Process input data
The following table shows the process input data from the inverter to the higher-level controller for control via fieldbus with 8 process data words.
Word | Bit | Function | |
|---|---|---|---|
PI 1 | Status word | 0 | "1": Ready |
1 | "1": STO inactive | ||
2 | "1": Output stage enable | ||
3 | "1": Brake released | ||
4 | "1": Motor running | ||
5 | "1": Active drive referenced | ||
6 | "1": New relative position applied | ||
7 | "1": "In position" signal active | ||
8 | "1": Fault | ||
9 | "1": Warning "Warning" can be defined as a fault response to certain faults. If a warning is signaled, both bit PI 1.9 and the associated fault code are indicated in PI 3. If a warning and a fault are active at the same time, only bit PI 1.8 is set and the respective fault code is indicated in PI 3. | ||
10 | "1": Drive train 2 active | ||
11 | "1": "Setpoint/actual speed comparison active" signal | ||
12 | "1": Software limit switches inactive | ||
13 | "1": Reserved (can be assigned individually using status word 2, bit 13) | ||
14 | "1": Standby mode active | ||
15 | MOVIKIT® Handshake Out (for details, see MOVIKIT® Handshake In) | ||
PI 2 | Actual speed | 0 – 15 | User unit |
PI 3 | Status Fault-subfault | 0 – 15 |
(High byte: fault; Low byte: subfault) INFORMATION: The device reads the fault code of the inverter or inverter option via the parameter channel. Fault number "106.00" is displayed until the fault is determined. As soon as the inverter fault code is available, the fault number changes to the actual fault code of the inverter. To log faults in the higher-level controller, it is recommended to query the change of the fault code instead of the fault bit edge. For more information, refer to the product manual of the respective device. |
PI 4 | Actual torque | 0 – 15 | Actual torque |
PI 5 | Digital inputs | 0 | DI 00 |
1 | DI 01 | ||
2 | DI 02 | ||
3 | DI 03 | ||
4 | DI 04 | ||
5 | DI 05 | ||
PI 6 | Actual application mode (operating mode) | 0 – 15 | Operating mode. See chapter Operating modes. |
PI 7 | Actual position (high word) | 0 – 15 | User unit |
PI 8 | Actual position (low word) | 0 – 15 | User unit |
