G210X ADJUSTMENTS
This section applies only if you purchased a G210X or have installed a G901X step pulse multiplier. A G201X without a step pulse
multiplier has a fixed 10 microstep resolution.
ADJUSTING MICROSTEP RESOLUTION
The G210X 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 G210X 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 G201X 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 G201X in the case of the G210X.
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.
