5 DATA USED FOR POSITIONING CONTROL
Pr.119 Feed forward gain
Set the feed forward gain factor for position control.
When the setting is 0%, feed forward control is not performed.
When the setting is 100%, droop pulses are not generated during constant-speed
operation.
However, if sudden acceleration/deceleration is made, overshoot increases. (The
guideline of the acceleration/deceleration time at 100% is 1s or more.)
POINT
When setting this parameter, always set "
2".
Pr.120 In-position range
Set the droop pulse range in which the in-position output is provided to the AD75.
Set this parameter in the unit of "
Example) When setting 10 m as the in-position range at the ballscrew lead of
10mm and the feedback pulse of 8192 pulse, set the value indicated by
the following expression.

Pr.121 Solenoid brake output
Set a time delay from when the solenoid brake interlock signal (MBR)
turns OFF until the servo amplifier shuts OFF the base circuit.
