ID Parameter CL Setting range
[Default]
Description
5815 Hysteresis lower
voltage limit 2 0 to 50%
[2%]
If the mains voltage has fallen
below the limit configured in
parameter
╚═▷ 5811 , the voltage
must exceed the limit and the
value configured here, to be
considered as being within the
operating limits again.
5812 Upper frequency limit 2 66.7¹ to 150.0%
[110.0%]
The maximum permissible
positive deviation of the mains
frequency from the rated system
frequency (parameter
╚═▷ 1750 )
is configured here.
This value may be used as a
frequency limit switch. The
conditional state of this switch
may be used as a command
variable for the LogicsManager
(02.10).
Notes
¹ The lowest measurable
frequency is 40 Hz.
66.7 % of 60 Hz is 40 Hz.
Equivalent for 50 Hz don't go
below 80 %.
5816 Hyst. upper
frequency limit 2 0.0 to 50.0%
[0.5%]
If the mains frequency has
exceeded the limit configured in
parameter
╚═▷ 5812 , the
frequency must fall below the limit
and the value configured here, to
be considered as being within the
operating limits again.
5813 Lower frequency limit 2 66.7¹ to 100.0%
[90.0%]
The maximum permissible
negative deviation of the mains
frequency from the rated system
frequency (parameter
╚═▷ 1750 )
is configured here. This value may
be used as a frequency limit
switch. The conditional state of
this switch may be used as a
command variable for the
LogicsManager (02.10).
Notes
¹ The lowest measurable
frequency is 40 Hz.
66.7 % of 60 Hz is 40 Hz.
Equivalent for 50 Hz don't go
below 80 %.
5817 Hyst. lower
frequency limit 2 0.0 to 50.0%
[0.5%]
If the mains frequency has
exceeded the limit configured in
parameter
╚═▷ 5813 , the
frequency must raise above the
limit and the value configured
here, to be considered as being
within the operating limits again.
