*1. A recommended product is listed in 4-3,
Wiring Confirming to EMC Directives.
*2. Recommended relay: MY relay by
OMRON (24-V)
MY2 relay by OMRON can be used for
a rated inductive load of 2 A (24 VDC).
*3. 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.
*4. Use an external Dynamic Brake
Resistor of 4.8 Ω, 400 W.
*5. Wire the circuit so that the voltage
between DB1 and DB2 is 400 VAC or
less.
Install an external protective device,
such as a temperature fuse. Monitor the
temperature of the external Dynamic
Brake Resistor.
