Introduction
The Dual Encoder (PG) Feedback Card (PG-Z2) (Figure 1) is mounted on the drive’s
control board to provide speed and direction feedback from two encoders. The drive’s
control logic can use this information for purposes such as correcting for speed
fluctuation caused by motor slip, maintaining the velocity and phase relationship
between two machine (motor) shafts, and aligning a spindle at stop for tool changing.
Using standard software, the PG-Z2 can be used for closed loop control (Flux Vector or
V/F with PG) of one or two motors. The second motor is selected by using a multi-
function digital input programmed for “Motor 2 Select”. Standard software does not
utilize the marker (C or Z) pulse from the encoder.
Custom software titles such as Electronic Line Shaft, and others utilize the PG-Z2 card.
The configuration varies so please consult the specific software technical manual. The
marker pulse may be needed depending on the software.
The PG-Z2 option card is compatible with the F7 and G7 Yaskawa drives. The G5 is
not compatible and uses the PG-W2 option card instead.
