For Step Motors
1. Set the controller I/O address (0x300 is the default) using dip switches.
2. Install the controller in the computer and connect the step drive.
3. Make sure the step drive is turned off.
4. Install the MEI software as described in the release note included with the distribution.
Start Motion Console (located in the
Motion Engineering
program group under
Start
).
5. Click
Add Controller
in the
Hardware Summary
window (go to PCI tab if using PCI/
DSP or CPCI/DSP controller). Enter the name of the controller in the dialog box. Mo-
tion Console uses the default address 0x300 for the controller.
6. Choose the axis in the
Axis List
and click the
Configure Axis
button. On the
Axis Con-
figuration
property page, configure the axis as
Stepper, Open Loop, Unipolar
. Click
Close
. If using an encoder, choose
Close Loop
and follow the instructions for phasing
encoders in “For Servo Motors” (begin with step 7).
Note!
The Step output rate defaults to Slow (0-20 kHz). For greater step output, choose Me-
dium (0-80 kHz), Fast (0-325 kHz) or Superfast (0-550 kHz) in the Axis Configuration
property page.
7. In the
Axis Operation
window, click the
Clear Position
and
Clear Fault
buttons.
8. Turn on the step drive. Verify all motor and drive wiring , turn on the drive, and enable
the drive. If the controller’s amp enable output is connected to the drive, you must
configure the amp enable logic in the
Dedicated I/O
window. Then click
Enable
in the
Amplifier
group in the
Axis Operation
window to activate the amplifier.
If the drive is in torque mode, you should be able to turn the motor shaft by hand. If
the drive is in velocity mode, the motor shaft should be stiff. For more information,
consult the amplifier manufacturer’s documentation.
9. Command a trapezoidal motion by entering
position
,
velocity
, and
acceleration
values
in the
Axis Operation
window.
10. Verify that the motor turns one rotation when the appropriate number of steps are com-
manded.
CPCI & PCI
Users:
Because the CPCI and PCI controllers comply with the PCI Plug and Play
specification, they do not have any on-board DIP switches. Instead, a soft-
ware utility (included with your distribution) checks the address that the
system assigns to the CPCI and PCI controllers. Refer to Section,
PCI on
page 2-10,
for more information.
