Power supply system wiring
Power supply system wiring
• Check that the power supplied to the power input terminals (L11/L21) of the drive unit satisfies the defined specifications.
For the power supply specifications, refer to "Drive unit standard specifications" in User's Manual (Introduction).
Connecting drive units and servo motors
• Check that the power supplied to the power input terminals (L11/L21) of the drive unit satisfies the defined specifications.
For the power supply specifications, refer to "Drive unit standard specifications" in User's Manual (Introduction).
• Check that the CNP3A connector of the drive unit and A-axis servo motor, the CNP3B connector and B-axis servo motor,
and the CNP3C connector and C-axis servo motor are connected, and that the phases (U/V/W) of the drive unit power
outputs match with the phases (U/V/W) of the power inputs of each servo motor.
