Analog speed command offset:
Depends
Used
to
set the offset voltage
of
the analog speed command
(VC).
onservo
When automatic
VC
offset is used, the automatically offset value is
amplifier
set to this parameter.
The initial value is the value provided by the automatic
VC
offset
function before shipment at the
VC-LG
voltage of
OV.
Analog speed limit offset:
Used
to
set the offset voltage of the analog speed limit
(VLA).
When
automatic
VC
offset is used, the auto-matically offset value is set
to
this parameter.
The initial value is the value provided by the automatic
I’C
offset
function before shipment at the
TU-LG
voltage
of
OV.

TLO
Analog torque command offset:
0
Used to set the offset voltage of the analog torque command
(TC).
.halog torque limit offset:
Used to set the offset voltage of the analog torque limit
(TLA).

hfBR Electromagnetic brake sequence output:
100
Used to set the delay time
(Tb)
between electromagnetic brake
operation and the base drive circuit is shut-off.

I
GD2 Ratio of load inertia moment to servo motor inertia moment:
70
Used to set the ratio of the load inertia moment
to
the servo motor
shaft inertia moment. When auto tuning
is
selected, the result of
auto tuning is auto-matically set.
35
PG2 Position loop gain 2:
30
Used to set the gain of the position loop.
Set this parameter to increase the position response to level load
disturbance. Higher setting increases the response level but is liable
to generate vibration and/or noise.
When auto tuning
is
selected, the result of auto tuning is
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 selected, the result of auto tuning is
216
automatically set.
37
VG2 Speed loop gain 2:
714
Set this parameter when vibration occurs on machines of low rigidity
or large backiash. Higher setting increases the response level but
is
liable to generate vibration and/or noise.
When auto tuning is selected, the result of auto tuning is
automatically set.
38
\.?C
Speed integral compensation
20
Used to set the integral time constant of the speed loop.
When auto tuning is selected, the result
of
auto tuning is
automatically set.
