Note 1 For converter unit and servo amplifier 400V class, stepdown transformer is required for coil voltage of magnetic contactor more
than 200V class.
2. Assign the dynamic brake interlock (DB) in parameter No.PD13 to PD16 and PD18.
3. Refer to section 15.1.3 for the power supply specifications.
4. Make up a sequence that will concurrently turn off the Emergency stop (EMG) of the drive unit and the Forced stop (EM1) of the
converter unit, and shut off the main circuit power supply by the external sequence.
