Simple PLC function is also a multi-step speed generator. The VFD can change the running frequency, direction to meet the need of processing according to the running time automatically. In the past, this function needs to be assisted by external PLC, but now the VFD can realize this function by itself.
The series VFDs can control 16-stage speed with 4 groups of ACC/DEC time.
The multi-function digital output terminals or multi-function relay output an ON signal when the set PLC finishes a circle (or a stage).
