Control word 2
Control word 2 contains the function bits for the most important drive functions in the basic control block; the virtual input terminals in the higher-order part. These are freely-programmable input terminals that are not physically available due to missing hardware (option cards). In this way, the input terminals are represented on the virtual input terminals of the fieldbus. Each virtual terminal is assigned to an optional and physically unavailable input terminal. Its functionality can be programmed as required.
Bit | Function | Definition |
|---|---|---|
0 | Controller inhibit "1" / enable "0" | Fixed definition |
1 | Enable "1" / rapid stop "0" | |
2 | Enable "1" / stop "0" | |
3 | Reserved | |
4 | Integrator switchover | |
5 | Parameter set switchover | |
6 | Reset | |
7 | Reserved | |
8 | Virtual terminal 1 = P610 / digital input DI10 | Virtual input terminals |
9 | Virtual terminal 2 = P611 / digital input DI11 | |
10 | Virtual terminal 3 = P612 / digital input DI12 | |
11 | Virtual terminal 4 = P613 / digital input DI13 | |
12 | Virtual terminal 5 = P614 / digital input DI14 | |
13 | Virtual terminal 6 = P615 / digital input DI15 | |
14 | Virtual terminal 7 = P616 / digital input DI16 | |
15 | Virtual terminal 8 = P617 / digital input DI17 |
NOTICE
If the FIO21B option is plugged into the frequency inverter in addition to the fieldbus interface, then the inputs of the FIO21B option have priority. In this case, the virtual inputs are not evaluated.
