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 and the motor. The controller is adjusted by changing parameters
which are saved in the memory module. The parameters can be accessed by keypad (diagnosis ter-
minal), by the »EASY Starter« or by the »Engineer«. Access is also possible by a master control via
fieldbus communication. For this purpose, various Communication Units are available, e.g. AS-i,
CANopen, and PROFIBUS.

Danger!
In general, changing a parameter causes an immediate response in the controller!
• This may lead to undesirable behaviour on the motor shaft if the controller has been
enabled!
• Setpoint sources, for instance, may switch over all of a sudden (e.g. when configuring
the signal source 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 in-
hibited. Otherwise, a corresponding error message will be issued.
