No.
Name and function
PC37 Analog speed command offset
Used to set the offset voltage of the analog speed
command (VC).
For example, if CCW rotation is provided by
switching on forward rotation start (ST1) with 0 V
applied to VC, set a negative value.
When automatic VC offset is used, the
automatically offset value is 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 0 V.
Analog speed limit offset
Used to set the offset voltage of the analog speed
limit (VLA).
For example, if CCW rotation is provided by
switching on forward rotation selection (RS1) with 0
V applied to VLA, set a negative value.
When automatic VC offset is used, the
automatically offset value is set to this parameter.
The initial value is the value provided by the
automatic VC offset function before shipment at the
VLA-LG voltage of 0 V.
PC38 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).
PC39 Analog monitor 1 offset
Used to set the offset voltage of the analog monitor
(MO1).
PC40 Analog monitor 2 offset
Used to set the offset voltage of the analog monitor
(MO2).
PC43 For manufacturer setting
Do not change this value by any means.

Analog speed command offset
amplifier
Set the offset voltage of VC (Analog speed
command).
For example, if CCW rotation or positive direction
travel is provided by switching on ST1 (Forward
rotation start) while applying 0 V to VC, set a
negative value.
When automatic VC offset is used, the
automatically offset value is set to this parameter.
The initial value is provided before shipment by the
automatic VC offset function on condition that the
voltage between VC and LG is 0 V.
Setting range: -9999 to 9999
Analog speed limit offset
Set the offset voltage of VLA (Analog speed limit).
For example, if CCW rotation or positive direction
travel is provided by switching on RS1 (Forward
rotation selection) while applying 0 V to VLA, set a
negative value.
When automatic VC offset is used, the
automatically offset value is set to this parameter.
The initial value is provided before shipment by the
automatic VC offset function on condition that the
voltage between VLA and LG is 0 V.
Setting range: -9999 to 9999
0 PC38 Analog torque command offset
Set the offset voltage of TC (Analog torque
command).
Setting range: -9999 to 9999 mV
Analog torque limit offset
Set the offset voltage of TLA (Analog torque limit).
Setting range: -9999 to 9999 mV
0 PC39
Same as MR-J3
Analog monitor 1 offset
Set the offset voltage of MO1 (Analog monitor 1).
Setting range: -9999 to 9999 mV
0 PC40
Same as MR-J3
Analog monitor 2 offset
Set the offset voltage of MO2 (Analog monitor 2).
Setting range: -9999 to 9999 mV
0000h PC43 Error excessive alarm level
Set an error excessive alarm level.
You can change the setting unit with "Error
excessive alarm/error excessive warning level unit
selection" in [Pr. PC24].
Set this per rev. for rotary servo motors. Setting "0"
will be "3 rev", and setting over 200 rev will be
clamped with 200 rev.
Setting range: 0 to 1000
