Qualitative utilization level of the inverter using function mod-
The computational performance of the inverter is designed for typical inverter applications.
Every configured function module uses part of the computational performance of the inverter.
If you enable all of the inverter function modules, then the inverter responds with a fault,
because its available computational performance is exceeded.
Only configure function modules that you actually require for your particular application.

Encoders for position control
The inverter can evaluate a second encoder for the position control. You can find information
about the position control in the "Basic positioner" function manual.
