MR-J3-_A_
No.
Name and function
PC11 Internal speed command 7
Used to set speed 7 of internal speed commands.
Internal speed limit 7
Used to set speed 7 of internal speed limits.
PC12 Analog speed command maximum speed
Used to set the speed at the maximum input voltage
(10 V) of the analog speed command (VC).
When "0" is set, the analog speed command
maximum speed would be the rated speed of the
servo motor connected.
The speed is as indicated below for motorless
operation of test operation.
Servo amplifier capacity
100 V class 100 W to 400 W
100 W to 750 W
200 V class
1 kW to 37 kW
400 V class 600 W to 55 kW
Analog speed limit maximum speed
Used to set the speed at the maximum input voltage
(10 V) of the analog speed limit (VLA).
Set "0" to select the rated speed of the servo motor
connected.
PC13 Analog torque command maximum output
Used to set the output torque at the analog torque
command voltage (TC = ±8 V) of +8 V on the
assumption that the maximum torque is 100 [%]. For
example, set 50 to output (maximum torque ×
50/100) at the TC of +8 V.

Name and function
PC11
Same as MR-J3
Internal speed command 7
Set the speed 7 of internal speed commands.
Setting range: 0 to permissible instantaneous speed
Internal speed limit 7
Set the speed 7 of internal speed limits.
Setting range: 0 to permissible instantaneous speed
PC12
Same setting as MR-J3
Analog speed command - Maximum speed
Set the speed of servo motor at the maximum
voltage (10 V) input to VC (Analog speed
command).
When "0" is set, the rated speed of the connected
servo motor is used.
When you input a command value of the permissible
speed or more to VC, the value is clamped at the
permissible speed.
Setting range: 0 to 50000
Analog speed limit - Maximum speed
Set the speed of servo motor at the maximum
voltage (10 V) input to VLA (Analog speed limit).
When "0" is set, the rated speed of the connected
servo motor is used.
When you input a limit value of the permissible
speed or more to VLA, the value is clamped at the
permissible speed.
Setting range: 0 to 50000
PC13
Same as MR-J3
Analog torque command maximum output
This is used to set the output torque at the analog
torque (TC = ±8 V) of +8 V on the assumption that
the maximum torque is 100.0%.
For example, set 50.0.
The maximum torque ×
If a value equal to or larger than the maximum
torque is inputted to TC, the value will be clamped at
the maximum torque.
Setting range: 0.0 to 1000.0
