PA01 Control mode
Turn off the power and then on again after setting the
parameter to validate the parameter value.
Select the control mode.
This parameter is set as "_ _ 0_" in the initial setting.

Control mode selection
0: Rotary servo motor
0000h PA01 Operation mode
Select an operation mode.
_ _ _ x:
For manufacturer setting 0h
_ _ x _:
Operation mode selection
0: Standard control mode
Setting other than above will result in [AL. 37 Parameter
error].
For MR-J4W2-0303B6 servo amplifiers, this digit cannot
be used other than the initial value.

Compatibility mode selection
To change this digit, use an application software "MR-
J4(W)-B mode selection". When you change it without
the application, [AL. 3E Operation mode error] will occur.
Set the digit as common setting.
0: J3 compatibility mode
1: J4 mode 1h
PA02 Regenerative option
Turn off the power and then on again after setting the
parameter to validate the parameter value.
Wrong setting may cause the regenerative option to burn.
If the regenerative option selected is not for use with the
servo amplifier, [AL. 37 Parameter error] occurs.
The MR-RB3B can be used with the servo amplifier
whose software version is B3 or later.
Set this parameter when using the regenerative option.
For MR-J4W2-0303BN6 servo amplifiers, this digit cannot
be used other than the initial value.
_ _ x x:
Selection of regenerative option
00: Regenerative option is not used (built-in regenerative
resistor is used)
0D: MR-RB14
0E: MR-RB34

0000h PA02 Regenerative option
Select a regenerative option.
Incorrect setting may cause the regenerative option to
burn.
If a selected regenerative option is not for use with the
servo amplifier, [AL. 37 Parameter error] occurs.
For MR-J4W2-0303B6 servo amplifiers, this digit cannot
be used other than the initial value.
_ _ x x:
Regenerative option selection
00: Regenerative option is not used. (Built-in
regenerative resistor is used.)

PA03 Absolute position detection system
Turn off the power and then on again, or reset the
controller after setting the parameter to validate the
parameter value.
This parameter cannot be used in the speed control
mode.
Set this parameter when using the absolute position
detection system in the position control mode.
0 0 0 x:
Selection of absolute position detection system
0: Used in incremental system
1: Used in absolute position detection system 0000h PA03 Absolute position detection system
Set this parameter when using the absolute position
detection system. The parameter is not available in the
speed control mode and torque control mode.

0: Disabled (used in incremental system)
1: Enabled (used in absolute position detection system) 0h
