Note
1. Be sure to use twisted-pair shielded wire for the signal
line.
2. Do not use the PG power supply for equipment other
than the PG (encoder). Otherwise, noise may cause
faulty operation.
3. Make sure that PG wiring is less than 50 m long.
4. Make sure the signal line is placed at least 30 cm away
from the Inverter output line and other power lines.

Wiring Procedure
1, 2, 3... 1. Use a thin-slotted screwdriver to loosen the terminal
screws.
2. Insert the wire from underneath the terminal block.
3. Tighten the terminal screws firmly.

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.)

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.

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 to 5-4 Flux Vector Control and
5-5 V/f Control with PG.
