Note 1. Recommended product in 3-2-4 Wiring for Noise Resistance.
2. Recommended relay: MY Relay (24 V), by OMRON.
3. For 400-W and 750-W Servo Drivers, an R88A-RR22047S
External Regeneration Resistor may be connected. Connect if the
regenerative energy exceeds the individual Servo Driver's
regenerative capacity. Also, connect a thermal switch output so that
the power supply will be turned OFF when open.
4. If an External Regeneration Resistor is to be connected to a 750-W
Servo Driver, 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.
