*1. A recommended product is listed in 4-3,
Wiring Confirming to EMC Directives.
*2. Recommended relay: MY relay by
OMRON (24-V)
MY2 relay by OMRON can be used for
a rated inductive load of 2 A (24 VDC).
*3. When using an externally connected
Dynamic Brake Resistor, remove the
short bar from between DB3 and DB4.
*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. 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. Do not
use the built-in resistor and an external
resistor at the same time.
*6. Wire the circuit so that the voltage
between DB1 and DB2 is 400 VAC or
less. Install an external protective
device, such as a temperature fuse.
Monitor the temperature of the external
Dynamic Brake Resistor.
