*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.
*7. Wire the circuit so that the applied voltage between
DB1 and DB2 is 300 VAC/100 VDC or less.
Install a power supply separated from one that
supplies power to CN1.
*8. When using AC power input, include a surge
suppressor.
