8.4 Further Settings for Analog Outputs
Description
The customer terminal block (–A60) features two analog outputs for outputting
setpoints via current or voltage signals.
In addition to the settings described in Chapter 8.2, a function for scaling output
signals is available.

Additional Setting Parameters for Analog Output 0 (AO0)
Setting range: -1000.00 ... +1000.00 %
p4077[0]
Value x1 for the analog output
characteristic
Factory setting: 0.00 %
Setting for the x coordinate in % of the first point on the scaling characteristic.
Setting range: -20.000 ... +20.000 V or mA
p4078[0]
Value y1 for the analog output
characteristic
Factory setting: 0.000 mA
Setting for the y coordinate in V or mA of the first point on the scaling characteristic.
The unit is V when analog output 0 is set as a voltage output (p4076[0] = 1 / 4) and terminals X522: 1
and 2 are used.
The unit is mA when analog output 0 is set as a current output (p4076[0] = 0 / 2 / 3) and terminals X522:
3 and 2 are used.
