Smooth time analog
P0753[0...1]
input [ms]
Defines filter time (PT1 filter) for analog input.
See r0752
Index:
Increasing this time (smooth) reduces jitter but slows down response to the analog input.
Note:
P0753 = 0: No filtering
Actual analog input value
r0754[0...1]
after scaling [%]
Shows smoothed value of analog input after scaling block.
See r0752

P0757 to P0760 define range (analog input scaling).
Dependency:
CO: Actual analog input
r0755[0...1]
after scaling [4000h]
Displays analog input, scaled using ASPmin and ASPmax (ASP = analog setpoint).
Analog setpoint (ASP) from the analog scaling block can vary from minimum analog setpoint (ASPmin) to
a maximum analog setpoint (ASPmax).
The largest magnitude (value without sign) of ASPmin and ASPmax defines the scaling of 16384.
By associating r0755 with an internal value (e.g. frequency setpoint), a scaled value is calculated internal-
ly by the inverter.
The frequency value is calculated using the following equation:
r0755 [Hz] = (r0755 [hex] / 4000 [hex]) * P2000 * (max (|ASP_max|, |ASP_min|) / 100%)
Case a:
Example:
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.

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).
Type of analog input
P0756[0...1]
