*1. A recommended product is listed in 4-3,
Wiring Confirming to EMC Directives.
*2. Recommended relay: MY relay by
OMRON (24-V) For example, MY2 relay
by OMRON can be used with all G5-series
motors with brakes because its rated
induction load is 2 A (24 VDC).
*3. There is no polarity on the brakes.
*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 temperature fuse. Monitor the
temperature of the external Dynamic Brake
Resistor.
