Example: Set n003=1, n004=2, n008=0.
Open:
Run according to the frequency reference from multi-function
input terminal FR and RUN command from multi-function
input terminals S1 to S7.
Closed: Run according to the potentiometer frequency reference and
RUN command from the Digital Operator.
UP/DOWN Commands (Setting: n056 = 34)
When the FWD (REV) RUN command is ON, acceleration/deceleration
is enabled by inputting the UP or DOWN signal from multi-function
input terminals S6 and S7 without changing the frequency reference.
Operation can thus be performed at the desired speed. When UP/
DOWN commands are specified in n056, any function set in n055 is
disabled, terminal S6 is the input terminal for the UP command, and ter-
minal S7 is the input terminal for the DOWN command.
