General Description
This is a general purpose hand held controller with user selectable step frequency or step count display. It operates from a single external 6-24 VDC power supply to drive four phase stepping motors requiring up to 1.0 amp per phase.
Motor Connections
Motor phases 1 thru 4 are connected to the terminal block locations 1 thru 4 in sequence and the motor phase common leads are connected to terminals 5 and 6. The standard Hurst color code and switching sequence is:
Phase | Color | Terminal |
|
||||||||||||||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
1 | red | 1 | |||||||||||||||||||||||||||||||||||||
2 | blue | 2 | |||||||||||||||||||||||||||||||||||||
3 | black | 3 | |||||||||||||||||||||||||||||||||||||
4 | white | 4 | |||||||||||||||||||||||||||||||||||||
common | blue/white | 5 | |||||||||||||||||||||||||||||||||||||
common | black/white | 6 | |||||||||||||||||||||||||||||||||||||
Power Supply Connections
The D.C. supply is connected to terminals 7 and 8. Terminal 7 is the circuit common and terminal 8 is the positive voltage.
Switch Operations | |
---|---|
ON/OFF | Disconnects the incomming D.C. Supply voltage. |
ENABLE/DISABLE | Disables the output drivers. |
CD/CCW | Determines the direction of rotation. |
RUN/HOLD/JOG | This three position switch determines the controller's mode of operation. In the center position the motor remains in the holding mode with two phases energized. In the run position the motor steps continiously. The jog position is a monemtary contact which generates one step with each operation. |
DISPLAY | Selects either the speed (step frequency in pulses per second) or step count to be displayed. |
RESET | Resets the step counter to zero. |
SPEED ADJUST | Speed adjustment from aproximately 5 to 400 pulsed per second. |
