To use the built-in regenerative brake resistor of the servo amplifier, connect the
wiring across P-D of the power supply connector (CNP1).
When using the regenerative brake option, always remove the wiring from across
P-D and connect the regenerative brake option across P-C.
Refer to Section 13.1.1 for details.
Protective earth (PE)
Connect this terminal to the protective earth (PE) terminals of the servo motor
and control box for grounding.
