5.14 FD Group Multi-step Speed and Simple PLC Parameters
Simple PLC function is a programmable logic controller (PLC) in the AC drive,
which can automatically control the logic of multi-step frequency. In order to meet
the technical requirements, it can conduct running time, running direction and
running frequency. VFD can realize 16-stage speed variation control and there are
four kinds of acceleration and deceleration time for selection. When PLC
completes one cycle, ON signal can be output by multi-function digital output
terminal MO1 or multi-function relay 1. For details, see F1.02 ~ F1.05. When the
frequency reference selection is multi-speed operation mode (Parameters F0.07,
F0.03 and F0.04), it is needed to set FD.00 for required characteristic.
