5.13.2 - Explanation of parameters in menu 12
: Comparator 1 output
: Comparator 2 output
Adjustment range : Disabled (0) or Enabled (1)
Disabled (0):
The input variable is less than or equal to the
comparator threshold.
Enabled (1):
The input variable is greater than the comparator
threshold.
: Comparator 1 source
Adjustment range :
00.00
to
21.51
Factory setting
:
00.00
This parameter defines the variable which is to be compared
to the configured threshold.
The absolute value of the variable is taken into account.
: Comparator 1 threshold
Adjustment range : 0 to 100.0%
Factory setting
: 0
This parameter is used to adjust the comparator trip
threshold.
The threshold is expressed as a percentage of the maximum
value of the compared variable.
: Comparator 1 hysteresis
Adjustment range : 0 to 25.0%
Factory setting
: 0
This parameter defines the window within which the
comparator output will not change state.
The output will change to Enabled (1) when the variable
reaches the threshold value + (hysteresis/2).
The output will change to Disabled (0) when the variable
drops below the threshold value - (hysteresis/2).
The hysteresis is expressed as a percentage of the maximum
value of the compared variable.
: Comparator 1 output invert
Adjustment range : Disabled (0) or Enabled (1)
Factory setting
: Disabled (0)
This parameter is used to invert the comparator output.
Disabled (0): Output not inverted.
Enabled (1):
Output inverted.
: Comparator 1 output destination
Adjustment range :
00.00
to
21.51
Factory setting
:
00.00
This parameter defines the internal parameter which will be
assigned by the comparator output.
Only bit type parameters can be programmed.
If an unsuitable parameter is programmed, the output is not
sent anywhere.
: Function 1 variable 1 source
Adjustment range :
00.00
to
21.51
Factory setting
:
00.00
This parameter defines the source parameter for variable 1 to
be processed.
Only "numerical" parameters can be assigned.
If an unsuitable parameter is selected, the value of the
variable will be 0.
: Function 1 variable 2 source
Adjustment range :
00.00
to
21.51
Factory setting
:
00.00
This parameter defines the source parameter for variable 2 to
be processed.
Any "numerical" parameter can be assigned.
If an unsuitable parameter is selected, the value of the
variable will be 0.
: Function block 1 select
Adjustment range : See table below
Factory setting
: O = V1 (0)
This parameter is used to define the function of the internal
variables processing block.

uals 2, 3, 4 or 5:
When the result of the calculation is greater than or equal to
32767, the output
12.11
or
12.31
is limited at 32767.
When the result of the calculation is less than or equal to
-32768, the output
12.11
or
12.31
is limited at -32768.
• If

12.30
e
q
uals 5:
To avoid a calculation error if V2 = 0, the result of the
operation will be 0.
• If

12.30
e
q
uals 9:
To avoid a calculation error, it is the absolute value of the
signal V1 which is taken into account before calculating its
square root or cube root.
