8.2 Parameter list
Parameter Function
Index: See r0752
Note: This value is used as an input to analog BICO connectors. ASPmax represents the highest analog setpoint
(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
Defines type of analog input and also enables analog input monitoring.

4
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 inverter 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 readings
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.
P0757[0...1] Value x1 of analog input
scaling
P0757 - P0760 configure the input scaling. x1 is the first value of the two pairs of variants x1 / y1 and x2 /
y2 which determine the straight line. The value x2 of analog input scaling P0759 must be greater than the
value x1 of analog input scaling P0757.
Index: See r0752
Notice:
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 10 V or 20 mA).
•
ASPmin represents lowest analog setpoint (this may be at 0 V or 20 mA).
•
Default values provide a scaling of 0 V or 0 mA = 0 %, and 10 V or 20 mA = 100 %.
•
P0758[0...1] Value y1 of analog input
scaling [%]
Sets value of y1 as described in P0757 (analog input scaling)
Index: See r0752
Dependency: Affects P2000 to P2003 (reference frequency, voltage, current or torque) depending on which setpoint is to
be generated.
