Note 1 Terminals 13, 14 are N/O contact outputs. When the dynamic brake has stuck, terminals 13, 14 are opened. Therefore, configure

up the circuit to prevent servo-on in the external sequence.

2. For converter unit and servo amplifier 400 V class, stepdown transformer is required for coil voltage of magnetic contactor more

than 200 V class.

3. Assign the dynamic brake interlock (DB) in parameter No.PD07 to PD09.

4. Refer to section 13.1.3 for the power supply specifications.

5. Make up a sequence that turns off the drive unit forced stop (EM1) and the converter unit forced stop (EM1) at the same time.
