This section applies only if you purchased a G213V or have installed a G901X step pulse multiplier. A G203V without a step pulse 
multiplier has a fixed 10 microstep resolution. 
 
ADJUSTING MICROSTEP RESOLUTION 
 
The  G213V  has  an  onboard  step  pulse  multiplier  called  the  G901X  that  allows  the  drive  to  operate  in  full  step,  half  step,  5 
microstep and 10 microstep modes. The G901X uses a 2mm jumper block and two jumpers to set the resolution. The jumper 
block can be found by using the diagram below: 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Once the 

jumpers 

have been located they may be set according to the diagram below. Please note that the four pins closest to the optoisolator are 
unconnected and can be used as jumper storage. It is recommended that needle nose pliers or tweezers be used to adjust the 
jumper settings. The power to the G213V must be turned off before any adjustment is to be made on the step pulse multiplier. 
 
METHOD OF OPERATION FOR STEP PULSE MULTIPLIER: 
 
The G901X step pulse multiplier still allows all of the benefits of microstepping at low speeds and full stepping at high speeds that 
the G203V has. The step pulse multiplier works by outputting a set number of pulses to the main motor control board it is attached 
to, which is the G203V in the case of the G213V. 
 
If the step pulse multiplier is set to full stepping mode it will output ten microsteps for every pulse it receives on its input; as far 
as the base drive is concerned, it is always microstepping at its normal rate. This means that the drive will continue to morph to 
full step at higher speeds to allow the highest possible torque from the motor.
