This parameter defines the drive operating mode. Pr xx.00 must be set
to 1253 (European defaults) or 1254 (USA defaults) before this
parameter can be changed. When the drive is reset to implement any
change in this parameter, the default settings of all parameters will be
set according to the drive operating mode selected and saved in
memory.
6.2.9 Status information
0.49 {11.44} Security status
RW Txt
0 to 2
This parameter controls access via the drive keypad as follows:
Value String
0 L1 Only menu 0 can be accessed
1 L2
Lock user security when drive is reset.
2 Loc
(This parameter is set to L1 after reset.)
The keypad can adjust this parameter even when user security is set.
0.50 {11.29} Software version number
RO Uni
1.00 to 99.99
The parameter displays the software version of the drive.
0.51 {10.37} Action on trip detection
RW Uni
0 to 15
Each bit in this parameter has the following functions:
Bit
0 Stop on non-important trips
1 Disable braking IGBT trips
2 Disable phase loss trip (Unidrive SP size 0 only)
Disable braking resistor temperature monitoring failure
3
detection. (Unidrive SP size 0 only)
Example
Pr 10.37=8 (1000 ) br.th trip is disabled
binary
Pr 10.37=12 (1100 ) br.th and phase loss trip is disabled
binary
Stop on non-important trips
If bit 0 is set to zero then the drive simply trips when a non-important trip
occurs. Non-important trips are: th, ths, Old1, cL2, cL3, SCL. If bit 0 is
set to one the drive will stop before tripping when one of these trips is
initiated, except in Regen mode where the drive trips immediately.

Disable braking IGBT trips
For details of braking IGBT trip mode see Pr 10.31.
Disable phase loss trip (size 0 only)
The user can disable the phase loss trip in 200V size 0 drives as these
are allowed to operate from a single phase supply. If bit 2 is set to zero
the phase loss trip is enabled. If bit 2 is set to one the phase loss trip is
disabled in 200V size 0 drives only.
Disable braking resistor temperature monitoring failure detection
(size 0 only)
Size 0 drives have an internal user install braking resistor with a
thermistor to detect overheating of the resistor. As default bit 3 of Pr
10.37 is set to zero, and so if the braking resistor and its thermistor is not
installed the drive will produce a trip (br.th) because the thermistor
appears to be open-circuit. This trip can be disabled so that the drive can
run by setting bit 3 of Pr 10.37 to one. If the resistor is installed then no
trip is produced unless the thermistor fails, and so bit 3 of Pr 10.37 can
be left at zero. This feature only applies to size 0 drives. For example if
Pr 10.37 = 8, then br.th trip will be disabled.
