    XLT50-D/XLT50-S 3-AXIS STEPPER DRIVE Power and Motor Connections Make all DC input connections to the upper part of X4/5, the lower screw connections are used for motor outputs, detailed in Table A-1. Pin N of X4/X5 Function HV (24-85V) 0V (return for HV)
  • Page 5 XLT50-D/XLT50-S 3-AXIS STEPPER DRIVE Motor Connections (at the motor) Make motor connections directly between the drive and motor, do not use any switching devices, such as a contactor, in the motor supply cables. The majority of applications use an eight-lead motor with the windings connected in parallel or series, as shown in Figure A-3.

  • Page 6: Input Configuration

    Control XLT50 Drive Input Configuration The XLT50 drive is available in two versions: • XLT50-D Differential step/direction inputs • XLT50-S Single-ended step/direction inputs The use of differential inputs gives the option of good electrical noise immunity and finds greatest use where control signals have to be routed long distances in electrically noisy environments.

  • Page 8 XLT50-D/XLT50-S 3-AXIS STEPPER DRIVE Drive Shutdown 10nF Figure A-6. Shutdown Input Circuit Configuration The Shutdown input circuit forms a filter that introduces an approximate 1mS delay, which reduces the chances of false triggering of the Shutdown input. Fault Ouputs The individual Fault 1, 2 & 3 outputs indicate an over-current fault has occurred on a particular axis (1, 2 or 3).

  • Page 9: Bit Switch Settings

    XLT50-D/XLT50-S 3-AXIS STEPPER DRIVE Bit Switch Settings The bit switch mounted behind connector X1 controls the resolution of the drive in steps/rev. The switch also controls the current level settings of the individual axes as a percentage of the full output current obtainable. Resolution is set using bit switches 1 and 2, as indicated in Table A-5.
  • Page 10 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.
