P0756
Defines the type of analog input and enables analog input monitoring.
Possible settings:
0 Unipolar voltage input (0 to 10 V) (factory setting).
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).
5 LG-Ni 1000 sensor input (–10 to +10 V).
Important: The parameter setting must match the setting of the 2 DIP switches on
the I/O module.
Index:
P0756[0] : Analog input 1 (ADC 1).
P0756[1] : Analog input 2 (ADC 2).
Note on dependency:
This function is disabled if the analog scaling block is programmed to negative output
setpoints (see P0757 to P0760).
Note on the monitoring function
If monitoring is enabled and the dead zone is defined (P0761), an error message
appears (F0080) as soon as the analog input voltage drops below 50% of the dead
zone voltage.
P0753
Defines the filter time in ms for the analog input.
Setting range: 0 to 10,000 ms
Factory setting: 100 ms
Index:
P0753[0] : Analog input 1 (ADC 1).
P0753[1] : Analog input 2 (ADC 2).
Note:
Increasing this time reduces (smoothes) the ripples but also slows down the response
to the analog input.
P0757 – P0760
Parameters P0757 to P0760 are used to configure the input scaling for the analog
inputs according to the following curve:
