Parameter Operation
MELSERVO J2-Super 4 - 17
Number Symbol Initial value Unit Setting range
14 VG1 177 rad/s 20–5000
Speed control gain1
If auto tuning 1 or 2 (parameter 8) or interpolation mode is selected, then this parameter will optimise itself
automatically. If auto tuning or interpolation mode is de-selected, then this parameter should not be changed.
Higher setting increases the response level but is liable to generate vibrations.
15 PG2 35 rad/s 1–1000
Position control gain 2
Set this parameter to increase position response to load disturbance. Higher setting increases the response level but
is liable to generate vibrations.
If auto tuning 1 or 2, manual setting method or interpolation mode (pr. 8) is selected, then this parameter will
optimise itself automatically. If auto tuning 1 or 2, manual setting method or interpolation mode is de-selected, then
the position control loop must be set via this parameter.
16 VG2 817 rad/s 20–5000
Speed control gain 2
Set this parameter to increase position response to load disturbance. Higher setting increases the response level but
is liable to generate vibrations.
If auto tuning 1 or 2 or interpolation mode (pr. 8) is selected, then this parameter will optimise itself automatically. If
auto tuning 1 or 2 or interpolation mode is de-selected, then the revolution speed control loop must be set via this
parameter.
17 VIC 48 ms 1–1000
Speed integral compensation
If auto tuning 1 or 2 or interpolation mode (pr. 8) is selected, then this parameter will optimise itself automatically.
