2 Parameters
2.2 List of parameters
p0287[0...1] Ground fault monitoring threshold / Gnd flt threshold
VECTOR_G Can be changed: T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.0 [%]
Description: Sets the shutdown thresholds for the ground fault monitoring.
The setting is made as a percentage of the maximum current of the power unit (r0209).
Index: [0] = Reduced at the start of precharging
[1] = Regular
Dependency: Refer to: F30021
Note: The parameter only applies to booksize and chassis power units.
Deactivating the ground fault monitoring:
- Sequence: --> p0287[1] = 0 --> p0287[0] = 0
- irrespective of the firmware version of the power unit.
Sets the thresholds:
- the prerequisite is at least firmware version 2.2 of the power unit.
r0289 CO: Maximum power unit output current / PU I_outp max
VECTOR_G Can be changed: -
Data type: FloatingPoint32
P-Group: Displays, signals
Not for motor type: -
Min
- [Arms]
Description: Displays the actual maximum output current of the power unit taking into account derating factors.
p0290 Power unit overload response / PU overld response
VECTOR_G Can be changed: T
Data type: Integer16
P-Group: Converter
Not for motor type: -
Min
0
Description: Sets the response to a thermal overload condition of the power unit.
The following quantities can result in a response to thermal overload:
- heat sink temperature (r0037[0]).
- chip temperature (r0037[1]).
- power unit overload I2t (r0036).
Possible measures to avoid thermal overload:
- reduce the output current limit r0289 and r0067 (for closed-loop speed/velocity or torque/force control) or the output
frequency (for U/f control) indirectly via the output current limit and the intervention of the current limiting controller).
- reduce the pulse frequency.
A reduction, if parameterized, is always realized after an appropriate alarm is output.
