5.5.13 Simple PLC
Simple PLC is a multi-step speed generator, and the inverter 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 inverter itself can achieve this function.
DRV-28 series inverter can realize 16-step speeds control, and provide four groups of
acceleration/deceleration time for users to choose from.
After the set PLC completes one cycle (or one section), one ON signal can be output by the
multi-function relay.
