126 Functional Description CG Drives & Automation, 01-5326-01r5
F(Value), Process Min [327]
This function is used for scaling if no sensor is used. It offers
you the possibility of increasing the process accuracy by
scaling the process values. The process values are scaled by
linking them to known data in the AC drive. With
“F(Value) Proc Min [327]” the precise value at which the
entered “Process Min [324]“is valid can be entered.
Communication information
F(Value), Process Max [328]
This function is used for scaling if no sensor is used. It offers
you the possibility of increasing the process accuracy by
scaling the process values. The process values are scaled by
linking them to known data in the AC drive. With F(Value),
Proc Max the precise value at which the entered “Process
Max [525]” is valid can be entered.
Communication information
Example
A conveyor belt is used to transport bottles. The required
bottle speed needs to be within 10 to 100 bottles/s. Process
characteristics:
10 bottles/s = 150 rpm
100 bottles/s = 1500 rpm
The amount of bottles is linearly related to the speed of the
conveyor belt.
Set-up:
“Process Min [324]” = 10
“Process Max [325]” = 100
“Ratio [326]” = linear
“F(Value), ProcMin [327]” = 150
“F(Value), ProcMax [328]” = 1500
With this set-up, the process data is scaled and linked to
known values which results in an accurate control.
