3.4Encoder Connector CN2

Integrated within the servo motor is an incremental encoder with 2,500PPR and commutation signal.

When power is first applied to the servo drive, control algorithms detect the motor's rotor position through imbedded sensors in the motor within 500msec approximately.

Feedback to the amplifier of the UVW signals for commutation is via the ABZ encoder signal wires. Following rotor position sensing the amplifier automatically switches to encoding for commutation control.

The 2500PPR encoder is automatically multiplied to 10000PPR by X4 logic for increased control accuracy.
