5: Pulse reference
The frequency is set by the DI pulse
frequency. The frequency is
calculated according to the
corresponding relationship curve
between the pulse frequency and
the frequency.
6: Multi‑reference
When the parameter is set to 6,
combinations of different DI states
correspond to different frequency
references. The four multi‑reference
terminals can provide 16 states,
corresponding to 16 reference
values.
7: Simple PLC
Simple PLC is a multi‑reference used
to control the running time and
acceleration/deceleration time.
Multi‑reference parameters are used
to set the values of each frequency.
The simple PLC module is used to
set the running time and
acceleration/deceleration time of
each frequency. Up to 16 speeds can
be set.
8: PID
PID is selected as the frequency
source. As a general process control
method, PID control is a closed‑loop
mechanism in which each controlled
variable is stabilized at the target
level. This is implemented through
proportional, integral, and
differential calculation of the
difference between the feedback
signal and the target signal of the
controlled variable and through
adjustment of the AC drive output
frequency. PID control is generally
used in closed‑loop control
scenarios, such as constant pressure
closed‑loop control and constant
tension closed‑loop control.
