D The factory settings in parentheses are for when the Unit is initialized for 3-wire control.
D The following table shows the settings and section references for some common functions.
Function Setting Section
3-wire sequence (forward/reverse run command) 0 6.1.8
Multi-step speed references 1 to 3 and jog fre-
quency reference 3 to 6 6.1.8
Accel/Decel time 1 and 2 7 1A 6.1.8
Emergency stop 15 6.1.8
FJOG/RJOG commands 12 13 6.1.8
Terminal 13/14 switch 1F 6.1.8
Timer function input 18 7.3.1
Local/Remote Selection (Setting: 1)
OFF Operate with the frequency reference and run command specified in b1-01 (the frequency refer-
ence source) and b1-02 (run source).
ON Operate with the frequency reference and run command set at the Digital Operator.
D With this setting, the multi-function input selects the input method for the frequency reference and run
command.
D The input method can be switched only when the Inverter is stopped.
D The Digital Operator LOCAL/REMOTE Key is disabled when this function has been set in a multi-
function input.
Option Card/Inverter Selection (Setting: 2)
OFF The Inverter frequency reference is enabled.
ON The Option Card frequency reference is enabled.
D With this setting, the multi-function input enables the frequency reference input from the Inverter itself
or the one from Option Card. The frequency reference input can be switched only when the Inverter
is stopped.
D Be sure that b1-01 (the frequency reference source selector) has been set to 0 (Operator) or 1 (external
terminal). Only the frequency reference from the Option Card will be enabled if b1-01 is set to 3 (Op-
tion PCB).
D Setting 2 can’t be selected if the AI-14B is being used and constant F2-01 (AI-14 Input Selector) is
set to 0.
External Baseblock NO (Setting: 8)
OFF Normal operation
ON Baseblock
External Baseblock NC (Setting: 9)
OFF Baseblock
ON Normal operation
D With either of these settings, the multi-function input controls baseblock operation.
D Baseblock is an interruption of the Inverter output. The motor coasts while the baseblock command
is being input.
