7: Simple PLC
When the simple programmable logic controller (PLC) mode is used as the frequency
source, the running frequency of the AC drive can be switched over among the 16
frequency references. You can set the holding time and acceleration/deceleration time

8: PID
The output of PID control is used as the running frequency. PID control is generally
used in on-site closed-loop control, such as constant pressure closed-loop control and
constant tension closed-loop control.
When applying PID as the frequency source, you need to set parameters of PID

9: Communication setting
The frequency is set by means of communication.
If the AC drive is a slave in point-point communication and receives data as the
