XLT50-D/XLT50-S 3-Axis Stepper Drive
General Description
Based upon the XL50 single axis drive, the XLT50-D/-S offers a cost-effective 3-axis drive
solution in a single open-frame package. The XLT50-D/-S offers the following benefits:
• Reliable design based upon the XL50
• Cost-effective solution for 3-axis application
• Available with differential (-D) or single-ended (-S) inputs
Physical Appearance
The drive is contained within an open-frame aluminium case as shown in Figure A-1.
Mounting holes allow it to be attached to a panel using two 4mm screws.

Dimensions
The overall dimensions of the drive are 141mm deep, 40mm wide (including P-clips) and
172mm high. The distance between centre fixings is 185mm and the overall height of the
flange mount is 195mm.
Mounting Information
Mount the drive vertically. Both the top 4.5mm diameter fixing hole and the bottom 4.5mm
width fixing slot should be used.
Mount the supply with a minimum free space of 50mm both below and above its case. Allow
a side clearance of 10mm free space on both sides.
Note, do not mount the supply above or close to other products which generate a significant
amount of heat by radiation or convection.

Note: [1] Connector X4/5 is formed from two 8-way connectors treated as a single 16-way
connector.
[2] The solder bridge pads, numbered 1 to 6, next to the bit-switch can be used to alter the
step/direction, step-up/step-down and the standby settings of each axis. See the Control
section.

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. Motor connections will need to be determined from the
data sheet of the motor. Wire colour or terminal markings identify the connections,
depending upon the make of the motor.

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. The single-ended version does not have the same noise immunity, but offers
the choice of a simple control interface.
Table A-2 lists the signal functionality for a differential input drive.

Shutdown
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). The Fault output can be reset by toggling (turning OFF and ON)
the axis Shutdown input. If a supply rail fault occurs, all three axes Fault outputs will signal a
fault. In this situation you may either reset each individual axis or cycle the power to the
drive to clear the fault indication.
Composite Fault Output
This output is used to alert a controller that a fault has occurred on one or more axes of the
drive.
Zero Phase Outputs
The individual Zero Phase outputs 1, 2 & 3 indicate the zero phase condition for each
individual axis, that occurs once every electrical cycle or 50 times per mechanical revolution
of the motor.
LED Indicators Function
The bi-coloured LED indicates the state of the drive, as shown in Table A-4.

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.
Bit-switch settings only take effect following a power cycle or by de-energising and re-
energising the 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.
