•The precautionary items list critical information for safety. Be sure
to heed these items at all times.
•The following conventions are used to indicate and classify pre-
cautions in this instruction sheet.
DANGER! Not following a precaution given as a “DAN-
GER” is likely to result in fatal or serious injury.
WARNING Not following a precaution given as a
“WARNING” may result in fatal or serious injury.
Caution Not following a precaution given as a “Caution”
can result in injury to people or damage to the
product or system.
Items listed under caution may also have serious consequences de-
pending on the circumstances, so be sure to heed these items at all
times.
Mounting
WARNING Never reach inside the Inverter as this may
result in an electrical shock.
WARNING Do not mount, remove, or wire Optional Cards
without first shutting the Inverter power OFF and
waiting until the prescribed amount of time
(indicated on the front cover of the Inverter) has
passed after all indicators on the Inverter are no
longer lit. Failure to do so may result in an
electrical shock.
WARNING Do not nick, apply undue stress, place heavy
objects on, or sandwich cables. Otherwise, this
may result in an electrical shock.
Caution Do not touch the elements of Optional Cards.
Otherwise, this may result in injury due to elec-
trical shock.
Connections and Settings
Caution Do not change settings unless absolutely nec-
essary. Otherwise, this will result in injury or
equipment damage.
Caution Do not mount or remove an Optional Card with
Inverter power ON. Otherwise, this will result in
injury or equipment damage.
Caution Be sure to connect the ground wire (E) of
Optional Cards. Otherwise, this may result in
equipment damage or faulty operation due to
noise.
Description
The 3G3FV-PPGj2 PG Speed Control Card is an Optional Card
used only with the SYSDRIVE 3G3FV Inverter.
This Optional Card controls motor speed and feeds back speed in-
formation to the Inverter from pulse generators (speed detectors,
such as encoders and pulse generators).
The Card is mounted on a 3G3FV Inverter control circuit board.

Mounting Procedure
1, 2, 3... 1. Be sure to turn OFF the main Inverter power supply,
wait at least 1 minute (at least 3 minutes for 30-kW-or-
higher Inverters), remove the front cover of the Inverter,
and make sure the charge indicator is not lit.
2. The PG Speed Control Card is an option A. Mount the
Card in the option-A location as shown in the diagram
below.
3. Insert the spacer that is provided into the spacer mount-
ing hole located on the mounting base of the Inverter.
There are 2 holes located on 3.7-kW-or-lower Inverters.
Insert the spacer in the hole on the 7CN side. Be very
careful because spacers cannot be removed if they are
inserted in the wrong hole.
4. Proceed in order with steps Aand Bin the enlarged
view below. Align the PG Speed Control Card and the
supports, make sure the connector on the Card is
aligned with the option-A connector, and then push the
spacer through the spacer mounting hole on the Card.
(Side View a)
Make sure the 4CN positions are properly aligned, and
push the spacer through the hole until it clicks into
place.
5. Connect the ground wire of the Card to the FG terminal
12(E) on the Inverter control circuit board.

Selecting the Number of PG Pulses
3G3FV-PPGA2/PPGB2
The maximum response frequency is 30 kHz.
Select a smaller number of pulses than those given below if neces-
sary based on the encoder pulse width deviation (90±45°phase dif-
ference) and waveform distortion that occurs with longer cables.
(With an open collector I/O, longer cables increase waveform distor-
tion and make higher frequency pulses difficult to read.)
Maximum motor speed (r/min) 1,800 1,500 900
Encoder pulse count [p/r] 500 600 1,00
Maximum encoder frequency [kHz] 15 15 15
3G3FV-PPGD2/PPGX2
The maximum response frequency is 300 kHz.
The number of encoder pulses (upper limit) can, depending on the
encoder pulse width deviation (90±45°phase difference), be calcu-
lated using the equation given below.
No. of encoder
pulse [p/r] 60 x max. response freq. (300 kHz)
2 x max. motor speed (r/min)
=
We recommend an encoder of 1,000 to 2,000 [p/r] if the maximum
motor speed is less than 4,000 r/min. Selecting an encoder with a
higher resolution than required will not improve the speed control
range or precision.
Parameter Settings
Control Method Selection: A1-02
When selecting the control method (A1-02), use the control method
setting for the particular Optional Card.
Set “1”(V/f With PG Feedback Mode) for the 3G3FV-
PPGA2/PPGD2 and “3”(Flux Vector Control Mode) for the 3G3FV-
PPGB2/PPGX2.
PG Speed Control Card: F1-01 to F1-13
Use the PG Speed Control Card settings for the application.
A more detailed description of the settings is given in Chapter 5 Basic
Operation of the SYSDRIVE 3G3FV User’s Manual (I516).
Check your settings by referring back to5-4 Flux Vector Control and
5-5 V/f Control with PG.
