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)
Value x1 for the analog output
p4077[0]
characteristic
Setting for the x coordinate in % of the first point on the scaling characteristic.
Value y1 for the analog output
p4078[0]
characteristic
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.
