5.5.13 Simple PLC
Simple PLC is a multi-step speed generator, and the VFD can change the running frequency and
direction automatically based on the running time to fulfill process requirements. Previously, such
function was realized with external PLC, while now, the VFD itself can achieve this function.
The VFD can realize 16-step speeds control, and provide four groups of acceleration/deceleration
time for choose.
After the set PLC completes one cycle (or one step), one ON signal can be output by the multifunction
relay.
