1. Installation
This board is to be mounted on the position where standard terminal block board is mounted
in VF-A5 inverter. Replace the standard terminal block board with this VF5X-4575 board
following the procedures below. When the board has already been installed
in the inverter at
your purchase, replacement is not necessary.
A.CAUTION:
Mounting or removing the board while the panel displays is illuminated can result in
electric shock.
Before mounting or removing the board, switch off the inverter input power source (via
the breaker on the power distribution panel) and check that the inverter panel is unlit.
1. Switch off the inverter input power source (via the breaker on the power distribution panel),
and check that the inverter operation panel is unlit.
2. Remove the inverter cover.
3. Disconnect the flat cable, that is connected to the control board, from the connector
CN2A on the standard terminal block board
(1 ).
4. Remove the lock screw (2) and take off the standard terminal block board (1 ).
5. Fit the new VF5X-4575 board as shown in the enlarged view Figure 1-1.
6. Tighten the screw (2) again and fix the board.
7. Insert the flat cable into the connector CN2A on the new board.
8. Switch on the input power source (inverter power) and check that the display "O./J" or
"lla FF" is shown. If the flat cable is connected wrong, "OFF" display will appear. In
that case switch off the inverter input power and connect the flat cable again after the
display on the inverter panel disappeared.

2. Functional Description
This section describes the additional functions of the board VF5X-4575 besides those of the
standard functions of VF-A5.
2.1 Pulse Input (Frequency setting)
The inverter operating frequency command can be set from a pulse signal input.
•Application examples
(1) The inverter output frequency can be controlled to be proportional to the frequency of a
pulse output signal from a pulse generator.
(2) When using a pulse generator, forward and reverse operation is possible by inputting
the pulse of two phases (A and
8) that have 90-degree phase difference.
2.1.1. Pulse Input Specifications
Table 2-1 Pulse input specifications
Item Single-phase Two-phase
Maximum pulse input frequency 120kHz or less 60kHz or less
Pulse input voltage 12Vdc to 18Vdc (for VF5X-4575A)
Speed control

2.1.2. Pulse Input Connection Procedure
• Use twisted shield wire for signal connection.
• Never bind the signal wire and the main circuit wire together.
• Recommendatory wire diameter is 0. 75mm2•
•For Single-Phase Pulse Input Signal Operation
(1) Connect the pulse input signal between the terminals PGA1 and PGA2 or between PGB1
and PGB2.
(2) The polarity of the pulse input signal should be:
+side ... PGA1 or PGB1
-side ...PGA2 or PG82
(3) Changeover of the forward and reverse operation is possible when the command mode is
valid for terminal input (parameter
[fl I] d of G ,- .LI t is I) among the terminals ST,
F, Rand CC.

2.2. PG Speed Feedback Control Using Pulse Input
This application performs speed feedback control in which motor speed fluctuations due load
variations are corrected using a pulse train feedback signal from an encoder mounted on
either the motor shaft or a rotating shaft in the load.
The system can provide a motor speed control precision with respect to the set frequency of
better than
0.1 % (60Hz base).

*1 : Adjust four parameters while running the inverter as described below.
• [, P(Proportional gain) is a coefficient multiplied by the deviation (the difference between
the set frequency value and the feedback). The proportional control action provides a
correction that is proportional to this deviation.
• [, I (Integration time) eliminates the deviation (remaining deviation offset) that
accumulates in the proportional control. By counting the integration time of the offset
adjustment continues until the offset is completely eliminated.
• [, Fl (Differentiation time) determines operation that improves the response time.
However, note that increasing this value increases the system's sensitivity to noise, and
may result
in large fluctuations in the output frequency.
• [, F 5 (Delay filter) diminishes the rapid changes caused by the differentiation. Normally
this does not have to be changed.
[When hunting occurs during test
run with the value of standard factory settings,
lessen the [,Fl (differential time). If it is not effective, increase the C f (integration
time) and lessen the CP{proportional gain).
*2: PG(number of P
[; input pulses) represents the number of pulses per one revolution.
*3: When the PG pulse input signal is a single-phase, do not select ;~(two-phase) for
P [; P f-1 (PG input phase), or else the motor will run fast or reverse.
*4:
Do not set the value '-I (PG pulse input) for the F[ I and F[ ;~ .
