MR-J2S-_A_
No. Name and function
29 Analog speed command offset
Used to set the offset voltage of VC (Analog speed
command).
For example, if switching on ST1 (forward rotation start)
with 0 V applied to VC causes CCW rotation, set a
negative value.
When VC automatic offset is used, the automatically
offset value is set to this parameter.
The initial value is provided before shipment by the VC
automatic offset function on condition that the voltage
between VC and LG is 0 V.
Setting range: -999 to 999 mV
Analog speed limit offset
Used to set the offset voltage of VLA (Analog speed
limit).
For example, if switching on RS1 (forward rotation
selection) with 0 V applied to VLA causes CCW rotation,
set a negative value.
When VC automatic offset is used, the automatically
offset value is set to this parameter.
The initial value is provided before shipment by the VC
automatic offset function on condition that the voltage
between VLA and LG is 0 V.
Setting range: -999 to 999 mV
30 Analog torque command offset
Used to set the offset voltage of TC (Analog torque
command).
Setting range: -999 to 999 mV
Analog torque limit offset
Used to set the offset voltage of TLA (Analog torque
limit).
Setting range: -999 to 999 mV
31 Analog monitor 1 offset
Used to set the offset voltage of Analog monitor 1 (MO1).
Setting range: -999 to 999 mV
32 Analog monitor 2 offset
Used to set the offset voltage of Analog monitor 2 (MO2).
Setting range: -999 to 999 mV
33 Electromagnetic brake sequence output
Used to set the delay time (Tb) between MBR
(Electromagnetic brake interlock) OFF and base circuit
shut-off.
Setting range: 0 to 1000 ms
34 Load to motor inertia ratio
Used to set the motor inertia ratio to the servo motor
shaft inertia moment.
When auto tuning mode 1 or interpolation mode is
selected, the result of auto tuning is automatically used.
In this case, the value varies between 0 and 1000.
Setting range: 0 to 3000; Unit: x0.1

amplifier.
The initial value is provided before shipment by the
VC automatic offset function on condition that the
voltage between VC and LG is 0 V.
For example, when the motor rotates by switching
on ST1 (forward rotation start) with 0 V applied to
VC, set an offset voltage.
Setting range: -9999 to 9999 mV
Analog speed limit offset
Used to set the offset voltage of VLA (Analog speed

The initial value is provided before shipment by the
VC automatic offset function on condition that the
voltage between VC and LG is 0 V.
When the motor rotates by switching on RS1
(Forward rotation selection) with 0 V applied to VLA,

Setting range: -9999 to 9999 mV
Analog torque limit offset
Used to set the offset voltage of TLA (Analog torque
limit).
Setting range: -9999 to 9999 mV
0 PC39 Analog monitor 1 offset
Used to set the offset voltage of MO1 (Analog
monitor 1).
Setting range: -9999 to 9999 mV
0 PC40 Analog monitor 2 offset
Used to set the offset voltage of MO2 (Analog
monitor 2).
Setting range: -9999 to 9999 mV
100 PC16 Electromagnetic brake sequence output
Used to set the delay time (Tb) between MBR
(Electromagnetic brake interlock) OFF and base
circuit shut-off.
Setting range: 0 to 1000 ms
Set the same value as for MR-J2S-_A_.
70 PB06 Load to motor inertia ratio
When auto tuning mode 1 is selected, the auto
tuning result is automatically used.
Setting range: 0.00 to 300.00; Unit: x1.0
Note that the setting unit is different from that for
MR-J2S-_A_.
When setting a value manually, set a value 0.1 x the
MR-J2S-_A_ setting value.
