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.
: These are steps to be taken to insure proper operation
and to avoid malfunctions, etc.
CAUTION
SThe option card uses a C MOS IC chip. It may break if touched by bare
fingers because of static electricity. Be careful when handling.
SWhen removing the option card from the inverter for transportation or stor-
age, put the card into the anti-static package it was in when delivered.
SNever 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-X2 is mounted on the control board of the inverter,
and performs speed feedback using the pulse generator (PG) on the motor to cor-
rect 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:

Before use,
(1) Before using PG−X2, read this manual and the manual for the
installation of the inverter.
(2) Before connecting PG−X2 or external terminals, turn OFF main power
of the inverter and verify the CHARGE indicaor lamp of the inverter is
OFF.
(3) When ordering PG−X2, specify the name and code number.
1Inspection after Delivery
CAUTION
SVerify 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.
SCheck the name written on the product to verify that ordered products have
been delivered.
SCheck for damage caused during transportation.
If there is anything uncertain on the structure, contact your YASKAWA repre-
sentative.

2Installing to Inverter (See Fig. 3)
2.1 Installation Procedure
1Turn 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.
2Insert 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. In-
sert 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.
3Align the two holes of PG−X2 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−X2
spacer mounting hole. (See part A of the side view.)
Verify that 4CN is precisely aligned to PG−X2. Gently push the card until
it clicks.

Notes on wiring
SSeparate the control signal wires ( from terminals TA1 and TA2 ) of the
PG−X2 from the main circuit wires and other power cables.
SUse 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 100m or shorter.

*For two−phase pulse input from PG, input 90°lead pulse to A−pulse side and 90°delay pulse to
B−pulse side during forward run.
PG signal output
The PG signal output (phases A and B) may vary according to installation loca-
tion 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.

9
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.
STo prevent noise, use shielded wire and separate from heavy current circuits
(200VAC or greater) or relay drive circuits. (Wire length to the PG connec-
tor must be 50m or shorter.)
SConnect both ends of the unused wire of the shielded wire to the 0V termi-
nal.
SConnect the grounding lead wire (E) to pin 12 of the control board of the
inverter.
SApplicable wire sizes for terminal block TA1 and TA2 are shown below.

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.

5Selecting PG
The maximum frequency of PG output pulse that can be detected is 300kHz.
Find output frequency, fPG (Hz), according to the following formula.
fPG (Hz) =Motor rotation speed (r∕min) at max. frequency output
60 ×PG constant (p∕rev)
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.)
