3.5.5 Commissioning the application
After the motor – drive inverter combination was commissioned using the quick or
series commissioning, in the following step parameters should be adapted and set
according to the technological requirements. As an example, the following points
should be considered:
Functional requirements of the drive inverter (e.g. process control with PID
controller)
Limit values
Dynamic requirements
Starting torques
Load surge requirement
Overload
Diagnostics
If the application includes a function, which is not covered by the quick or series
commissioning, then the following sections of the function description or the
parameter list should be considered.
