5 INP In-position range
Used to set the in-position (INP) output range in the command pulse
increments prior to electronic gear calculation.
For example, when you want to set 100 m when the ball screw is
directly coupled, the lead is 10mm, the feedback pulse count is 131072
pulses/rev, and the electronic gear numerator (CMX)/electronic gear
denominator (CDV) is 16384/125 (setting in units of 10 m per pulse),
set "10" as indicated by the following expression.

6 PG1 Position control gain 1
Used to set the gain of position loop.
Increase the gain to improve track ability in response to the position
command.
When auto turning mode 1,2 is selected, the result of auto turning is
automatically used.

P
Position command acceleration/deceleration time constant
(position smoothing)
Used to set the time constant of a low-pass filter in response to the
position command.
You can use parameter No. 55 to choose the primary delay or linear
acceleration/deceleration control system. When you choose linear
acceleration/deceleration, the setting range is 0 to 10ms. Setting of
longer than 10ms is recognized as 10ms.
POINT
7 PST
When you have chosen linear acceleration/
deceleration, do not select control selection
(parameter No. 0) and restart after instantaneous
power failure (parameter No. 20). Doing so will
cause the servo motor to make a sudden stop at the
time of position control switching or restart.

Example: When a command is given from a synchronizing detector,
synchronous operation can be started smoothly if started
during line operation.
