Introduction and Component Names
The Encoder (PG) Feedback Card (hereafter referred to the PG-B2 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-B2 card can be used for closed loop control (Flux Vector or
V/F with PG). The marker (C or Z) pulse cannot be used from the encoder.
The PG-B2 card is compatible with the G5, F7 and G7 Yaskawa drives.
