Thank you for purchasing the G201X drive. The G201X microstep drive is warranted to be free of manufacturing defects for 1
year from the date of purchase. Also anyone who is dissatisfied with it or is unable to make it work will be cheerfully refunded the
purchase price if the G201X is returned within 15 days of the purchase date.
Before beginning, be sure to have a suitable step motor, a DC power supply suitable for the motor and a current set resistor. The
motor's rated phase current must be between 0 Amps and 7 Amps. The power supply voltage must be between 4 times and 20
times the motor's rated voltage. The current set resistor may be a 1/4 Watt, 5% part. Finally have a STEP and DIRECTION pulse
source available.
DIFFERENCES BETWEEN THE G201X AND G201
The G201X is 100% backwards compatible with the G201 and G210. It has several new features and performance
enhancements:
1.)
STEP and DIRECTION is +3.3VDC and +5VDC compatible at 2.5mA
2.)
Recirculate mode during STANDBY greatly reduces motor heating while stopped
3.)
No external 470uF capacitor needed
4.)
Power-on RESET
5.)
Direction is clocked in on the active step pulse edge
6.)
No internal jumpers, no current set resistor, DIP switch settings
7.)
Low motor heating while stopped
8.)
Universal step and direction COMMON
G201X TERMINAL WIRING
The G201X uses a 2-piece modular main connector. The connector is split in two pieces; terminals 1 through 6 (power supply and
motor leads) and terminals 7 through 12 (control interface). Each can be removed separately by pulling the connector body
upwards and off of the mating header pins on the G201X. The connectors must initially be removed to mount the G201X to a
heatsink or chassis.
TERMINAL 1
Power Ground
Connect the negative (black) lead of your power supply to this terminal.
TERMINAL 2
Power (+)
Connect the positive (red) lead of your power supply to this terminal. It must be between +18VDC to
+80VDC.
TERMINAL 3
Motor Phase A
Connect one end of your "Phase A" motor winding here.
TERMINAL 4
Motor Phase /A
Connect the other end of your "Phase A" motor winding here.
TERMINAL 5
Motor Phase B
Connect one end of your "Phase B" motor winding here.
TERMINAL 6
Motor Phase /B
Connect the other end of your "Phase B" motor winding here.
TERMINAL 7
Disable
This terminal will force the winding currents to zero when shorted to ground (TERMINAL 12).
TERMINAL 8
Direction
Connect the DIRECTION signal to this terminal.
TERMINAL 9
Step
Connect the STEP signal to this terminal.
TERMINAL 10
Common
Connect the controller's +3.3VDC, +5VDC or GND to this terminal.

- Page 1 7 through 12 (control interface). Each can be removed separately by pulling the connector body upwards and off of the mating header pins on the G201X. The connectors must initially be removed to mount the G201X to a heatsink or chassis.
- Page 2 3 and 4. CAUTION! Do not short the motor leads to each other or to ground; damage will result to the G201X. 4-wire, 6-wire and 8-wire motor may be used. When 6-wire motors are used, they may be connected in half winding or full winding.
- Page 3 This terminal will force the winding currents to zero when shorted to ground (TERMINAL 12). Shorting this input to ground (term. 7 to 12) forces winding currents to zero and stops all output switching activity. The G201X will continue totalizing step and direction inputs if any are sent. The power supply current drops to less than 15mA. The motor will return to its original position when the disable input is released if no step pulses have been sent and the motor has not been moved more than 2 full steps.
- Page 4 Automatic Current Standby The G201X reduces motor phase current to 50% of the set value when the motor is stopped. This can reduce motor heating up to 4-fold while the motor is not moving. If enabled, this reduction occurs 1 second after the last step pulse is sent to the drive.
