6.10 Synchro Interface OPC/MCA-VG1-SN
6.10.1 Product overview
The OPC-VG1-SN is an OPC series interface option for the FRENIC-VG. The
OPC series consists of printed circuit board-type control options that are
installed into the inverter unit. One analog interface option OPC series product
can be installed in each inverter unit.
The OPC-VG1-SN, which is used to perform position control using a synchro
transmitter, converts synchro transmitter signals to signals in the range of 0 V
to ±10 V.
The MCA-VG1-SN is a standalone option unit with built-in OPC-VG1-SN
functionality. It can also be used in combination with other models (FRENIC
series inverters).
The MCA-VG1-SN is available soon.
• The synchro interface's internal switches and knobs are pre-adjusted at the factory. Never touch knobs,
switches, or other adjustments other than those designed to be adjusted or set by the user.
• Place the MCA (standalone type) vertically with the connection terminals facing down near the inverter and
connect wiring so as to protect signals from noise. The MCA (standalone type) uses a separate power supply
(±15 V). You will need to provide a stabilized power supply (±15 V DC) since power is not supplied from the
FRENIC-VG.
