No. Name and function
PA02 Regenerative option
This parameter is made valid when power is switched off,
then on after setting.
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.
Set this parameter when using the regenerative option,
brake unit, power regeneration converter, or power
regeneration common converter.
0 0 x x:
Selection of regenerative option
00: Regenerative option is not used
・For the servo amplifiers of 100 W, a regenerative
resistor is not used.
・For servo amplifier of 0.2 kW to 7 kW, built-in
regenerative resistor is used.
・Supplied regenerative resistors or regenerative option
is used with the servo amplifier of 11 kW to 22 kW.

This parameter is made valid when power is switched off,
then on after setting, or when the controller reset has
been performed.
Set this parameter when using the absolute position
detection system.
