PID Control Feedback Selection (301FHex-14Hex)
• 301FHex-14Hex = 0: Analog input
If “0: Analog input” is selected for PID Control Feedback Selection (301FHex-14Hex), allocate “5:
PID feedback value” to Input T
erminal [AI1] Function Selection (3005Hex-3EHex). The analog input
value is internally controlled as 0% to 100%. For details on analog input, refer to 8-3-1
Analog Input
(Function Selection) on page 8-32.
When analog input is applied to PID feedback, the following gains, biases, filters and offsets are appli-

• 301FHex-14Hex = 3: Pulse train input
If “3: Pulse train input” is set to PID Control Feedback Selection (301FHex-14Hex), the inverter cap-
tures a value converted into a percentage with the maximum frequency as 100% where the pulse
correction factor (3024Hex-07Hex/3024Hex-08Hex) is multiplied with the frequency value [kP/s] of
the captured pulse train input.
