User Manual of A90 Series Inverter conveyor belts. In the acceleration process shown in Fig. 7-15, t1 is the set value of F04.15, and t2 is the set value of F04.16. In the deceleration process, t3 is the set value of F04.17, and t4 is the set value of F04.18. The slope of the output frequency remains unchanged between t1 and t2 as well as between t3 and t4. F04.14=2: intermittent S-curve acceleration and deceleration Compared with the continuous S-curve, the intermittent S-curve will not be over-tuned. The current S-curve trend will be stopped immediately according to changes in the settings and acceleration/deceleration time, and the new planned S-curve trend will be applied.

The motor decelerates to stop according to the set deceleration time [default setting: F04.19=1: free stop When the stop command is valid, the inverter will stop output immediately, and the motor will freely coast to stop. The stop time depends on the inertia of the motor and load. 165 Function Default Function code name Parameter description Unit Attribute code setting F04.19 Stop mode 0: Slow down to stop 1: Free stop 0 ○
