Expansion parameters 1
35 PG2 Position loop gain 2
Set the gain of the position loop.
Set this parameter to increase position response to load
disturbance.
Higher setting increases the response level but is liable to
generate vibration and/or noise.
When auto tuning is valid, the result of auto tuning is
automatically set. Manual setting can be made by setting
"
4 " in parameter No. 2 (ATU).
35 rad/s 1 to 1000
36 VG1 Speed loop gain 1
Normally this parameter setting need not be changed.
Higher setting increases the response level but is liable to
generate vibration and/or noise.
When auto tuning is valid, the result of auto tuning is
automatically set. Manual setting can be made by setting
"
4 " in parameter No. 2 (ATU).
177 rad/s 20 to
8000
37 VG2 Speed loop gain 2
Set this parameter when vibration occurs on the machine of
low rigidity or large backlash.
Higher setting increases the response level but is liable to
generate vibration and/or noise.
When auto tuning is valid, the result of auto tuning is
automatically set.
817 rad/s 20 to
20000
38 VIC Speed integral compensation
Set the integral compensation of the speed loop.
Higher setting increases the response level but is liable to
generate vibration and/or noise.
When auto tuning is valid, the result of auto tuning is
automatically set.
48 msec 1 to 1000
39 VDC Speed differential compensation
Set the differential compensation.
Made valid when the proportion control signal is turned on.
980 0 to 1000
40 OVA For manufacturer setting 0
41 *DSS Position-speed command system selection
Set the direct designation system when the point table/position
command changing selection is a position command with the
MR-J2S-T01 used.
