different triggering times (<5 s, <10 s and <20 s) can be set. The trigger times are based on
classes 5, 10 and 20 for semiconductor switching devices. The recommended setting for standard
applications is P535=5.
All curves run from 0 Hz to half of the nominal motor frequency (P201). The full nominal current is
available from half of the nominal frequency upwards.
With multi-motor operation the monitoring must be disabled.
