Loading drive parameters
Inconsistency examples
The 2 adjustment parameters
[Low speed]
(3105-
LSP
) and
[High speed]
(3104-HSP) comply with the consistency rule:
0
y
[Low speed]
(3105-
LSP
)
y
[High speed]
(3104-
HSP
)
y 10000.
Example 1
Initial configuration
V
Configuration to be loaded:
[High speed]
(3104-
HSP
) = 30 Hz
V
[High speed]
(3104-
HSP
) = 60 Hz
[Low speed]
(3105-
LSP
) = 20 Hz
V
[Low speed]
(3105-
LSP
) = 40 Hz
• "Request n: Request writing of
[Low speed]
(3105-
LSP
) to 40 Hz
• "Consistency check: The consistency rule
[Low speed]
(3105-
LSP
)
y
[High speed]
(3104-
HSP
) is not complied with:
- The
[Low speed]
(3105-
LSP
) parameter actually written into the drive is 30 Hz.
• "Request n+1: Request writing of
[High speed]
(3104-
HSP
) = 60 Hz
• "Consistency check: The consistency rules are complied with:
- The
[High speed]
(3104-
HSP
) parameter is correctly written to 60 Hz in the drive.
The configuration loaded is different from the configuration to be loaded:
[Low speed]
(3105-
LSP
) = 30 Hz instead of
[Low speed]
(3105-
LSP
) = 40 Hz
The drive can operate between 30 Hz and 40 Hz, which is not desired.
