1)MR-J2S-350B or less

Wiring is factory-connected across P-D (servo amplifier built-in regenerative brake resistor).

When using the regenerative brake option, always remove the wiring from across P-D and connect the regenerative brake option across P-C.

P, C, D		Regenerative brake option 2) MR-J2S-500B or more
			Wiring is factory-connected across P-C (servo amplifier built-in regenerative
			brake resistor).
			When using the regenerative brake option, always remove the wiring from
			across P-C and connect the regenerative brake option across P-C.
			Refer to Section 12.1.1 for details.
		Return converter	When using the return converter or brake unit, connect it across P-N.
	N		Do not connect it to the servo amplifier of MR-J2S-350B or less.
		Brake unit
			Refer to Sections 12.1.2 and 12.1.3 for details.
		Protective earth (PE)	Connect this terminal to the protective earth (PE) terminals of the servo motor
			and control box for grounding.
