INSTALLATION
WARNING:
This control should only be installed by a qualified person familiar with
its operation and associated hazards. The National Electrical Code (NEC), local
electrical and safety codes, and when applicable, the Occupational Safety and
Health Act (OSHA) should be observed to reduce hazards to personnel and property.

Instructions for Installation and Operation
Type WPM Filtered PWM Speed Controls for Permanent Magnet DC Brush Motors
• Models 0790 & 0791, NEMA 1 enclosure
Step 1: Mounting the Control
The control may be mounted using any two or all four mounting holes. The mounting
holes have clearance for 1/4-20 or M6 screws.
Step 2: Preliminary Setup
HORSEPOWER & ACCELERATION SELECTOR SWITCHES–
Control models 0790 and
0791 are packaged with the enclosure cover unattached. Remove the cover to set
the horsepower and acceleration selector switches.
Figure 4
shows the location of
a bank of 8 dip switches. Set switches 1 through 6 to match the type, speed, and
current ratings on the Bodine motor nameplate per
Figure 2
(consult Bodine on
settings for non-Bodine motors). Set switches 7 and 8 to select the acceleration/
deceleration time range per
Figure 3.
Step 3: Electrical Connections
The enclosure cover must be removed as shown in
Figure 4
to make the electrical
connections.
WARNING–
All parts of the circuit operate at voltages capable of causing
serious injury or death.
WARNING–
The AC power line to the control should be the last connection made.
CAUTION–
The control board signal common is not at ground potential. Any
external signal or equipment connected to the control must be electrically
isolated from ground.
INHIBIT SWITCH (OPTIONAL)–
A mechanical switch or relay with contacts rated
for low voltage may be connected to terminals “H1” and “H2”. With the switch
open, the motor will run. With the switch closed, the motor will coast to a stop.
WARNING–
The inhibit switch should not be used to disable motor or control
when servicing these or driven equipment. Disconnect the AC power instead.

1. For armature speed of a geared motor, multiply the output speed at the driveshaft by the
gear ratio.
2. If the user desires to install their own armature fuse on the control output to protect the motor
from continuous overloads, base fuse ratings on the motor rating in this column.
3. Peak current available with TORQ pot in fully CW position (factory setting). This current exceeds
the continuous rating of the motor and is for intermittent overload conditions only.
4. Use this column for sizing a line fuse on the control input.
5. The REG potentiometer must be turned fully CCW (off) for high-speed type 24ABEPM motor.
6. Time for voltage across A1 and A2 to ramp up to 130 V when speed pot is turned from 0 to 100;
or to ramp down to 0 V when it is turned from 100 to 0. The time for a motor to accelerate from 0
to 2500 rpm or decelerate from 2500 to 0 rpm is dependent on motor size and loading conditions.
