All control methods are available without any changes in the hardware or software.
The control mode of inverter is selected by parameter P1.1.11 Input set, which has eight alternative
settings: MS2 (stop-limit), MS2/MS3 (slow-limit), EP2 (stop-limit), EP2 (slow-limit), EP3, MS4, MS5 and
AU (automation control). (See Chapter 5: parameter descriptions.) The parameter assigns digital inputs
S1, S2 and DID3-DID5. It is not possible to change the functions of the inputs separately. Digital inputs
DID1 and DID2 are for direction commands, so DID1 = S1, DID2 = S2 in every case. Digital inputs (DID3-
DID5) are automatically assigned according to the selected mode. In mode MS5, the MAX speed will be
activated when DID4 is off and DID5 is still on. The state of inputs can be checked from parameter V2.3.
