This function allows a configurable Speed ratio to be applied to the main reference Speed ref 1.
The Speed ratio range can be set between 0 and 32767 if written in digital form. It can be set from 0 to 20000
(0 to +10V) if assigned via an analog input.
This function is useful in a multidrive system where between the motors is required (see example in figure
6.14.5.2).
The speed resulting value can be read through the Spd draw out parameter via an analog output.
Speed ratio This parameter determines the speed ratio value.This setting can be done in digital form,
via LAN or through an analog input.
Spd draw out (d) Speed value in the unit specified by the factor function.
Spd draw out (%) Speed value as a percentage of Speed base value.
