For Metric Ballscrews the target value is 302.
For Inch Ballscrews and Rotary tables the target value is 595.
Use the SETP command to check the current Ballscrew Type if you're not sure about
which ballscrew you may have.
The goal of the adjustment is to match the other axes so the system is dynamically
balanced with all the XYZ axes. It's not required to be exactly set the value, it can be; +-
10 counts, in most cases. However it does somewhat affect the contouring accuracy; the
closer the better.
7) Press the SLIDE HOLD key and adjust the Balance potentiometer of the amplifier to read
a following error between +1 and - 1.
8) Press the START key and the program will start again. Verify that the following error is
still correct starting from step 5 above.
9) Press the SLIDE HOLD key to stop the machine. Press the MANUAL key and then type
SETCS and HO, to send the machine home. Adjustment of the amplifier is complete.

Note for Rotary Scales:
When disconnecting the rotary scale to adjust the amplifier, you must verify the SETP
axis ratio has the correct mechanical ratio. For example the TR65 B axis normally has
the SETP set to a 180 to 1 ratio (when using the scale). It must be temporally set to 90:1
to adjust the amplifier without the scale feedback. Using the SETP command, set the B
axis ration back to 180 to 1 after adjusting the amplifier. Changing the ratio requires
cycling the power to the machine (off/on).
