3.8.7. 6-5* Analog Output 1
Parameters for configuring the scaling and limits for analog output 1, i.e. Terminal 42. Analog outputs are current outputs: 0/4 – 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 analog output
is 12 bit.
6-50 Terminal 42 Output
Option:
[0] No operation
* Output frequency
[100]
[101] Reference
[102] Feedback
[103] Motor current

Function:
Sets the analog input scaling value to correspond to the low reference/feedback value set in par. 6-44.
Function:
Sets the analog input scaling value to correspond to the high reference/feedback value set in par. 6-45.
Function:
Sets the analog input scaling value to correspond to the low voltage value set in par. 6-40.
Function:
Sets the analog input scaling value to correspond to the high voltage value set in par. 6-41.
Function:
A 1 st order digital low pass filter time constant for suppressing electrical noise on terminal X30/12.
Par. 6-46 cannot be changed while the motor is running.
Function:
This parameter makes it possible to disable the Live Zero monitoring. E.g. to be used if the analog outputs are
used as part of a decentral I/O system (e.g. when not part of any frequency converter related control functions,
but feeding a Building Management System with data)
Function:
Select the function of Terminal 42 as an analog current output.
: 0 - 100 Hz
: Minimum reference - Maximum reference
: -200% to +200% of par. 2-14
: 0 - Inverter Max. Current (par. 16-37)
