5 Interfaces – Pinouts and Wiring
5.1 Power Interface
The power interface serves to connect the AC power supply to the CD3E.
The interface is also used to supply power to the motor phases.
In addition, it provides the connection to an external regenerative power resistor to dissipate
energy generated by the motor, typically during deceleration.
Make sure the main voltage rating matches the drive specification. Applying incorrect
voltage may cause drive failure.
Do not apply power until all hardware connections are complete.
Prevent inrush surge: Bus power (L1-L2): After switching off bus power, wait 1 minute
before switching on again.
