*1.Recommended products are listed in 4-3 Wiring
Conforming to EMC Directives.
*2.Recommended relays: MY Relays by OMRON
(24-V)
For example, MY2 Relays by OMRON can be
used with all G5-series Servomotors with Brakes
because itsrated inductive load is 2 A (24 VDC).
*3.There is no polarity on the brake.
*4.Provide auxiliary contacts to protect the system
with an external sequence so that a Servo ON
state will not occur due to deposition in the
Dynamic Brake Resistor.
*5.Use an external Dynamic Brake Resistor of
1.2 Ω, 400 W.
*6.Install an external protective device, such as a
thermal switch. Monitor the temperature of the
external Dynamic Brake Resistor.
*7. Wire the circuit so that the voltage between DB1
and DB2 is 300 VAC or less or 100 VDC or less.
Use a separate power source to supply power to
CN1.
*8. Insert a surge suppressor if you use AC power.
