Step Logic Using Timed Steps
To activate this function, set Parameter 138 (Speed Reference) to 6
Stp Logic
. Three parameters are used to configure the logic, speed
reference, and time for each step.
•
Logic is defined using Parameters 240…247 (Stp Logic x).
•
Preset Speeds are set with Parameters 170…177 (Preset Freq x).
•
Time of operation for each step is set with Parameters 250…257
(Stp Logic Time x).
The direction of motor rotation can be forward or reverse.
