CHAPTER 10 PERIPHERAL EQUIPMENT
To connect the optional external regenerative resistor
Perform the wiring and set the parameters shown below so that the servo system is shut off upon
activation (the contact was open) of the thermistor built in the external regenerative resistor.
Wiring of thermistor output of external regenerative resistor
Connect the wiring to one of the sequence inputs (CONT 1 to 5) of the servo amplifier.

Parameter setting
Allocate "34"(external regenerative resistor overheat) to PA3_01 to 05 (allocation to the
connected CONT signal).
Set PA2_65 (regenerative resistor selection) at "2" (external resistor).
* The external regenerative resistor will become excessively hot in the event of failure
of the regenerative transistor, possibly causing fire.
