XLT50-D/XLT50-S 3-AXIS STEPPER DRIVE

Solder Bridge Pads
Next to the bit-switch are six solder bridge pads numbered 1 to 6. By bridging the pad with
solder the functionality of each axis can be adjusted, as follows:
CAUTION – Risk of equipment damage
You must observe electrostatic precautions before attempting to make any changes to
the drive.

Table A-7. Use of Solder Bridge Pads
Note: [1] The standby current selected via pads 1, 2 & 3 is 50% or 70% of the bit-switch
(switches 3 to 8) selected current, not the maximum output current of the drive.
[2] Step-up/step-down control uses two independent step pulse trains, one for each direction
of rotation. Connect the step-down signal to the normal step input and the step-up signal to
the direction input.
