6.4
Verification of Parameter Adjustment
All MOVITRAC
®
31.. frequency inverter parameters can be read or written via both the serial interface
and the fieldbus interface. Thus either the hand-held keypad or the MC_SHELL PC program can be
used for checking the adjustment of parameters via the fieldbus system.
It is consequently possible to use the serial interface to read and check parameters written using the
fieldbus, for example. The
MOVITRAC
®
31.. Parameter List provides co-ordination between the
hand-held keypad menu number and the parameter index.
In principle, no verification is necessary, since the inverter responds with an appropriate error
message if parameters have been wrongly adjusted (see also Section 5.5).

Information about the Fieldbus Option PCB
Further information about the fieldbus option pcb is provided by fieldbus monitor parameters P070
- P073.
6.5.1
Process Data Configuration
The fieldbus monitor parameter
P070 Process Data Configuration shows how many process data
words are used for inverter control, and whether the parameter channel is used. This parameter is
either set with a hardware switch on the fieldbus option pcb, or via the fieldbus master during bus
system start-up (e.g. with PROFIBUS-DP).
6.5.2
Fieldbus Option PCB Type
The fieldbus monitor parameter
P071 Fieldbus Type shows which fieldbus system will be supported
by the fieldbus option pcb used. Because the fieldbus interface on the MOVITRAC
®
31.. frequency
inverter is universal, this parameter is for information only.
6.5.3
Fieldbus Baud Rate
The
P072 Fieldbus Baud Rate parameter shows the fieldbus baud rate in [kbaud]. Depending on the
fieldbus system used, adjustment can either be made with a hardware switch on the fieldbus option
pcb or via automatic baud rate detection. If the baud rate cannot be detected, the value 0.00 is
displayed.
6.5.4
Fieldbus Address
The
P073 Fieldbus Address parameter shows the actual fieldbus station address of the inverter.
Adjustment of this address is carried out using a hardware switch on the fieldbus option pcb (see
the User Manual for the option pcb).
This parameter will be set at 0 for fieldbus systems which do not need station addressing.
