Ratio [326]
This menu is not visible when speed, frequency or torque is
selected. The function sets the ratio between the actual
process value and the motor speed so that it has an accurate
process value when no feedback signal is used. See Fig. 80.
Communication information
Fig. 80 Ratio
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.
Default: Linear
Linear 0 Process is linear related to speed/torque
Quadratic 1
Process is quadratic related to speed/
torque
