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 b18VDC 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 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. 

 
TERMINAL 11 

Current Set (OPTIONAL) 

 

 

Connect one end of your current set resistor to this terminal. 

 
TERMINAL 12 

Current Set (OPTIONAL) 

 

 

Connect the other end of your current set resistor to this terminal.
