6.5 Parameters: 6-** Analog In/Out
6.5.1 6-5* Analog Output 1
Parameters for configuring analog output 1, i.e. Terminal
42. Analog outputs are current outputs: 0/4 to 20 mA.
Common terminal (terminal 39) is the same terminal and
has the same electrical potential for analog common and
digital common connection. Resolution on the analog
output is 12 bit.
6-50 Terminal 42 Output
Option: Function:
[0] * No
operation
No signal is provided on the analog output.
[103] Current Signal represents the unit current. The
inverter max. current (taken from parameter
16-37 Inv. Max. Current) is equal to 20 mA.
[106] Power Signal represents the unit power. The unit
nominal power (taken from parameter 15-41
Power Section) is equal to 20 mA.
[133] Current
4-20mA
Signal represents the unit current with 0
equal to 4 mA. The inverter max. current
(taken from parameter 16-37 Inv. Max.
Current) is equal to 20 mA.
[136] Power
4-20mA
Signal represents the unit power with 0
equal to 4 mA. The unit nominal power
(taken from parameter 15-41 Power Section)
is equal to 20 mA.
6-51 Terminal 42 Output Min Scale
Range: Function:
0 %* [0 - 200
%]
Scale for the minimum output (0 or 4 mA) of
the analogue signal at terminal 42.
Set the value to be the percentage of the full
range of the variable selected in 6-50 Terminal
42 Output.
6-52 Terminal 42 Output Max Scale
Range: Function:
100%* [0.00 –
200%]
Scale the maximum output of the selected
analog signal at terminal 42. Set the value to
the maximum value of the current signal
output. Scale the output to give a current
lower 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, programme 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%), calculate the percentage value
as follows:
