Function compatibility table

Configurable I/O Functions which are not listed in this table are fully compatible. Stop functions have priority over run commands. The selection of functions is limited by: The number of drive I/O The incompatibility of certain functions with one another

Functions Summing inputs +/- speed Limit switch management Preset speeds PI regulator Jog operation Brake sequence DC injection stop Fast stop Freewheel stop Summing inputs


+/- speed Limit switch management Preset speeds


PI regulator Jog operation


Brake sequence DC injection stop


Fast stop


Freewheel stop


Incompatible functions Priority functions (functions which cannot be active at the same time) Compatible functions


The arrow indicates which function has priority Not applicable


Example: the Freewheel stop function has priority over the Fast stop function



AOC/AOV analog outputs The same data is available on analog outputs AOC and AOV. The following assignments are possible: Motor current Motor frequency Motor torque Power supplied by the drive Drive detected fault Frequency threshold reached High speed reached Current threshold reached Frequency reference reached Motor thermal threshold reached Brake sequence Adjusting analog outputs AOC/AOV modifies the characteristics of the current analog output AOC or the voltage analog output AOV. AOC: can be set as 0-20 mA or 4-20 mA AOV: can be set as 0-10 V Saving and retrieving the configuration It is possible to save a configuration. This function is used to store a drive configuration in addition to the current configuration. Retrieving this configuration clears the current configuration.
