Example:
Case a:
ASPmin = 300 %, ASPmax = 100 % then 16384 represents 300 %.
This parameter will vary from 5461 to 16384.
Case b:
ASPmin = -200 %, ASPmax = 100 % then 16384 represents 200 %.
This parameter will vary from -16384 to +8192.

See r0752
Note:
This value is used as an input to analog BICO connectors. ASPmax represents the highest analog set-
point (this may be at 10 V). ASPmin represents the lowest analog setpoint (this may be at 0 V). See
P0757 to P0760 (analog input scaling).
P0756[0...1]
Type of analog input
0 - 4
0
T
-
-
U16
2
Defines type of analog input and also enables analog input monitoring.
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 V to 10 V)
Index:
See r0752
Dependency:
The monitoring function is disabled if the analog scaling block is programmed to output negative setpoints
(see P0757 to P0760).
Notice:
When monitoring is enabled and a deadband defined (P0761), a fault condition will be generated (F80) if
the analog input voltage falls below 50 % of the deadband voltage. It is not possible to select the bipolar
voltage for analog input 2.
For P0756 = 4, you need to ensure the analog input scaling, for example, if you desire to obtain an output
frequency within the range of -50 Hz to 50 Hz, you can set parameters P0757 to P0760 within their nega-
tive ranges (examples: P0757 = -10 V, P0758 = -100%).
Note:
See P0757 to P0760 (analog input scaling).
In current mode, if the input exceeds 24mA, the converter will trip F80/11 for analog input 1 and F80/12 for
analog input 2. This will result in channel switching back to voltage mode. Analog input parameter read-
ings for the channel concerned will no longer be updated until the fault (F80) has been reset. Once the
fault has been reset then the input will switch back to current mode and normal readings will resume.
