r0752[0...1] Actual analog input [V] or
[mA]
- - - - - Float 2
Displays smoothed analog input value in volts or million amps before the scaling block.
Index: [0] Analog input 1 (AI1)
[1] Analog input 2 (AI2)
P0753[0...1] Smooth time analog
input [ms]
0 - 10000 3 U, T - - U16 3
Defines filter time (PT1 filter) for analog input.
Index: See r0752
Note: Increasing this time (smooth) reduces jitter but slows down response to the analog input.
P0753 = 0: No filtering
r0754[0...1] Actual analog input value
after scaling [%]
- - - - - Float 2
Shows smoothed value of analog input after scaling block.
Index: See r0752
Dependency: P0757 to P0760 define range (analog input scaling).
r0755[0...1] CO: Actual analog input
after scaling [4000h]
- - - - 4000H I16 2
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 internally
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%)
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.
