Defining Analog Velocity
This procedure assumes that you have wired your 1394 Analog Servo
System and have completed the procedures in the following sections
of this chapter:
• Removing and Re-Applying Power
• Setting Up at the System Level
• Setting Up Analog Test Points
• Defining Your Motors
These procedures continue from step 4 of Defining a Reference
Source for Your Axes.
To define analog velocity:
1. When the Ax:Mode Sel Anlg Vel message appears, press ENTER.
A message similar to the following appears:
2. Press SEL. The cursor moves to the bottom line.
3. Press either the up or down arrow until the parameter number that
you want to use for the rpm/volt gain appears.
4. Press ENTER. The system records your choice and the cursor
moves to the top line.
5. Press ENTER. A message similar to the following appears:
6. On the system module’s input board, short the velocity reference
inputs (AxVref+ and AxVref-) to null the analog velocity offset.
7. Press ENTER. A message similar to the following appears:
8. Remove the short on the velocity reference inputs.
9. Go to Defining Limits.
If you selected: Go to:
Anlg Vel Defining Analog Velocity.
Ana Torq Defining Analog Torque.
Dig Vel Defining Digital Velocity.
