Index: r0755[0] : IN000 Analog input 1 (ADC 1) r0755[1] : IN001 Analog input 2 (ADC 2)
Note: This value is used as an input to analog BICO connectors.
ASPmax represents the highest analog setpoint (this may be at 10V)
ASPmin represents the lowest analog setpoint (this may be at 0V)
Details: See parameters P0757 to P0760 (ADC scaling)
P0756[2] Type of ADC
Min: 0 Def: 0 Max: 5
Level 2
Data: Defines type of analog input and also enables analog input monitoring. #if defined ECB || defined VCB To switch
over from voltage to current analog input it is not sufficient to merely modify parameter P0756. Rather, the DIPs
on the terminal board must also be set to the correct position. The DIP settings are as follows:
- OFF=voltage input (10V)
- ON =current input (20 mA)
Allocation of DIPs to analog inputs is as follows:
- DIP on left (DIP 1)= Analog input 1
- DIP on right (DIP 2)= Analog input 2
Enum: 0=Unipolar voltage input (0 to +10V)
1=Unipolar voltage input with monitoring (0 to 10V)
2=Unipolar current input (0 to 20 mA)
3=Unipolar current input with monitoring (0 to 20 mA)
4=Bipolar voltage input (-10V to +10V)
5=LG NI1000 sensor input
Index: P0756[0] : IN000 Analog input 1 (ADC 1) P0756[1] : IN001 Analog input 2 (ADC 2)
Dependency: Function disabled if analog scaling block programmed to output negative setpoints (see P0757 to P0760).
Note: When monitoring is enabled and a deadband defined (P0761), a fault condition will be generated (F0080) if the
analog input voltage falls below 50% of the deadband voltage. #if defined ECB || defined VCB On account of h/w
restirction it is not possible to select the bipolar voltage (see Enum declaration) for analog input 1 (P0756[1]=4).
Details: See P0757 to P0760 (ADC scaling).
P0757[2] Value x1 of ADC scaling [V/mA]
Min: 50.0 Def: 0 Max: 150.0
Level 2
Data: Parameters P0757-P0760 configure the input scaling where:
Analog setpoints represent a [%] of the normalized frequency in P2000.
Analog setpoints may be larger than 100%
ASPmax represents highest analog setpoint (this may be at 10V).
ASPmin represents lowest analog setpoint (this may be at 0V).
Default values provide a scaling of 0V=0%, and 10V=100%.
Index: P0757[0] : IN000 Analog input 1 (ADC 1) P0757[1] : IN001 Analog input 2 (ADC 2)
P0758[2] Value y1 of ADC scaling
Min: -99999.9 Def: 0.0 Max: 99999.9
Level 2
Index: P0758[0] : IN000 Analog input 1 (ADC 1) P0758[1] : IN001 Analog input 2 (ADC 2)
Dependency: Affects P2000 to P2003 (reference frequency, voltage, current or torque) depending on which setpoint is to be
generated.
