Safety Precautions Instruction manual
To prevent electric shock, Al WAYS observe the following precautions:
Screws
r7
~
ROM board;.
with cover
1. Do not touch the charging sections on the terminal block, etc. while the CHARGE
lamp is lit. As the electrolytic capacitor inside the unit will retain a charge, touching
these sections may result
in electric shock. Before connecting the wires to the motor
terminals, turn off the input power to the inverter, and do not proceed unless the
CHARGE lamp is unlit.
2. Do not touch or insert a rod, etc. into the inverter while the power is being supplied.
This may result
in electric shock or damage to the equipment.
When the board
is being operated with the cover removed, the charging sections will
be exposed. In such cases, be sure to mount the board inside the panel to prevent
these points from being touched from the outside.
3. Be sure to ground the G/E terminal on the unit. Also ground the motor. (Failure to do
this may result
in electric shock due to current leakage.)
4. NEVER attempt to modify the unit.

2 Installation
The 12-bit binary option board is installed onto the control board in the VF-AS unit. Use
the following procedure for installation.
(1) Check to make sure the input power is off (with the switch on the distribution panel set
to the OFF position).
(2) Remove the inverter cover.
(3) After the CHARGE lamp on the inverter goes out, wait at least five minutes, then
install the board using the following procedure.
(4) Remove the ROM interface window and the control panel. For directions on how to
remove these parts, see the VF-AS Instruction Manual.
· (S) Using the following procedure, install the ROM board with cover CD that came with
the unit (see Figure
2-1 ).
1. Remove ROM cover ~- Pull the tab forward to remove the cover.
2. Check to make sure that ROM board connector @ is attached at the location
from which the ROM cover was removed.
Note: If there is an IC fastened here instead of a connector, the ROM board with cover
is incompatible. Contact one of the Toshiba branches, sales offices or dealers
listed
on the back cover. Also note that it is not necessary to install the
accompanying ROM board with cover
on inverters with CPU versions 120 or later;
do not install the board on these models. The CPU version can be checked with
[u [PU] accessed under [ [, r .u t]. For example, if the CPU version is 120, " 12 D"
will be displayed for [u [PU].
3. Insert the ROM board with cover into the ROM board connector until it clicks into
place.

If [Er r Y] appears on the display during operation, it may be because the ROM board
with cover has not been inserted properly. Turn off the input power and insert the ROM
board properly.
(6) Use the following procedure to install the 12-bit binary option board (see Figure 2-2).

1. There are three large holes on the 12-bit binary option board. Insert the board so
these holes accommodate control panel connector @ and RS-232C
communications connector ® on the control panel, and control panel fastening
stud ®
on the support.
2. Insert connector CNSN on the bottom of the 12-bit binary option board into
connector
CNS (J) on the control board.
(7) Fasten the 12-bit binary option board to the support using the accompanying screws
(one 3 x 6 and two 3 x
8) to the three small holes (@, ® and @)) on the 12-bit binary
option board (see Figure 2-2).

(8) Using the accompanying wires, connect the control terminals P24 and CC on the
inverter control terminal block board to terminals P24 and
CC on the 12-bit binary
option board (see Figure 2-2).
Red wire . @...........P24 -P24
Black wire @...........ec - CC
(9) Fasten the ROM interface window and control panel in place. For directions, see the
VF-AS Instruction Manual.
(1 O)There is a window on the right side of the inverter cover. Break this section to create
the wire window and, after connecting the wires, attach the inverter cover.
Note: If there are burrs on the cut ends, remove these burrs before connecting the wires.
The wires may be damaged if this is not done.

3 Functions
3-1 12-bit Binary Input or 3-digit BCD Input
It is possible to set the inverter operating frequency using the external contact signal from
a programmable controller or a relay sequence. The operating frequency can be set with a
maximum resolution
of 1/4095 (for 12-bit binary input) or 1/999 (for 3-digit BCD input).
Using a read timing terminal enables the operating frequencies for two or more inverters
to be set
in sequence using a single bit setting circuit.

.(2) A write input switch may also be used.
Connection Method
• Use a shielded wire for the signal wire.
• NEVER bind the signal and main circuit lines together.
• Use of a wire of diameter 0.75mm2 is recommended.
3-1-3 Input Method
(1) Use the contact signal to set the inverter operating frequency.
(2) Figure 3-1-1 shows the bits and the number
of digits for 12-bit binary input and 3-digit
BCD input.
(3) The contact is
on when the bit is set to 1 and off when the bit is set to 0.
(4) Figure 3-1-2 shows an example of contact input for 12-bit binary input.
