(1) RMFC: Reference Model Following Control
RMFC control consists of the following:
(1) A machine model where the system is approximated to an ideal one-inertia system.
(2) A speed controller that controls the machine system model.
This control system is called “Reference Model Following Control (RMFC) “because the motor speed is
controlled so that it will follow the model speed output from the reference model.
By combining RMFC control with speed control that comes after, it is possible to configure a
two-degree-of-freedom control system where the speed reference response and disturbance response can
be set separately.
(2) Variable current limiter control (CLC, option)
When performing tension control or torque control of load, it is possible to perform current control
according to the external reference (variable current limiter control (CLC)).
When performing CLC, enter ST signal (See Section 3.5.1) from outside and enter CLC reference by
analog input or transmission input. In this case, increase the external speed reference to the speed limit to
saturate the speed control output.
For speed control gain switching and SFC, see Section 5.4.2.1.
