】
F04.10 defines the maximum deviation of the
output from the process PID reference.
• PID regulator stops operation when the
feedback value is within this range.
• Setting this parameter correctly is
instructive to improve the system output
accuracy and stability.
F04.11
PID regulator upper limit source selection
0

2
【
0
】
0: Set by F04.13.
1: Set by analogue value. Set by analogue input voltage, refer to Group F16.
2: Set by terminal pulse input.
F04.12
PID regulator lower limit source selection
0

【
0
】
It defines the setting source of PID regulator lower limit value.
0: Set by F04.14.
1: Set by analogue value. Set by analogue input voltage, refer to Group F16.
2: Set by terminal pulse.
F04.13
PID regulator upper limit value
0.00
－
upper limit
【
50.00Hz
】
It defines that the process PID regulator output digital setting value of upper limit.
F04.14
PID regulator lower limit value
0.00
－
upper limit
【
0.00Hz
】
It defines that the process PID regulator output digital setting value of lower limit.
F04.15
PID regulator characteristic
0,1
【
0
】
0: Positive. The motor speed is required to increase with the increase of the reference.
1: Negative. The motor speed is required to decrease with the increase of the reference.
F04.16
Integral regulation selection
0,1
【
1
】
0: Stop integral regulation when the frequency reaches the upper or lower limit.
1: Continue the integral regulation when the frequency reaches the upper or lower limit.
• It is recommended to disable the integral regulation when the frequency reaches the upper or
lower limit on condition that fast response is needed.
F04.17
PID output filter time
0.01
－
10.00
【
0.05s
】
It defines the filtering time of process PID output.
F04.18
PID output reverse selection
0,1
【
0
】
0: PID regulation disable reverse. When PID output is negative, 0 is the limit.
1: PID regulation enable reverse. When F00.18 = 1 (disable reverse), 0 is the limit.
F04.19
PID output reverse frequency’s upper limit
0.00
－
upper limit
【
50.00Hz
】
It defines the PID upper limit frequency when reverse. When F04.18 = 1 (PID regulation enable
reverse), it is enabled.
