Change log:

[2023:10]

PRODUCT INVOLVED: GD, GDI and NL120Q/X series.

STARTING FROM S/N: DA00014400

ACTION: Encoder SIN/COS Electronics changed.New signal conditioning, filtering and digital calibration.

Protection against wrong voltage application, voltage invertion and output protections.

Better signal quality, Offset cancellation and Peak to Peak variation reduction

Digital Filtering

WARNING:

1) New phase angle must be calculated from the servo drive !
2) Possible deviation of the tuning parameters on the servo drive
3) Possible needs to retuning the offset and gain if a calibration on the servo drive is present.
