Frequency converter for asynchronous motor
max. 50.4 A | FC2 SIEB & MEYER

FC2 is conceived for parallel operation of several asynchronous spindles with speeds up to 500,000 rpm. The required interfaces for temperature sensors and motor encoders are already integrated. Thus FC2 can operate up to 12 spindles and monitor the corresponding sensors whereas the proper control does not require any motor encoder. The PAM mode (Pulse Amplitude Modulation) allows operating the spindles without additional motor chokes. The above described features of FC2 reduce the system costs. The device is connected to the control via an analog reference speed value, the serial interface (RS232) or via SERVOLINK 4. The wide-range power input and the integrated power supply of FC2 allow its autarkic use in the machine so that the voltage of the spindles is independent of the voltage of the positioning drives.

Multi-Spindle Operation without Sensor
The control without sensor allows parallel operation of several asynchronous motors. Since motor encoders are not required spindle costs and wiring work are reduced. The reliability of the machine increases as broken cables and electromagnetic interferences in encoder lines have no influence anymore.
