3. Example of operation
To operate 3.7 kW four-pole motors in sensorless vector control mode while switching them by sending a
signal to the S1 and S2 terminals
(1) Set the parameters as follows; cmod=0, pt=3, f182=1, f115=28, f116=30, f411=4,
f412=3.7
(The parameters described in 6.4.1, "Switching among V/f characteristics #1, #2, #3 and #4 from input
terminal," of the inverter's instruction manual also need to be set for each motor.)
(2) The settings of f402, f403, f404 and f410 are changed by turning on or off the S1 and S2
terminals, as described in Table 1 below, and motor data is according to the type of motor used.
