In V/f control with PG the ASR adjusts the output frequency in order to eliminate the deviation between the
speed reference and the measured speed (PG feedback). Fig 6.42 shows the ASR structure for V/f control with
PG.

Related Parameters
Multi-function Digital Inputs (H1-01 to H1-05)
V/f Control with/without PG Selection: “D”
• When one of the digital inputs is set to “D” this input can be used to switch over to normal V/f control and
thereby to disable the ASR.
• The ASR is disabled when the multifunction input is ON.
Speed Control Integral Disable: “E”
• When one of the digital inputs is set to “E” this input can be used to switch the speed control between PI
and P control.
• P control is active when the input is ON (Integral value is reset).
ASR Gain switching: “77”
• When one of the digital inputs is set to “77” this input can be used to switch between the ASR P gains set
in C5-01 and C5-03.
• If the input is enabled C5-03 will be used. If the input is disabled C5-01 will be used.
