pulse increments prior to electronic gear calculation.

6 PG1 Position loop gain 1
Used to set the gain of position loop.
Increase the gain to improve trackability 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.
