EZ4AXIS
You will need:
Your EZStepper® Controller/Driver
PC with USB port
Power supply, 9 to 30V. For first-time EZStepper users
we recommend a current-limited power supply to
protect against miswiring.
Appropriate motor (refer to data sheet for product)
Crimp tool (recommended): T-handle crimp tool,
Digikey part A9982. Otherwise, soldering equipment.
(Note: alternative connectors may be used, as
described in Application Note 131021, Mating
Connectors for Headers.)
Small Philips screwdriver for operating address switch
on board
If troubleshooting is required: ohmeter, oscilloscope
If using USB Port connection, matching USB cable
(provided in starter kit)
Precautions
Observe all electrostatic discharge precautions to avoid
damaging circuit boards.
Allow at least 0.1" air gap when bolting EZStepper to
mounting plate, for cooling.
Use 4-40 round standoffs to bolt EZStepper to
mounting plate, NOT hex (hex standoffs will touch
components). Alternatively, use heat sink available
from AllMotion (order number EZ4AXIS-SINK).
DO NOT disconnect motor wires while power is on, to
avoid damage to circuit board.
DO NOT place exposed circuit boards on metal
surface when powered (to prevent shorts).
Avoid bundling encoder or IO wires with motor power
wires, as this may cause noise pickup from motor
wires. If bundling is necessary, put motor wires in a
separate shielded twisted-pair cable.
-For 10' or longer, shield each IO line individually.
-If using ribbon cable, add grounds between signal
wires and motor wires.
Start with power supply OFF.
1. Download and install the EZCommander™ application from
www.allmotion.com/support/EZStepper Windows Application. (Use your own
terminal program for Mac or Linux. Some instructions may not apply.)
2. Download and install appropriate USB driver from
www.allmotion.com/support.
3.
Ensure power is OFF.
Connect power supply to the EZ4AXIS.
(See Wiring Note also.)
4. Turn power ON. Confirm that green Life LED slowly blinks. If not, look for
bad power connection.
5. Set address switch firmly to number 1 with Philips screwdriver.
6. Cycle power OFF/ON if address switch was moved in preceding step.
7.
With USB cable to PC unplugged:
Start the EZCommander application (see
other side of sheet for instructions if needed). Click ‘Settings,” then “Re-scan
Ports.” Note available ports, then click “OK.”
8. Connect EZ4AXIS to a PC USB port with the cable (included in starter kit).
9. In EZCommander, click “Settings,” then “Re-Scan Ports.” Select the new port
that becomes available, and click “OK.” If no new port appears, a problem
with the USB driver is indicated. Re-install the driver for your system.
10. In EZCommander, click “Send String
0”
to issue the command “/1&.” Confirm
return message showing product name and firmware version. If return message
says “No EZStepper Detected,” troubleshoot communications (page 3) before
connecting motor.
11.
With power OFF
, connect stepper motor to Axis 1 as shown in the diagram.
(See Wiring Note also.)
12. Turn power ON.
13. In EZ Commander, issue the command
“/1A1
000
A
0
R
.”
Confirm that
motor rotates back and forth.
14.
With power OFF
, connect stepper motors to the remaining three motor
connectors as shown for Axis 1 in the diagram.
15. Turn power ON.
16. issue the command “/1A1
000
,1

motors move simultaneously.
You’re on your way!

Troubleshooting:

CAUTION!
Do not connect or disconnect
motor with power applied.
Unplugging of or intermittant connection to an
inductive load causes a high-voltage spark,
which will damage the driver.

Wiring Note
Always wire to the mating connectors supplied
on circuit board. Use crimp tool if you have it,
or else solder. (DO NOT solder to circuit board;
damage is likely. Also, DO NOT press in with a
screwdriver, because this makes unreliable
connections.)
