Step 3: Configure the Drive and Connect the Motor and Encoder to the Drive
This section covers the minimum drive settings and connections to allow the motor to move. Refer to
the drive manual for additional information about drive parameters and signal information.
1.
Power on the drive and configure the drive for position control mode. These parameters differ
depending on the drive. Refer to the drive manual for information about how to set drive
parameters.
•
Mitsubishi MR-J2
—Set parameter P 21 to 1 (signed pulse train).
•
Mitsubishi MR-J3
—Set parameter PA 01 to 0 (position control) and PA 13 to 1 (step and
direction). You may also need to set parameter PA 05 (pulses per rev) to the appropriate setting
for your encoder.
2.
Ensure that the drive encoder output pulses and electronic gear parameters are set to the default
values:
Mitsubishi MR-J2
a.
Set parameter P 27 to 4000 pulses per rev. If you change this from the default value, you must
also change the value specified for the encoder
Counts per rev
Software Installation and Configuration
section.
b.
Set parameter 3 and parameter 4 to 1. This disables any electronic gearing settings.
Mitsubishi MR-J3
a.
Set parameter PA 15 to 4000 pulses per rev. If you change this from the default value, you must
also change the value specified for the encoder
Counts per rev
Software Installation and Configuration
section.
b.
Set parameter PA 05 to 0. This disables the number of command input pulses per servo motor
revolution parameter.
c.
Set parameter PA 06 and parameter PA 07 to 1. This disables any electronic gearing setting.
3.
Connect the motor and encoder to the drive. Refer to the documentation specific to your drive for
motor and encoder connection information.
Tip
An incorrectly connected encoder may cause NI SoftMotion to return error
-77076
(
NIMCDM_driveReadyNotActiveError
). Verify the encoder connections if you see this error.
4.
Connect the drive power. Refer to the drive documentation for power connections and
specifications.
5.
Apply power to all the hardware once all connections are made and continue to the next section.
Software Installation and Configuration
This section covers installing and configuring the software for the NI 9512 C Series drive interface
module. It assumes that all required software from the
section is installed.
Step 1: Install Software on and Configure the NI RT Controller
Complete the following steps to configure the controller and install software on it.
Note
The Measurement & Automation Explorer (MAX) user interface may not match these steps
exactly depending on which version of MAX you are using.
1.
Launch MAX on the development computer by clicking the MAX icon on the desktop, or by
selecting
Start»All Programs»National Instruments»Measurement & Automation
.
2.
Select the controller under
Remote Systems
in the
Configuration
pane. If you do not see the
controller, you may need to disable the firewall on the development computer. Go to
ni.com/info
and enter
RIOMAXTroubleshoot
for more information.
