The various fixed setpoints can be selected in two ways:
1. Direct selection:
Precisely one fixed speed setpoint is assigned to each selection signal (e.g. a digital
input). As several selection signals are selected, the associated fixed speed setpoints are
added together to from a total setpoint.
Direct selection is particularly well suited to controlling the motor using the inverter's
digital inputs.
2. Binary selection:
Precisely one fixed speed setpoint is assigned to each possible combination of selection
signals.
Binary selection should preferably be used with a central control and when linking the
inverter to a fieldbus.

The resultant fixed setpoint corresponds
to the parameter values of …
Digital input 3 (DI 3) p1020 = 722.3 p1001
Digital input 4 (DI 4) p1021 = 722.4 p1002
Digital input 5 (DI 5) p1022 = 722.5 p1003
Digital input 6 (DI 6) p1023 = 722.6 p1004
DI 3 and DI 4 p1001 + p1002
DI 3 and DI 5 p1001 + p1003
DI 3, DI 4 and DI 5 p1001 + p1002 + p1003
DI 3, DI 4, DI 5 and DI 6 p1001 + p1002 + p1003 + p1004
