Fig. 61 shows the S5-program of this application example. First the inputs E 32.2 ... E32.6 for the
control of the relay via output A 34.0 are connected via AND-relation in the function component FB10.
Then the inverter receives the setpoint specification dependent on input E1.2.
Actual control of the inverter starts from the STEU jump flag via the digital input E1.1, which triggers
the control commands
Enable and Stop.
