• UP/DOWN command (setting: n056 = 034)
With the FWD (REV) run command entered, accel/decel is enabled by
inputting the UP or DOWN signals to multi-function input terminals S6
and S7 without changing the frequency reference, so that operation can be
performed at the desired speed. When UP/DOWN commands are
specified by n056, any function set to n055 becomes disabled; terminal S6
becomes an input terminal for the UP command and terminal S7 for the
DOWN command.
