Controller optimization guiding transmission behavior
Controller optimization guiding behavior
Specify travel parameters (20% of the final speed)
and activate movement cycle
Evaluation of the signals with the aid of the software
oscilloscope :
Recommendation(signals):
1.) Setpoint speed of setpoint generator (Obj. 681.4)
2.) Actual speed filtered (Obj. 681.9)
3.) Target current r.m.s.( torque-producing ) (Obj. 688.18)
4.) Following error (Obj. 680.6)
Control result OK?
(Following error...)
Current threshold?
Reduce acceleration/deceleration or
increase current threshold.
Optimization with the feedforward
parameters:
1.) Acceleration feed-forward
2.) Current feed-forward
3.) Jerk feed-forward
yes
no
no
Increase setpoint speed by 10%-20%
Final speed reached?
