Thanks to the experience acquired in the field of process control and thanks to a perfect expertness of themost recent technologies, the engineers of Fuji Electric have designed one of the most complete controllers
series available on the market. The equipment of a special machine, the control and drive of an industrial
oven, and the control of a 3-element boiler are a few examples of all the applications that can be realized
with a Fuji Electric controller.
FUZZY LOGIC
Conventional PID Fuzzy logic algorithm, used by the Micro-Controller “X “ and the controller “PYX”,improves in a important way the response of the controller during start-up and in-pro-
cess, thanks to a better prevention of set point overshoot and to suppression of transient
overshoots due to external disturbances.
Simple to use and cost saving, the Micro-Controller “X” is available in 5 sizes : 24x48 , 48x48 , 72x72, 48x96 and 96x96 mm. Theinput signal may be of
Thermocouple, resistance
industrial bulb, voltage or current type. The command signal may be of relay, transistor or4-20 mA type. 3 control modes are available : On/Off, PID auto-tuning with fuzzy logic, and heating/cooling (2 control outputs).The “PYX” Controller is available in 3 sizes : 48x48, 48x96 and 96x96 mm, with universal input signal (Thermocouple, resistance bulb,voltage or current). The command signal may be of relay, transistor or 4-20 mA type. 3 control modes are available : On/Off, PIDauto-tuning with fuzzy logic, and heating/cooling (2 control outputs). Auto / Manual command of control loop is available on thefront panel. The “ PYX “ can optionally have one logic input (set-point selection), one external set-point input, one re-transmissionoutput for measured value / set-point / output, one 8-segment set-point generator and a RS485 MODBUS
“X” Micro-Controllers
TM interface.
The features of the new process controller “CC-M”, real process micro-computer, allow this device to be used in all industry sectors as a simple PID or
as the “heart” of a much more complex application.
His graphic colour screen, associated to a library of various displays offers to the
user a real window on his process. The “CC-M” has an important number of
Inputs/Outputs : analog (7 inputs, 9 outputs) and digital (10 inputs, 11 outputs).It is available with 1 to 8
Pid control loops and configuration is made with function blocks. Parameters setting of the device can be made on front panel or via a configuration PC software compatible with IEC 1131-3 standard. A RS485
MODBUS
TM interface allows to integrate the “CC-M” as a basic element of a process control system or supervision system
Recognized as world specialist in the field of power electronic components, Fuji Electric integrated into itsinverters for driving motors at variable speed the best of its technology. This results in compact, powerful,
simple and very cost saving devices.
To meet all the applications needs, 3 ranges are available (FVR-C11S, FVR-E11Sand FRN-G11S) corresponding to powers from 0,1 to 280 kW. Inverters FVR-
E11S and FRN-G11S integrate the torque-vector control to obtain, whatever
the motor’s demand may be, the optimal current and voltage output and to
grant an efficient torque. The excellent performances of the power transistors (Fuji Electric IGBT) used inour inverters allow an operation of the motor as silent as if this one was directly connected to the power line.These devices are in conformance with the low voltage directives 73 / 23 / EECand EMC 89 / 336 / EEC.
