NOTE:
Although the resolution of this setpoint is 0.01s, in fact the adjusted delay is
rounded to the next higher multiple of the period of the bus voltage. The
period is either 0.02s for 50Hz systems or 0.0166s for 60Hz systems. E.g. if
the delay is set to 0.03s at 50Hz system the real delay will be 0.04s.
12.2.7.5 Setpoint: BusRfreq prot
This setpoint enables or disables BusR frequency protection. For more
information on this protection see setpoints BusRight >f, BusRight <f and
BusRight f del.
NOTE:
If both voltage and frequency protections (see also setpoint BusRVolt prot)
are disabled there is no way for the controller to decide whether the busR is
healthy or not. In this case busR is considered healthy if there is any voltage.
12.2.7.6 Setpoint: BusRight >f
This setpoint determines the treshold for busR overfrequency protection. This
protection is evaluated with delay given by setpoint BusRight f del and it is
history record type.
12.2.7.7 Setpoint: BusRight <f
