*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
CN1
Brake Resistor, remove the short bar from
24VDC
XB
between DB3 and DB4.

*5. Provide auxiliary contacts to protect the system
(*2)
with an external sequence so that a Servo ON
2
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
(*4)
temperature fuse. Monitor the temperature of the
external Dynamic Brake Resistor.
*8. 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.
*9. When using AC power input, include a surge suppressor.
