Special Functions
Bit0 = Default Configuration
Bit1 = Disable alarm underload current
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
Bit 12 to 15 - Control mode variant selection
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
