2 Introduction: Parameterising the controller
Being a component of a machine which includes a speed-variable drive system, the controller needs
to be adjusted to its drive task. The controller is adjusted by changing parameters which are saved
in the memory module. The parameters can be accessed by keypad, by the »EASY Starter« or by the
»Engineer«. Access is also possible by a master control via fieldbus communication. For this purpose,
the "CAN on board" CAN interface and the MCI interface for using a communication module (e.g.
PROFIBUS) are available.

Danger!
In general, changing a parameter causes an immediate response in the controller!
An enabled controller can cause an unwanted behaviour at the motor shaft! For
instance, setpoint sources can change over abruptly (e.g. when the signal source is
configured for the main setpoint).
Certain device commands or settings which may cause critical states of drive behaviour
constitute exceptions. Such parameter changes are only possible if the controller is
inhibited. Otherwise, a corresponding error message will be issued.
