Description: Sets the shutdown thresholds for the ground fault monitoring.
The setting is made as a percentage of the maximum power unit current (r0209).
Index: [0] = Threshold for pulse inhibit
[1] = Threshold for pulse enable
Dependency: Refer to: F30021
Note: De-activating the ground fault monitoring:
- Sequence: --> p0287[1] = 0 --> p0287[0] = 0
- independent of the firmware version of the power unit.
Sets the thresholds:
- the prerequisite is at least firmware version 2.2 of the power unit.
Description: Displays the actual, maximum output current of the power unit taking into account de-rating factors.
Description: Sets the response to a thermal overload condition of the power unit.
The following quantities can result in a response to thermal overload:
- heatsink temperature (r0037.0)
- chip temperature (r0037.1)
- power unit overload I2T (r0036)
Possible measures to avoid thermal overload:
- reduce the output current (closed-loop speed/velocity or torque/force control) or the output frequency (V/f control).
- reduce the pulse frequency (only for vector control).
A reduction, if parameterized, is always realized after an appropriate alarm is output.
Values: 0: Reduce output current or output frequency
1: No reduction, shutdown when overload threshold is reached
2: Reduce I_output or f_output and f_pulse (not using I2t)
3: Reduce the pulse frequency (not using I2t)
Dependency: If a sinusoidal filter is parameterized as output filter (p0230 = 3, 4), then only responses can be selected without
pulse frequency reduction (p0290 = 0, 1).
If a fault or alarm is present, then r2135.13 or r2135.15 is set.
