Installation

This board is to be mounted on the position where standard terminal block board is mounted

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

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.

Switch off the inverter input power source (via the breaker on the power distribution panel),

and check that the inverter operation panel is unlit.

Remove the inverter cover.

Disconnect the flat cable, that is connected to the control board, from the connector

CN2A on the standard terminal block board

Remove the lock screw

(2)

and take off the standard terminal block board

Fit the new VF5X-4575 board as shown in the enlarged view Figure 1-1.

Tighten the screw (2) again and fix the board.

Insert the flat cable into the connector CN2A on the new board.

Switch on the input power source (inverter power) and check that the display

"O./J"

"lla

FF"

shown. If the flat cable

connected wrong, "OFF" display will appear.

that case switch off the inverter input power and connect the flat cable again after the

display on the inverter panel disappeared.

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

set from a pulse signal input.

•Application examples

(1)

The inverter output frequency can be controlled to

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

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

±0.1%

or less

E6580750

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

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

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

•For

Two-Phase Pulse Input Signal Operation

(

For connecting pulse input signals, connect phase A between the terminals PGA1 and

PGA2 and phase B between the terminals

PGB1

and PGB2.

(2) The polarity of the pulse input signal should be:

(3) A discrimination circuit determines forward or reverse operation as well as the operating

frequency command by the pulse of the two phases (phases A and

from the pulse

generator.

(4)

Discrimination of forward and reverse direction is determined by the train of pulses as

shown
