(Note 6)
Note 1. L+ and L- conductors to connect the converter unit and drive unit are standard accessories. The converter unit and drive unit
are installed more closely together than they are shown in this diagram.
2. For the power supply specifications, refer to Part 7 "Common Reference Material".
3. For the power supply specifications of the cooling fan, refer to the Servo Motor Instruction Manual (Vol. 3).
4. Bus voltage decreases according to the voltage and operation pattern of the main circuit, and there may be a shift in dynamic
brake deceleration during forced stop deceleration. If dynamic brake deceleration is not desired, delay the time to turn off the
electromagnetic contactor.
5. Install an overcurrent protection device (molded-case circuit breaker, fuse, or others) to protect the branch circuit. (Refer to
section 5.3.)
6. The converter unit and the drive unit can be connected to the control circuit power supply (L11/L21) by daisy chain. Refer to
section 5.2 for the wire size and the selection of the overcurrent protection device.
