NOTES FOR SAFE OPERATION
Before installation, operation, maintenance or inspection of this option, a technically quali-
fied individual who is familiar with this type of equipment and the hazards involved should
read this entire manual thoroughly. In this manual, the NOTES FOR SAFE OPERATION
are classified as “CAUTION”.
CAUTION
NOTE
NOTE
Indicates a potentially hazardous situation that, if not avoided, may result in minor
or moderate injury to personnel and damage equipment.
Failure to heed notices labeled with may result in dangerous situations or
equipment damage.
Steps to be taken to insure proper operation and to avoid malfunctions.
CAUTION
CAUTION
• The option card uses a CMOS IC chip. It may break if touched by bare fingers because of static
electricity. Be careful when handling.
• When removing the option card from the drive for transportation or storage, the card should be
placed in the anti-static package it was received in.
• DO NOT alter wiring or connect or disconnect connectors while equipment power is ON.
Failure to observe these cautions may re sult in injury or equipment damage!
Before use,
1. Before installing the Encoder (PG) Feedback Card (the PG-B2 card), read this manual and the man-
ual for the installation of the drive.
2. Before connecting the PG-B2 card or external terminals, turn OFF the main power to the drive and
verify that the CHARGE indicator lamp of the Drive is OFF.
3. When ordering the PG-B2 card, specify the product type and code number.

1 Inspection after Delivery
• Verify that the products received are the products ordered.
Installation of incorrect product may lead to injury or damage.
Prior to shipment, all Yaskawa products undergo rigorous inspection procedures to ensure accu-
racy and reliability. We recommend checking the following items upon receipt.
• Check that the code number (73600-A013X) and product type (PG-B2) labeled on the
actual card correspond to product ordered.
• Check for damage or shortage caused during transportation.
Report any material or manufacturing defects on the card to your Yaskawa representative.

2 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.
