Scaling Acceleration (Torque Motors Only)

This command sets the scaling acceleration value for a stage equipped
with a torque motor. That is the maximum acceleration acceptable by the
mechanical system required by the controller when the maximum tension
(±10 V on the output of the DAC) is applied on the driver board.

Encoder Resolution

This parameter defines the physical travel of the motion device that corre-
sponds to one encoder count. It represent the resolution of the system and
must reflect the real physical value (theoretical value, excluding all errors).
This parameter can be used to correct for a linear error in the motion
device's absolute position accuracy. See the Motion Control Tutorial sec-
tion for more details.
For the PP families, the Motor and the Encoder Increment can be changed
separately, on condition that:
• If encoder resolution ≥ motor resolution: OK.
• If encoder resolution < motor resolution: OK but Motor Resolution
= new encoder resolution.
If you need to correct the encoder increment setting, press the
to modify the current value. Use the numeric keypad to enter the correct
value. Press
menu.
It is recommended that this value not be altered.
