2.
Ensure that the drive encoder output pulses and electronic gear parameters are set to the default
values:
Panasonic Minas A
a.
Set parameter PA_r44 to 2500 pulses per rev. If you change this from the default value, you
must also change the value specified for the encoder counts per rev in
Software Installation and Configuration
section.
b.
Set parameters PA_r46, PA_r47, and PA_r4B to 10000 and parameter PA_r4A to 0. This sets
any electronic gearing to a 1:1 ratio.
Panasonic Minas A5
a.
Set parameter PR0.08 to 10000. This specifies the number of command pulses for one motor
revolution. If you change this from the default value, you must also change the value specified
for
Steps per rev

b.
Set parameter PR0.11 to 2500 pulses per rev. This specifies the number of encoder pulses per
revolution. If you change this from the default value, you must also change the value specified
for the encoder
Counts per rev
in
Step 3: Configure the NI 9512 C Series Module
of the
Software Installation and Configuration
section by multiplying the specified value by four.
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.
3.
Verify that the
Serial Number
in the
General Settings
section matches the serial number on the
device.
4.
If you do not want to format the disk on the controller, eliminating all installed software and files,
skip to step 14.
5.
Set the
Safe Mode
switch on the controller to the
On
position.
