34 Up or down command Up or down command (set in n056 only)
By setting n056 to 0, the set value in n055 is ignored and the
following settings are forcibly made.
S6: Up command S7: Down command
Note It is impossible to set the up or down command and multi-step
speed references 1 through 4 together.
Note To keep the frequency reference that has been adjusted with
the Up or Down command after the Inverter is turned OFF, set
n100 (Up/Down frequency memory) to 1.

The communications function is tested by connecting the
transmission and reception terminals together and checking that
the data received is the same as the transmission data.
Note Set value 26 is available for 5.5- and 7.5-kW Inverters only.
H Operation in 2-wire Sequence (Set Value: 1, 2)
• The Inverter operates in 2-wire sequence by setting a multi-function input selection to 1 (forward/re-
verse) or 2 (reverse/stop).
