Programming Guide
the parameter, for example 50% = 20 mA. If a current 4–20 mA is required at maximum output (100%), calculate the percentage
value as follows (example where required maximum output is 10 mA):

Parameter 6-73 Terminal X45/1 Bus Control
Table 439: Parameter 6-73 Terminal X45/1 Bus Control
6-73 Terminal X45/1 Bus Control
Default value: 0%
Conversion index: -2
Holds the level of analog output 3 (terminal X45/1) if controlled by bus.
Parameter 6-74 Terminal X45/1 Output Timeout Preset
Table 440: Parameter 6-74 Terminal X45/1 Output Timeout Preset
6-74 Terminal X45/1 Output Timeout Preset
Default value: 0%
Conversion index: -2
Holds the preset level of analog output 3 (terminal X45/1). If there is a fieldbus timeout and a timeout function is selected in param-
eter 6-70 Terminal X45/1 Output, the output is preset to this level.
5.7.9 6-8* Analog Output 4 MCB 113
Parameters for configuring the scaling and limits for analog output 4, terminals X45/3 and X45/4. Analog outputs are current out-
puts: 0/4–20 mA. Resolution on analog output is 11 bit.
Parameter 6-80 Terminal X45/3 Output
Table 441: Parameter 6-80 Terminal X45/3 Output
6-80 Terminal X45/3 Output
Default value: [0] No operation
Conversion index: –
Select the function of terminal X45/3 as an analog current output.
