8、Communication setting
The output voltage is set by the host computer by means of communication.
The voltage source for V/F separation is set in the same way as
the frequency source. For details, see P0.01. 100.0% of the
setting in each mode corresponds to the rated motor voltage. If
the corresponding value is negative, its absolute value is used.
P5.14 Voltage digital setting
for V/F separation
Setting Range：
0V to rated motor voltage
0
When P5.13 set to 0, the output voltage is set by P5.14.
P5.15 Voltage rise time of V/F
separation
Setting Range：
0.0S~1000.0S
0
P5.15 indicates the time required for the output voltage to rise from 0 V to the rated motor
voltage.
6.7 PID Function（Group P6）
PID control is a general process control method. By performing proportional, integral and
differential operations on the difference between the feedback signal and the target signal, it
adjusts the output frequency and constitutes a feedback system to stabilize the controlled
counter around the target value.
It is applied to process control such as flow control, pressure control and temperature
control. The following figure shows the principle block diagram of PID control.
