P0756[2] Type of analog input Level 2

Min: 0 Def: 0 Max: 5

Unit: -

Details:

Defines type of analog input and also enables analog input monitoring.

To change from a voltage to a current analog input, modify parameter P0756 as

well as set I/O module DIP switches to the appropriate position. The DIP switch

settings are as follows:

- OFF=voltage input (10V)

- ON=current input (20 mA)

Allocation of DIP switches to analog inputs is as follows:

- DIP switch on left (DIP1)=Analog input 1

- DIP switch on right (DIP2)=Analog input 2

Enum:

0 Unipolar voltage input (0V to +10V)

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

2 Unipolar current input (0 mA to 20 mA)

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

5 L+S NI1000 sensor input

Index:

P0756[0]: Analog input 1 (AI1)

P0756[1]: Analog input 2 (AI2)

Dependency:

This function is disabled if the analog scaling block is programmed to output

negative setpoints (see P0757 to P0760 for analog input scaling).

Note:

When monitoring is enabled and a deadband is defined (P0761), a fault condition

will be generated (F0080) if the analog input voltage falls below 50% of the

deadband voltage.

When using a value of 5, any PID setpoint needs to be in degrees C.

Reference:

See P0757 to P0760 (analog input scaling).
