manual of the inverter.
(1) Confirm that the power is off before performing any work.
(2) Install the IO66-Z board in the location designated by the dotted lines shown in Figure 3.2. (The figure
shows the VF66B-2R222 model, however, the installation location is the same for other models.) If anotheroptional circuit board is already installed, remove it by following the procedure described below. If anotheroptional circuit board is not already installed, skip to (6).
(3) In order to safely remove the optional circuit board, firstremove the SET66-Z board. Remove the 4 screws
indicated by the circles in the figure on the right. Pull the
SET66-Z board away from the VFC66-Z board in order todetach it.
(4) Next, release the two connectors between the VFC66-Z

CAUTION [Installation/Removal]


Avoid excess connection and disconnection of the connectors.
The connector mounting area may become loose, leading to problems such as poor connections.
Do not attempt to insert any object other than a compatible connector.
The connector mounting area may deform, leading to problems such as poor connections.

３．４ LED operation
 LED1 operation
LED1 illuminates in a cycle of about 2 seconds when IO66-Z is operating normally. If LED1 is not illuminatedproperly when power is on, the following situations may be the cause:

The connection between VFC66-Z and IO66-Z may be faulty.



VFC66-Z or IO66-Z may be malfunctioning.

input signal connection methods. The maximum allowable voltage is 24V and the maximum allowablecurrent for any one terminal is 3mA. For more information about the functions of the individual
multifunction input terminals, please refer to the instruction manual of the inverter.
The multifunction input signal can be set to either source mode or sink mode and an internal power sourceor external power source can be chosen for the inverter. In the initial configuration, it is set to source mode.
To switch between source mode and sink mode, place a jumper shunt on either the IO66-Z jumper connector

The IO66-Z can use the VF66B inverter multifunction output. The above figures show typical multifunction
output signal connection methods. Multifunction output is open corrector output of transistor. In order to use it,
DC power supply are required for the exterior. The maximum allowable voltage is 24V and the maximum

allowable current for any one terminal is 20mA. For more information about the functions of the individual

When connecting a PLC input unit outside, IO66-Z can choose a connection in sink mode and source mode.
Recommends using a twist line to a product line of PLC and IO66-Z. When connecting a relay externally, a coiluses a relay of a direct-current operation (for example, OMRON: G7T-112S-DC 24V etc.). Since IO66-Z builds
in the reflux diode which controls surge voltage, it certainly connects the + side terminal of external powersource to P terminal of a terminal block in IO66-Z.
The IO66-Z multifunction output signal can also be used as the VF66B inverter built-in PLC function output
relay. For more information, please refer to the instruction manual of the inverter and the VF66 PCTool
manual.

CAUTION [Wiring]

Before wiring, make sure the power is OFF.
Failure to do so may cause an electric shock or a fire.
G terminal, G-IN terminal, and G-OT terminal in terminal block 1 are not connected to a grounding by
any means.
Doing so may cause equipment failure or damage.

information about configuration parameter A-00, please refer to the instruction manual of the inverter.

- Set b-10 to “4”.
- Set G-03 (described in section 5.1) to a set value that matches the input signal characteristics.
・In the case of voltage input of 0 to ±10V
The rotational direction can be reversed by setting the command input voltage to a negative value. The
rotation speed command value is set as the analog input (2) rotation speed upper limit (G-04) when the input
is +10V. When the input is -10V, it is set as the negative value of the analog input (2) rotation speed upper
limit (G-04). However, it is possible to set a lower limit by setting the analog input (2) rotation speed lower
limit (G-05). (Figure 5.2, left)If the minimum rotation speed (A-01) is other than “0”, the rotation speedcommand absolute value is controlled to prevent falling below the minimum speed. In this case, when thecommand input voltage is around the 0V range, its behavior shows hysteresis characteristics (It will run
forward if started in the forward direction and will run in the minimum reverse speed if started in the reverse
direction) as shown in the right side of Figure 5.2.

・In the case of voltage input of 0 to 10V
The rotation speed command value is set as the analog input (2) rotation speed lower limit (G-05) when the
input is 0V. When the input is 10V, it is set as the analog input (2) rotation speed upper limit (G-04). However,this will be set to “0” if the analog input (2) rotation speed lower limit (G-05) has a negative value. (Figure 5.3)
If the minimum rotation speed (A-01) is other than “0”, the rotation speed command absolute value iscontrolled to prevent falling below the minimum speed. As a speed command, this only allows forward
operation. For reverse operation, a reverse operation command should be used.

・In the case of current input of 4 to 20mA
The rotation speed command value is set as the analog input (2) rotation speed lower limit (G-05) when the
input is 4mA. When the input is 20mA, it is set as the analog input (2) rotation speed upper limit (G-04).
However, this will be set to “0” if the analog input (2) rotation speed lower limit (G-05) has a negative value.
(Figure 5.4) If the minimum rotation speed (A-01) is other than “0”, the rotation speed command absolutevalue is controlled to prevent falling below the minimum speed. As a speed command, this only allows

Chapter ６ PG input/output function
PG input/output functionality is used when driving a motor from the signal which detected the magnetic polelocation and velocity of the rotor by the sensor (PG). PG is a correspondence only a complementary output
with 12V power source. The instruction manual of the inverter is referred to for a selection in PG mode, andan inverter mode change.

６．１ PG input signal
In order to use PG input/output functionality, it is necessary to set correctly the inverter setups parametershown in the following table according to the operation mode of an inverter, and PG specification to be used.
Please also refer to the instruction manual of the inverter collectively.
