Encoder Feedback Option Card

PG-X2

1. Part Number: PG-X2.

2. Applicability: F7, G7, GPD515/G5, G5HHP.

3. Introduction: The PG-X2 encoder feedback option card (Figure 1) is mounted on the drive’s Control Board and performs

speed feedback using the pulse generator (PG) on the motor to correct speed fluctuation caused by motor slip. Motor rotation

direction is detected by phase A and phase B PG pulse inputs. The terms encoder, PG (pulse generator), and pulse train are

used interchangeably in this guide. The card can be used for flux vector control or V/Hz with PG feedback control.

4. Receiving: All equipment is tested against defect at the factory. Report any damages or shortages evident when the

equipment is received to the commercial carrier who transported the equipment.

5. Cautions:

a. Hazardous voltage can cause severe injury or death. Lock all power sources feeding the drive in the “OFF” position.

b. This option card uses CMOS IC chips. Use proper electrostatic discharge (ESD) protective procedures when

handling the card to prevent I.C. damage or erratic drive operation.

c. If other option cards are to be installed at the Option C (2CN) or Option D (3CN) positions (See Figure 2), their

installation and wiring should be completed before installation of this option.

d. Before installing this option, a technically qualified individual, who is familiar with this type of equipment and the

hazards involved, should read this entire installation guide.
