Service Bulletin - Integrated Encoder

Change log:

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.
