18 LINK operation
• Frequency setting can be made by means of communication
with RS-485 as standard.
• Optimum control is enabled, by controlling feedback signal in air-
conditioning unit.
• Highly precise speed control can be performed with 16-bit serial
signal by connecting FUJI PLC “MICREX-F” via an option card
(OPC-G11S-TL).
• Using the option cads (OPC-G11S-
MMM
) below enables
several types of communications.
• Profibus-DP, DeviceNet, Modbus Plus, Interbus-S, CAN open
