Encoder Connector CN2
Integrated within the servo motor is a 2500PPR incremental encoder.
When power is first applied to the servo drive, control algorithms detect the motor's rotor position through
imbedded sensors in the motor. 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 for increased control accuracy.
Figure 3.7 shows the layout of CN2 connector:
