Functions
V/f Control with Speed Feedback
This function performs V/f control along with slip compensation by loading as feedbacks (FB)
the pulse trains from the encoder that have been input to the RP and EB terminals.
When this function is used, set Control Method (A044/A244) to "00: Constant torque
characteristics," "01: Reduced torque characteristics" or "02: Free V/f setting."
Refer to "Encoder Connection" on page 5-157 for details on encoder wiring and feedback pulse
selection.
