When connecting a PLC input unit outside, OPCN66-Z can choose a connection in sink mode and source
mode. Recommends using a twist line to a product line of PLC and OPCN66-Z. When connecting a relay
externally, a coil uses a relay of a D.C. operation (for example, OMRON: G7T-112S-DC24V etc.). Since
OPCN66-Z builds in the reflux diode which controls surge voltage, it certainly connects the + side terminal of
external power source to P terminal of a terminal block in OPCN66-Z.
The OPCN66-Z multifunction output signal can also be used as the VF66B inverter built-in PLC function
output relay. For more information, refer to a "OPCN66-Z communications protocol description" and the
instruction manual of the inverter, and the description of VF66 PCTool.



CAUTION [Wiring]

Before wiring, make sure the power is OFF.

Failure to do so may cause an electric shock or a fire.

COM terminal and G terminal in terminal block 1 are not connected to a grounding by any means.

Doing so may cause equipment failure or damage.

(*) This is set as a percentage with respect to the maximum rotation speed (configuration parameter A-00).
For more 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 speed command
absolute value is controlled to prevent falling below the minimum speed. In this case, when the command input
voltage is around the 0V range, its behavior shows hysteresis characteristics (It will run forward if started in theforward direction and will run in the minimum reverse speed if started in the reverse direction) as shown in theright 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 is controlled
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 absolute value
is controlled 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.

Figure 7.2 Connection with a termination station
The above figure shows the connection method with other stations. The example which uses the transmission
cable of the twisted pair shield of 2P by a diagram is expressed (a transmission cable recommends
CO-SPEV-SB(A)2Px0.5 of Hitachi Cable).
Please connect a terminator to a termination station.
When the terminator is not connected to the master station, please connect a terminator like a termination
station.
※A shield line is connected to 0V (SG) terminal of the signal wire of a master station.
※When OPCN66-Z is an end station, a 100 ohms (more than 1W) terminator is connected among
terminals A and B. Please cover the lead of a terminator by a clothing tube and the end of a leadshould attach a pressure terminal (please solder a pressure terminal and a lead for the prevention
from disconnection).

７．２ Setup of OPCN-1 communication function
Through OPCN-1 communication, the OPCN66-Z can input operation and speed commands, torquecommands and multifunction input to the VF66B Inverter as well as monitor factors such as operating
conditions, protection conditions, current and voltage. It can also read and alter the inverter configuration data
as well as read the trace-back data, protection history and monitor data.
For information about OPCN-1 communication, please refer to the “OPCN66-Z Communication Protocol
Manual”. Furthermore, it can be used as the input/output signal of the VF66B Inverter built-in PLC function. For
information about the built-in PLC function, please refer to the VF66 PCTool manual.
