Characteristics
Introduction
3.3.2 Access to all information
MOVIDRIVE
®
MDX61B and MOVITRAC
®
B offer digital access to all drive parameters
and functions via the PROFINET interface. The drive inverter is controlled via fast, cyclic
process data. You can use this process data channel to enter setpoints such as the set-
point speed, ramp generator time for acceleration/deceleration, etc. as well as trigger
various drive functions such as enable, control inhibit, normal stop, rapid stop, etc. At
the same time you can also use this channel to read back actual values from the drive
inverter, such as actual speed, current, unit status, error number or reference signals.
3.3.3 Monitoring functions
Using a fieldbus system requires additional monitoring functions for the drive
technology, for example, time monitoring of the fieldbus (fieldbus timeout) or rapid stop
concepts. You can, for example, adapt the monitoring functions of
MOVIDRIVE
®
/MOVITRAC
®
specifically to your application. You can determine, for
instance, which of the drive inverter's error responses should be triggered in the event
of a bus error. A rapid stop makes sense for many applications, although this can also
be achieved by "freezing" the last setpoints so the drive continues operating with the
most recently valid setpoints (such as with a conveyor belt). As the range of functions
for the control terminals is also guaranteed in fieldbus mode, you can continue to
implement rapid stop concepts using the terminals of the drive inverter, irrespective of
the fieldbus used.
3.3.4 Diagnostics
The MOVIDRIVE
®
drive inverter and the MOVITRAC
®
B frequency inverter offer you
numerous diagnostics options for startup and service. For example, you can use the in-
tegrated fieldbus monitor to control setpoint values sent from the higher-level controller
as well as the actual values. The integrated Web server allows you to access the diag-
nostic values using a standard browser.
3.3.5 Fieldbus monitor
Furthermore, you are supplied with a variety of additional information about the status
of the fieldbus interface. The fieldbus monitor function in conjunction with the
MOVITOOLS
®
MotionStudio PC software offers you an easy-to-use diagnostic tool for
setting all drive parameters (including the fieldbus parameters) and for displaying the
fieldbus and device status information in detail.
