*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. When using an externally connected
Dynamic Brake Resistor, remove the short
bar from between DB3 and DB4.
*5. 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.
*6. A Dynamic Brake Resistor of 2 Ω, 180 W
is built in. If the capacity is insufficient, use
an external Dynamic Brake Resistor of 1.2
Ω, 400 W. Do not use the built-in resistor
and an external resistor at the same time.
*7. Install an external protective device, such
as a temperature fuse. Monitor the
temperature of the external Dynamic Brake
Resistor.
