Bit2 - Disable alarm overload current
Bit3-4 Parameterization configuration
Bit 5 - Ignore Phase loss during start phase
Bit 6 - Ignore earth fault during start phase
Bit 7 - Ignore Unbalance load during start
phase
Bit 8 to 11- Typical selection

Description
0-Disable
Time interval between analog value log
samples
Example: If set to 60 - every 60 secs a
sample is recorded
Trigger mechanism
Number of pre and post trigger samples
recorded.
Time allowed between Modbus messages until
Modbus error is generated
If set to 1 - typical and control mode default
configuration will be used.
0 0 - parameterization allowed via Profibus DP
only when motor is in stop condition
0 1 - parameterization allowed via Profibus DP
while motor is at any state.
1 0 - parameterization allowed via Profibus
DP when draw out position is not in test or
operation mode
11 - parameterization allowed via Profibus
DP when the operation mode is not Remote
or Local. Note: the Modbus operation mode
selection is done using function code 05 -
commands 10 or 11
1 - Ignored phase loss during start-up
0 - Do not ignore
1 - Ignored earth fault during start-up
0 - Do not ignore
1 - Ignored current unbalance during start-up
