Introduction

The process data and drive parameters can be sent synchronously or asynchronously with a
synchronization message.

The use of a fieldbus system in drive technology requires additional monitoring functions, such as
fieldbus timeout or special emergency stop concepts. The monitoring functions of the
MOVIDRIVE
®
can be matched to the specific application for which it is to be used. This feature
enables you, for instance, to specify which response the drive inverter should trigger if an error
should occur in the bus. A rapid stop will be practical for many applications, but it is also possible
to freeze the last setpoints, so that the drive can continue with the last valid setpoints (e.g. con-
veyor belt). As the functionality of the control terminals is also ensured when the drive inverter is
operated in the fieldbus mode, fieldbus-independent emergency stop concepts can still be imple-
mented via the drive inverter’s terminals.
The MOVIDRIVE
®
drive inverter offers numerous diagnostic facilities for commissioning and
servicing. The MX_SHELL software offers even more convenient diagnostic facilities in that it
provides a detailed display of the fieldbus and inverter status as well as the facility to set all the
drive parameters (including the fieldbus parameters).
