Operation
8.5 Functions
Parameter
p4078[1]
Setting for the y coordinate in V or mA of the first point on the scaling characteristic.
When analog output 1 is set as a voltage output (p4076[1] = 1 / 4) and terminals X522: 6,5 are used, the
unit is V.
When analog output 1 is set as a current output (p4356[1] = 0 / 2 / 3) and terminals X522: 4,5 are used,
the unit is mA.
Parameter
p4079[1]
Setting for the x coordinate in % of the second point on the scaling characteristic.
Parameter
p4080[1]
Setting for the y coordinate in V or mA of the second point on the scaling characteristic.
When analog output 1 is set as a voltage output (p4076[1] = 1 / 4) and terminals X522: 6,5 are used, the
unit is V.
When analog output 1 is set as a current output (p4356[1] = 0 / 2 / 3) and terminals X522: 4,5 are used,
the unit is mA.
Example: Changing analog output 0 from current to voltage output ± 10 V and setting the characteristic
