355 Terminal 26, digital output
(DO 26 FUNCTION)
Value:
See table in section Digital and relay outputs.
Function:
The digital outputs shift from 0 V to 24 V
when the output is true.
Description of choice:
See description in section Digital relay outputs.
356 Terminal 26, output, pulse scaling
(DO 26 FUNCTION)
Value:
1 - 50000 Hz
✭
5000 Hz
Function:
This parameter allows scaling of the pulse output signal.
Description of choice:
Set the desired value.
357 Terminal 42, Output minimum scaling
(OUT 42 SCAL MIN)
359 Terminal 45, Output minimum scaling
(OUT 45 SCAL MIN)
Value:
000 - 100%
✭
0%
Function:
These parameters are to scale the minimum output of
the selected analog signal on terminals 42 and 45.
Description of choice:
The minimum value is to be scaled as a percentage
of the maximum signal value, i.e. 0mA (or 0 Hz)
is desired at 25% of the maximum output value,
and then 25% is programmed.
The value can never be higher than the corresponding
setting of Output maximum scaling if this
value is below 100%.
358 Terminal 42, Output maximum scaling
(OUT 42 SCAL MAX)
360 Terminal 45, Output maximum scaling
(OUT 45 SCAL MAX)
Value:
000 - 500% ✭
100%
Function:
These parameters are to scale the maximum output of
the selected analog signal on terminals 42 and 45.
Description of choice:
Set the value to the desired maximum value
of the current signal output.
Maximum value:
The output can be scaled to give a lower current
than 20 mA at full scale or 20 mA at an output
below 100% of the maximum signal value.
If 20 mA is the desired output current at a value
between 0 - 100% of the full-scale output, program the
percentage value in the parameter, i.e. 50% = 20 mA.
If a current between 4 and 20 mA is desired at
maximum output (100%), the percentage value to
program in the drive is calculated as:
