Parameter Value Adjustment range
p4078[1] Analog outputs, characteristic value y1 -20.000 to +20.000 V or mA
Factory setting: 0.000 mA
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 Value Adjustment range
p4079[1] Analog outputs, characteristic value x2 -1000.00 to +1000.00%
Factory setting: 100.00 %
Setting for the x coordinate in % of the second point on the scaling characteristic.
Parameter Value Adjustment range
p4080[1] y2 of the characteristic of the analog out‐

-20.000 to +20.000 V or mA
Factory setting: 20.000 mA
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.
