PI 4

Menu: 4.3.1-2.4

Description

When the Update parameter is activated, the values indicate the current process input data.

When the Update parameter is deactivated, the last values of the process input data are maintained or can be specified manually. The locally specified value is stored in volatile memory. The local value is reset to the default value after the inverter is switched off and on again.

The following parameters are set:

Parameter	Meaning
Source	Specifies the data assigned to the process input data words. Process input data words with a word width of 32 bits can be reduced to a 16 bit value by means of the following data formats: Saturated to 16 bits: The internal 32 bit value is limited to a 16 bit value. When this value exceeds the value range of the 16-bit value, then no overflow occurs but the maximum value is limited. This prevents a maximum positive value from changing to a maximum negative value. Low word: Lower 16 bits of the 32‑bit value High word: Upper 16 bits of the 32‑bit value
Value	Value of the data source
