		Name and function			Initial	Unit	Setting	Control
					value		range	mode
In-position range					100	pulse	0	P
Used to set the in-position (INP) signal output range in the command							to
pulse increments prior to electronic gear calculation.							10000
Position loop gain 1					35	red/s	4	P
Used to set the gain of position loop 1.							to
Increase the gain to improve trackability in response to the position							2000
command.
The result of auto tuning is automatically provided when auto tuning
is selected.
Position command acceleration/deceleration time constant					3	ms	0	P
(position smoothing)							to
Used to set the time constant of a low pass filter in response to the							20000
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
	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.
