DC Motor Controller
Operations Manual
Operating Specifications:
Supply voltage required: 120VAC@60Hz
RS232 output communications: 9 pin serial ASCII output
Analog output communications: 0 to +10Vdc output
Torque: 0z/in
Operating Instructions:
Standard Controller:
1- Attach the motor plug to the receptacle located on the rear of the motor controller unit (turn and
locks).
2- Turn the speed control knob on the face of the controller counter-clockwise until it stops.
3- Plug the motor controller into the appropriate power receptacle.
4- Turn the power switch to
“ON”.
5- Switch the Speed/Torque switch to the Speed position.
6- Select the desired motor direction either Forward (CW) /Reverse (CCW). Note: the direction may be
changed at any time. The motor will slow to a stop and change direction.
7- Turn the speed control knob clockwise until the desired speed
(RPM’s) is shown on the display.
8- To display the torque, press the Speed/Torque switch to the Torque position.
Torque: Torque is displayed in oz/in. The torque displayed on startup is the torque required to maintain
the motor at the set rpm’s. This value will vary per controller and per motor. When the motor requires
more torque to maintain the set rpm’s the value will increase.
Note: Controllers are calibrated to test motors running at 350
– 500 rpm’s for a minimum of 40 minutes.
This allows the motors to “warm-up” before the controllers are calibrated.
Controller with Communications:
Serial Output:
(Any standard 9-pin RS-232 cable is required)
The serial port
sends a digital output signal every 10 seconds to a computer’s serial port via
Windows HyperTerminal or through another data logging program. The serial output allows the unit to
digitally output whatever is displayed on the Motor controller readout. To change the output time
duration; refer to
Adjusting the Output Time Duration
.
Computer communications port settings:
Bits per second: 9600
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None
Windows HyperTerminal Setup:
1- Start the Microsoft HyperTerminal program on the PC.
2- Select
Properties
from the
File
menu.
3- Select your COM port from the
