2.6.4 Regenerative Resistors and Brake Power Supply Units
* 1. For the optional JUSP-RA04 Regenerative Resistor Unit.
* 2. For the optional JUSP-RA05 Regenerative Resistor Unit.
* 3. For the optional JUSP-RA18 Regenerative Resistor Unit.
* 4. For the optional JUSP-RA19 Regenerative Resistor Unit.
* 5. Be careful when connecting the power supply for 24 VDC brake to the local power supply. The local
power supply cannot apply the overvoltage such as surge to the output side, and the output side may
be damaged even if the voltage is applied. Never fail to use the surge suppressor.
Note: 1. If the SERVOPACK cannot process the regenerative power, an external regenerative resistor is
required. Refer to 5.8.6 External Regenerative Resistor, 5.8.7 Regenerative Resistor Unit, and
6.5 Connecting Regenerative Resistors.
