MANUAL NO. TOE-C736-40.2B
NOTES FOR SAFE OPERATION
Read this instruction manual thoroughly before installation,
operation, maintenance or inspection. In this manual, the NOTES
FOR SAFE OPERATION is classified as “CAUTION”.
CAUTION
Indicates a potentially hazardous situation which, if not avoided, may
result in minor or moderate injury to personnel and damage to
equipment.
It may also be used to alert against unsafe practices.
Even items described in
CAUTION
may result in a vital accident in
some situations. In either case, follow these important items.
NOTE
: These are steps to be taken to insure proper operation
and to avoid malfunctions, etc.
CAUTION
S The option card uses C MOS IC chips. It may break if touched by bare
fingers because of static electricity. Be careful when handling.
S SWhen removing the option card from the inverter for transportation or
storage, put the card into the anti-static package it was in when delivered.
S Never change wiring or connect or disconnect connectors while the power
is ON.
Failure to observe this caution may injure you.

PG speed controller card, PG-B2 is mounted on the control board of the inverter,
and performs speed feedback using the pulse generator (PG) on the motor to correct speed fluctuations caused by slipping. Motor rotation direction is detected
by phase A and phase B PG pulse inputs. The card is used for flux vector control.
This option card is applicable to the following inverter series:

NOTE
1
Before use,
(1) Before using the PG−B2, read this manual and the manual for the
installation of the inverter.
(2) Before connecting the PG−B2 or external terminals, turn OFF main pow
er of the inverter and verify the CHARGE indicaor lamp of the inverter
is OFF.
(3) When ordering the PG−B2, specify the name and code number.
Inspection after Delivery
CAUTION
S Verify that ordered products have been delivered.
Installation of a wrong device may lead to injury or damage.
Though the products have undergone rigorous inspection before shipping, check
the following for safety.
S Check the name written on the product to verify that ordered products have
been delivered.
S Check for damage caused during transportation.
If there is anything uncertain on the structure, contact your YASKAWA representative.

Installation Procedure
1
Turn OFF the main power and wait for the time specified on the cover of the
inverter. Remove the cover and verify that the CHARGE indicator lamp is
OFF.
2
Insert the attached spacer (SRNT41028−9) into the spacer mounting hole
in the mounting base of the inverter. (See Fig. 3.)
Inverters of 3.7kW or smaller capacities have two closely placed holes. Insert the spacer into the hole on the 7CN side. Inserting into the wrong hole
will stack the spacer. Be careful to insert in the proper hole in the proper
inserting direction.
Align the two holes of PG−B2 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
3
spacer mounting hole. (See part A of the side view.)
Verify that 4CN is precisely aligned to PG−B2. Gently push the card until
it clicks.

Notes on wiring
S Separate the control signal wires ( from terminals TA1 and TA2 ) of the
PG−B2 from the main circuit wires and other power cables.
S Use a shielded wire to connect to the PG. Connect the wire as shown in Fig.
5 to prevent interference by noise. The wire must be 300m or shorter.

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, connect 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_.
Make sure the followings when wiring.
S PG cable must be 300m or shorter. If it is 100m or shorter, provide an exclusive cable. ( Refer to the table below.)
For wire length of 100m or shorter, use type of KPEV−S, 0.5mm2.
For wire length from 100 to 300m, use type of KPEV−S, 1.25mm2 and a
junction terminal.

Notes on selecting cables
Too thick a cable applies pressure to the option card and may lead to failure.
Too thin a cable may lead to imperfect contact or a break in the wire.

Selecting PG
The maximum frequency of PG output pulse that can be detected is 32,767Hz.
Therefore, select a PG that outputs about 20kHz at the motor rotation speed at
maximum frequency output.

Notes: S The motor rotation speeds at maximum frequency output are represented as synchronous

S If the PG power capacity is 200mA or greater, provide a separate power supply.
(If momentary power loss ride-through function is necessary, provide backup capacitor or
take other necessary measures.)
