, the motor will restart when the AC sup-
ply is restored, provided the external AC line contactor is pulled in.
RUN
If a RUN-STOP-JOG switch is used, place the switch in RUN position. Otherwise, initiate a Run command.
A Run command will accelerate the motor to the setting of the MOTOR SPEED potentiometer or external speed
reference signal, as applicable. The rate of acceleration is preset by the ACCEL potentiometer on the controller
control board.
STOP
If a RUN-STOP-JOG switch is used, place the switch in STOP position. Otherwise, initiate a Stop command.
A Stop command will stop the motor at a rate proportional to the stopping rate of the motor load.
If the controller has dynamic braking, the motor stopping time will be reduced. Dynamic braking provides
exponential rate braking of the motor armature, which occurs when the circuit is opened between the controller and
the motor armature, and one or more resistors connect across the motor armature.
The dynamic braking resistors provide initial braking torque as shown in Table 5.

BRAKING RESISTORS TO BE EXCEEDED.
