Note 1. The bus bars on L+ and L- for connecting the resistance regeneration converter unit to the drive unit are standard accessories.
In the actual connection, the resistance regeneration converter unit is closely mounted to the drive unit.
2. For the power supply specifications, refer to "Part 6: Common Reference Material".
3. For specifications of the cooling fan power supply, refer to "Servo Motor Instruction Manual (Vol. 3)".
4.
An bus voltage may drop, depending on the main circuit voltage and operation pattern, causing a dynamic brake deceleration
during a forced stop deceleration. When dynamic brake deceleration is not required, delay the time to turn off the magnetic
contactor.
5. If the wire used for L11 and L21 is thinner than the wire used for L1, L2, and L3, use a molded-case circuit breaker. (Refer to
Section 7.3 in this part.)
