Specifications

2 Introduction and Component Names

The Encoder (PG) Feedback Card (hereafter referred to the PG-X2 card) is mounted on the

drive’s control board to provide speed and direction feedback. The drive’s control logic can use

this information for purposes such as correcting for speed fluctuation caused by motor slip and

maintaining the velocity.

Using standard software, the PG-X2 card can be used for closed loop control (Flux Vector or

V/F with PG). Standard software does not utilize the marker (C or Z) pulse from the encoder.

The PG-X2 card is compatible with the G5, F7 and G7 Yaskawa drives.

The external appearance and component names are shown in Fig. 1
