Analog input (ADC)



ADC type
Defines the analog input type and activates the monitoring
function of the analog input.

0 Unipolar voltage input (0 to +10 V)
1 Unipolar voltage input with monitoring

(0 to 10 V)

2 Unipolar current input (0 to 20 mA)
3 Unipolar current input with monitoring

(0 to 20 mA)

4 Bipolar voltage input (-10 to +10 V)
NOTE
For P0756 to P0760, the following applies:
Index 0 : Analog input 1 (ADC1), terminals 3, 4
Index 1 : Analog input 2 (ADC2), terminals 10, 11

P0757 =...

Value x1 of ADC scaling

P0758 =...

Value y1 of ADC scaling
This parameter represents the
value of x1 as a % of P2000
(reference frequency).

P0759 =...

Value x2 of ADC scaling

P0760 =...

Value y2 of ADC scaling
This parameter represents the
value of x2 as a % of P2000
(reference frequency).

Width of ADC deadband
Defines width of deadband on
analog input.
