Instruction manual

6. Programming Features

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.
