About This Product
The PG-X3 Option allows the user to connect an incremental line driver encoder (PG) for
motor speed feedback to the drive and take advantage of the V/f with PG, Closed Loop
Vector, and Closed Loop Vector for PM motors control modes. The option helps increase the
control accuracy and performance.
This PG signal allows the drive to compensate for subtle variations in the load, while
providing the drive with the necessary data to control the output frequency and maintain an
accurate constant speed.
The PG-X3 Option reads a maximum input frequency from the PG of 300 kHz. Be sure to
select a PG with an output of maximum 300 kHz when operating at maximum speed.
Note: This option cannot be used with an open collector encoder. Use option PG-B3 with open
collector encoders.
