DC Motor Controller Operations Manual
Operating Specifications:
Supply voltage required: 230VAC @ 50Hz
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.
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- Toggle the Speed/Torque switch to the Speed position.
6- Select the desired motor direction either Forward/Reverse.
7- Turn the speed control knob clockwise until the desired speed is shown on the display.
8- To display the torque, toggle 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.
Controller with Communications:
Serial Output:
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 Connect using pull down menu.
4- Click the Configure button.
5- Adjust the pull down menus to the settings listed above.
6- Click OK.
7- Click on the Settings tab.

8- Select Auto Detect from the Emulation pull down menu.
9- Click on the ASCII Setup button.
10- Check the Echo typed characters locally check box.
11- Click OK.
12- Click OK.
Now if the communication port is configured correctly the displayed value on the controller should appear in
the HyperTerminal window. The controller is set to output a value every 10 seconds; this value can be adjusted if
needed.
Adjusting the output time duration:
1- Depress the Program and Down button on the display window.
2- Press the Program Button repeatedly until the display toggles between [SPC_5] and [000].
3- Using the Up or Down buttons adjust the display to read [007].
4- Press the Program button until [on_t] and [00010] is displayed.
5- Using the Up or Down buttons adjust the display to read the desired output time in seconds.
6- Press the Program button.
7- Depress the Program and Down button.
Analog Output:
The analog outputs the Forward RPM value only. The analog is set to output 10Vdc when the controller’s speed
is at 100% and 0Vdc when set 0%. To approximate the analog output value per volt dc, divide the max rpm
display by 10. This will give you rpm’s per 1-volt dc.
Example:
Max RPM: 250
250/10= 25
Therefore every 25 rpm’s = 1Vdc
In this example: If 45 rpm’s are displayed, then the analog output is about 1.8 Vdc
(45/25 = 1.8 Vdc)
Note: Analog output will not work properly when the motor is reversed or when the motor controller is switched
to Torque. To display torque or the motor’s rpm’s in reverse use the Serial output.
1- Attach the yellow analog cable to the Analog port located in the rear of the motor controller.
2- Attach the brown wire to the (+ Vdc) terminal on your analog input device.
3- Attach the blue wire to the (- Vdc) terminal on your analog input device.
