VCO
Analog speed command offset:
Used to set the offset voltage of the analog speed
command (VC). When automatic VC offset is used, the
automatically offset value is set to this parameter.
(See section 2-3-3.)
The initial value is the value provided by the automatic VC
offset function before shipment at the VC-LG voltage of 0V.
Depends
on servo
amplifier.

S
mV
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.
(See section 2-3-3.)
The initial value is the value provided by the automatic VC
offset function before shipment at the VLA-LG voltage of 0V.

Analog torque command offset:
Used to set the offset voltage of the analog torque
command (TC).

Analog torque limit offset:
Used to set the offset voltage of the analog torque limit
(TLA).

Analog monitor 1 offset:
Used to set the offset voltage of the analog monitor 1
output (MO1).

Analog monitor 2 offset:
Used to set the offset voltage of the analog monitor 2
output (MO2).

MBR
Electromagnetic brake sequence output:
Used to set the delay time between when the electro-
magnetic brake interlock signal (MBR) switches off and
when the base circuit is shut off.

GD2
Ratio of load inertia moment to servo motor inertia moment:
Used to set the ratio of the load inertia moment to
the servo motor inertia moment. Note that when auto
tuning is selected, the result of auto tuning is auto-
matically set.

PG2
Position loop gain 2:
Used to 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.

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.

Speed loop gain 2:
Set this parameter when vibration occurs on machines of
low rigidity or large backlash. Higher setting increases the
response level but is liable to generate vibration and/or noise
