Note 1. Recommended product in 3-2-4 Wiring for Noise Resistance.
2. Recommended relay: MY Relay (24 V), by OMRON.
3. An R88A-RR22047S External Regeneration Resistor may be connected.
Connect if the regenerative energy exceeds the individual Servo Driver's
regenerative capacity. Also, connect the thermal switch
output so that the power supply will be turned OFF when open.
4. If an External Regeneration Resistor is to be connected,
remove the short bar between B2 and B3.
5. When either the main-circuit power supply or the control-circuit
power supply is OFF, the dynamic brake will operate.
