18. REFERENCE VARIATION PERCENT MENU
18.1. Overview
The Reference Variation Percent Menu allows defining the variation values of the speed/torque or PID instant reference
to be entered through digital inputs that have been properly programmed.
As per the selection of the variation percentage programmed to the reference and given by the combination of digital
inputs configured with parameters C175 ÷ C177, please refer to the DIGITAL INPUTS MENU.
The parameters included in this menu represent seven speed/torque or PID variation options to be applied to the speed
reference.
Variation may range from –100.0% to 100.0% of the instant reference given by the addition of all the selected sources.
Example:
P115=
0.0%
Variation percent of reference 1
P116=
50.0%
Variation percent of reference 2
P117=
–80.0%
Variation percent of reference 3
Based on the speed/torque or PID variation selected through digital inputs, the speed reference at constant speed will
be as follows:
Variation 1: the current reference with no changes (no effect).
Variation 2: the current reference increased by 50.0%.
Variation 3: the current reference decreased by 80.0%.
NOTE
Whatever the speed/torque reference value resulting from the application of a speed
variation, the value used to control the motor is saturated at max. a
nd min. speed/torque
values set in the parameters relating to the selected motor.
