1. Introduction
Thank you for purchasing the PG Feedback Board (PGFB board) for Industrial Inverter,
TOSVERT VF-AS1/PS1 series.
By the use of this optional board, it is possible for the VF-AS1/PS1 series inverters to con-
duct pulse row speed command and vector control with sensor. This instruction manual
describes installation and application of “PGFB board”. Read this manual carefully before
using the board.
Keep this manual near at hand of the operator who uses the “PGFB Board” for future ref-
erence in the maintenance and inspection.
* Please use this option for VF-AS1 that the software version (CPU version 1) is V124 or succes-
sor.
When it is used with the V106 or earlier software and the number of pulse inputs except
1024, the motor rotation may become unstable.
Refer to the instruction manual of the inverter for the check method of the version.

3. Connection to the Inverter
Install the PGFB to the inverter according to the procedures below.
3.1.Installation to the Inverter
(1) Confirm that the all power of the inverter are turned off beforehand.
(2) Fastening the board on the inverter
(A) For VFAS1/VFPS1 200V 45kW or less, 400V 75kW or less
1. Inset the minus screw driver into the upper left hole of the front cover. And pull down and
unlock the hook.
2. Pull down and unlock the right hook of the front cover like the left hook.
3. Pull the front cover upper side, and remove the front cover.
4. Using encoder wiring terminal as the front side, push the PGFB board along with the
guide of the board. Make sure the optional circuit board connects firmly with the inverter
and the plastic bosses on the inverter case have securely fitted in the holes for fixation at
the upper and lower parts of the option board.
5. Insert the tabs at the lower part of the front cover into the slots at the lower part of the
inverter to attach the front cover to the inverter.
Note: Wait 15 minutes or more after turning the power off and confirm that the
charge lamp on the inverter is unlit.

Wiring
When conducting wiring, follow the instructions bellow.
- Use twisted pair shield wire for signal lines.
- Applicable wire size is 0.2 to 0.75 mm².
- Peel the wire end for about 5 mm.
- When wiring, use a screw driver with the blade thickness of about 0.4 mm and width of
about 2.5 mm.
- Tightening torque for terminal base should be about 0.22 to 0.25 N・m.
- Never bind the signal lines and main circuit wiring.

4. Functional Description
In this section, functions added by the installation of the PGFB board, on top of the stan-
dard inverter functions, are described.
4.1.Vector control with sensor
Using the pulse-row feedback signal from the encoder installed on the motor shaft or load
rotation shaft, vector control with sensor can be conducted.
Speed control operation :0 speed to 150% torque, speed control range 1:1000 (1000 ppr-PG)
speed accuracy ±0.02% (50Hz base digital input)
Torque control operation :Torque control accuracy: ±10% (torque control range: –100% to 100%)
4.1.1.PG feedback wiring
In case of VEC004,VEC005Z,VEC006Z (complementary/open collector)
As for the pulse input signals, A and NA are connected for Phase A, B and NB are con-
nected for Phase B.
The polarity of the pulse input signals should be as follows:
+ side: A, B
- side: NA, NB
The encoder installation direction and signal line wiring should be determined so
that the signal that are fed back from the encoder will show the waveform shown in
Figure 4-1 in terms of the motor rotation direction.
* Forward rotation or reverse rotation is judged from the feedback pulses of Phase A
and Phase B (2-phase pulse that have 90 degrees of phase difference). Therefore, it
should be noted that, when connections are wrong, there is possibility for abnor-
mal rotation of the motor.

1. For PG feedback signal, connect terminals A and NA.
2. The judgement on forward rotation and reverse rotation is impossible.
Only the speed control mode is applicable.
