*1. Recommended products are listed in 4-3
Wiring Conforming 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 8 Ω, 180 W is
built in. If the capacity is insufficient, use an
external Dynamic Brake Resistor of 4.8 Ω,
400 W.
*7. Wire the circuit so that the voltage between
DB1 and DB2 is 400 VAC or less. Install an
external protective device, such as a
thermal switch. Monitor the temperature of
the external Dynamic Brake Resistor.
