Modifying User Units
The units displayed for any OMNIDRIVE may be modified using a PC with OMNI LINK software. The
PC Display Units help menu defines the various parameters displayed by OMNI LINK. Default settings
for Units are shown in Figure 8.12.
Changing the Display Units Settings
The following example changes the Label and Conversion Factor for the Position and Acceleration
parameters. This example assumes a 2000 line encoder (8000 pulses/revolution).
•
Position – from Counts to Motor Revolutions
•
Acceleration – from RPM/sec
2
to Revs/sec
2
1. Choose the
Drive Parameters
command icon from the Drive window and then select the
Units
button. The PC Display Units dialog appears with default settings as shown.
2. Select the Position Label cell, and change
counts
to
Mtr Revs
.
3. Select the Position Conversion Factor cell, and change
1000
to
0.125
.
Mathematically 1/8 (0.125) of a motor revolution is 1000 counts, given that the motor has a 2000
line (8000 count) encoder.
4. Select the Acceleration Label cell, and change
RPM/sec
to
Revs/sec
.
5. Select the Acceleration Conversion Factor cell, and change
1.
to
.016
.
Mathematically 1.6 x 10
-2
revs/sec
2
is 1 RPM/sec, given the motor has a 2000 line (8000 count)
encoder.
6. Choose
OK
to exit the PC Display Units dialog.
