Advanced Operation
With this setting, the multi-function input can be used to enable or disable the multi-function analog
input.
Turning the input OFF has the same effect as setting H3-05 (the multi-function analog input selector
for terminal 16) to1F.
ASR Selection (Setting: D)
OFF V/f control with PG feedback (speed control with speed feedback)
ON Normal V/f control with PG feedback (Disables speed feedback control.)
With this setting, the multi-function input can be used to switch "V/f control with PG feedback" to "Nor-
mal V/f control."
It is possible to switch between these control modes during operation.
ASR Integral Reset (Setting: E)
OFF Operates with PI-control speed control loop.
ON Operates with P-control speed control loop.
(The speed control's integral values are reset by the integral time constant.)
This function is valid only in "V/f control with PG feedback" mode when parameter F1-07 is set to 0.
(Setting F1-07 to 0 disables ASR integral operation during acceleration/deceleration.)
It is possible to switch between these speed control modes during operation.
UP and DOWN Commands (Settings: 10 and 11)
UP command DOWN command
ON OFF

OFF OFF
With these settings, the multi-function inputs can be used to control the Inverter's output frequency.
When using this function, be sure to set both the UP command (setting 10) and the DOWN command
(setting 11) in 2 multi-function inputs.
(An OPE03 option fault will occur if only one of these commands is set.)
Be sure to set parameter b1-02 (the run command source selector) to 1 (external terminal). The up/
down function won't operate with any other b1-02 setting.
The frequency up/down commands operate according to the normal acceleration/deceleration times
in C1-01 through C1-08.
The upper and lower limits for the output frequency with the up/down commands are determined by
the following settings:
Upper limit ) Maximum frequency (E1–04)
Lower limit ) Maximum frequency (E1–04)
When frequency reference (voltage) terminal 13 or frequency reference (current) terminal 14 is being
used as a frequency reference input, the greatest frequency value becomes the lower limit.
