For each transfer all the data errors are flagged, and a counter is
incremented for each transfer error. Note that the error counter is
allowed to rollover and is reset when the PROFIBUS board is
configured. When writing data outside the normal range of a
parameter, the data is clamped to the maximum or minimum value.
Bit parameter values outside the normal range are ignored.
For example if the following information was viewed:
P74.44 = 0300H (= 0000 0011 0000 0000 binary)
P74.45 = 21
This indicates that one of the monitor parameters configured
attempted to read from a non-existent parameter, and another
parameter attempted to read a parameter that did not have Fieldbus
read access. The error counter indicates that a total of 21 errors
had occurred since the last PROFIBUS configuration.
Note that entering a zero as a monitor parameter to be read or
written will not produce an error.
7.4.12 Reference holders P74.20 to P74.38
The PROFIBUS module can provide up to 10 references for use
within the drive. These references can be used to control such
values as the speed (if pointed to by one of the speed reference
pointers). The PROFIBUS reference module needs to be used in
conjunction with Menu 42 (the Pointer Menu), which is described in
Section 6 of the Software Technical Manual T1679.
WARNING:
Ensure that no two Fieldbus parameters are mapped to the
same Drive parameter as this will lead to unpredictable
results.
