CAUTION
NOTE
• 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.

1 Inspection after Delivery
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.
• Verify that the products received are the products ordered.
Installation of incorrect product may lead to injury or damage.

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.
The external appearance and component names are shown in Fig. 1

3 Installation Procedure
3.1 Before Installation
Remove contents from package and verify that a mounting spacer (code number
SRNT41028-9) is included with the PG-B2 card (see Fig. 2).
Fig. 2 Spacer
3.2 Drive Installation Procedure
1. Turn OFF the main power and wait for the time specified on the cover of the Drive for
voltage to bleed off the DC bus capacitors. Remove the cover and verify that the
CHARGE indicator lamp is OFF.
2. Insert the spacer (SRNT41028-9) into the spacer mounting hole in the mounting base of
the Drive (see Fig. 3). Drive models of 3.7 kW or smaller capacities have two closely
spaced mounting holes. Insert the spacer into the hole closest to the 7CN connector on
the control board. Insertion of the spacer into the incorrect hole will stack the spacer. Be
careful to insert in the proper hole in the proper inserting direction.
3. Align the two holes of the PG-B2 card and projections as shown in the detailed side
view, first at location (a) and then at (b), and precisely place the card on the option A
connector. Insert the spacer mounted at 2 above into the PG-B2 spacer mounting hole.
(See part A of the side view on the next page.)
4. Rotate the top edge of the card down into place, carefully aligning connector 4CN on
the back of the card with connector 4CN on the control board.
5. Gently press the card into place until 4CN and the spacer click into place.
6. Connect the grounding lead wire of the PG-B2 card to the grounding terminal (G5: 12
(G), G7 or F7: E (G)) on the control board.

Note: Be sure to remove the option clip before installing the PG-B2 card. If
the card is installed with the clip attached, the card cannot be cor-
rectly installed, and the card will perform poorly.

4 Interconnection
Fig. 4 shows interconnection between the Drive, the PG-B2 card, and peripheral equipment.
Note: The PG terminal symbols are the examples when using a Yaskawa’s motor.
PG type: LMA-B-S185Y (complementary output)
The pulse monitor emitter is connected to common inside the PG-B2.
The emitter common must be used for external circuits.

5 Wiring
5.1 Terminal Functions
* Up to +14 V ±5 % can be supplied by adjusting variable resistor RV1.
RV1 is set to 13.0 V at the factory prior to shipment.
PG Signal Output
The PG signal output (phases A and B) may vary according to installation location on the
motor. Refer to Fig. 4 for correct wiring.
In general, motor forward direction is counterclockwise (CCW) as viewed from the load
shaft. For YASKAWA’s motor, phase A of PG output leads phase B by a phase angle of 90°
in clockwise (CW) rotation. According to PG, phase A lags phase B by a phase angle of 90°
in clockwise (CW) rotation. In this case, when PG is installed at the opposite drive end, con-
nect phases A and B output from PG to the option card as it is.
For YASKAWA’s Inverter motor with PG, PG is installed at the opposite drive end. Then,
phase A lags phase B by a phase angle of 90°at motor forward run. (Motor runs CCW as
viewed from PG.) Therefore, when using this motor or similar motors, connect phases A
and B to the option card after replacing phase output. The pulse monitor on this option
shows phase A leading phase B by a phase angle of 90°.
