6.12 DIO Expansion Card OPC-VG1-DIO
6.12.1 Product overview
The use of optional OPC-VG1-DIO expansion cards makes it possible to add I/O
points, i.e., up to 16 DI points and 10 DO points can be added per optional
expansion card. The use of the OPC-VG1-UPAC as another option (available
soon) will enable user programs to operate these optional I/O points.
(1) Main applications
Use SW2 on the optional expansion card to select DIOA or DIOB.
If DIOA is selected:
If DIOA is selected, four DI points and eight DO points will be available. In that
case, the control functions of the FRENIC-VG will be available as well. These
control functions include input control functions, such as coast-to-stop command,
multistep speed change, servo lock functions, and output control functions, such
as speed agreement and running functions.
If DIOB is selected:
If DIOB is selected, 16 DI points and 10 DO points will be available. These I/O points are operable
through an UPAC option. That is, these I/O will be operable on user programs written with an UPAC
option.
The I/O control of DIOB cards mounted to other inverters will be possible if a terminal block supporting
high-speed serial communication is mounted in addition to the UPAC option.
(2) Photocoupler insulation
The I/O interface block is photocoupler insulated.
(3) Sink/Source
The I/O interface block allows the section of current sink output (hereinafter referred to as SINK) and
current source output (hereinafter referred to as SOURCE).
The output interface block allows bi-directional power connections.
Interfaces in general often used in Japan and the United States has SINK output. This output is set to 0 V
with signals activated. Interfaces often used in Europe has SOURCE output. This output is set to +V with
signals activated.
OPC-VG1-DIO expansion cards will not be available if a PLC terminal is used for the circuit in control of
the built-in digital input pins (FWD, REV, and X1-9) of the FRENIC-VG. For details, contact your Fuji
Electric representative.
(4) I/O check functions
The selection of either DIOA or DIOB makes it possible to confirm the ON/OFF status of each I/O signal
through the keypad or over communication (RS-485, T Link, CC-Link, SX bus, and UPAC).
(5) Optional function codes
Function codes to allocate FRENIC-VG I/O control functions will be operable if DIOA is selected.
Specifically, the corresponding function codes (E10 to E13 and E20 to E27) will be displayed on the
keypad by selecting DIOA if the option is mounted. Use these functions to allocate functions to four DI
points and eight DO points.
