Dynamic brake interlock
Note 1. Terminals 13, 14 are normally open contact outputs. If the external dynamic brake is seized, terminals 13, 14 will open.
Therefore, configure up an external sequence to prevent servo-on.
2. When using the servo amplifier of 11k to 22kW, make sure to connect P
When using the power factor DC reactor, refer to section 14.11.
3. Assign the dynamic brake interlock (DB) in the parameters No.PD09 PD10 PD11.
4. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class in 400V class servo amplifiers.
5. Refer to section 1.2 for the power supply specification.
6. The power supply voltage of the inside magnet contactor for 400V class external dynamic brake DBU-11K-4 and DBU-22K-4 is
restricted as follows. When using these external dynamic brakes, use them within the range of the power supply.
7. Configure the circuit which shuts off main circuit power with external sequence at forced stop (EMG) off.
