This manual introduces the use of the winding control function of the Mitsubishi FR-A740-0.4K~500K-CA1 variable frequency drive.
This manual describes the special specifications added to the standard FREQROL-A700 frequency converter for winding and unwinding machinery. It explains the floating roller control, diameter compensation, and various input/output signal functions, and includes application examples for printing and line winding machines.
The document contains tables of special specifications, system configuration examples, control block diagrams, and detailed parameter settings such as PID gain switching, speed compensation, and monitor functions. It also lists the required external terminal signals for configuring the device. This manual is written in Chinese.
It is intended for winding and unwinding machinery, especially paper winding in printing machines and line winding machines.
PID gain can be switched using an external terminal input signal.
The device provides input signals for floating roller position detection, line speed input, and other control functions.
