F5.16 Close-loop regulation
characteristic
Range:0. 1【0】
0: Positive
Set F5.16 to 0 if the motor speed is required to be
increased with the increase of the reference.
1: Negative
Set F5.16 to 1 if the motor speed is required to decrease
with the increase of the reference.
F5.17 Integral regulation selection
Range:0. 1【0】
0: Stop integral regulation when the frequency reaches
the upper and lower limits
1: Continue the integral regulation when the frequency
reaches the upper and lower limits
It is recommended to disable the integral regulation for
the system that requires fast response.
F5.18 Preset close-loop
frequency
Range:0.00~650.00Hz
【0.00Hz】
F5.19 Holding time of
preset close-loop frequency
Range:0.0~3600s【0.00s】
This function can make the close-loop regulation enter
stable status quickly.
When the close-loop function is enabled, the frequency
will ramp up to the preset close-loop frequency (F5.18)
within the Acc time, and then the drive will start
close-loop operation after operating at the preset
frequency for certain time(defined by F5.19).

Note:
You can disable the function by set both F5.18 and F5.19 to
0.
F5.20 Preset close-loop

Range:0.0~10.00V【0.00V】
F5.21 Preset close-loop
reference 2
Range:0.0~10.00V【0.00V】
F5.22 Preset close-loop
reference 3
Range:0.0~10.00V【0.00V】
F5.23 Preset close-loop
reference 4
Range:0.0~10.00V【0.00V】
F5.24 Preset close-loop
reference 5
Range:0.0~10.00V【0.00V】
F5.25 Preset close-loop
reference 6
Range:0.0~10.00V【0.00V】
F5.26 Preset close-loop
reference 7
Range:0.0~10.00V【0.00V】
Among the close-loop reference selectors, besides the 3
selectors defined by F5.01, the voltage value defined by
F5.20~F5.26 can also be used as the close-loop
reference.
Voltage of preset close-loop reference 1~7 can be
selected by terminals, refer to introductions to
F7.00~F7.07 for details. These functions can also be
used in conjunction with PLC operating functions, see
introductions to group F4 parameters for details.
The priority preset close-loop reference control is higher
than the reference selectors defined by F5.01.
5.7 Traverse Operating Parameters (Group F6)
Traverse operation is widely used in textile and chemical fiber industry. The typical application is shown in Fig. 5-37.
Traverse operation process: First, the drive accelerates to the preset frequency of traverse operation (F6.02) within the
Acc time and then waits for certain time (F6.03). The drive transits to the central frequency within Acc/Dec time, and at
last the drive traverse according to the preset traverse amplitude (F6.04), jitter frequency(F6.05), traverse cycle(F6.06)
and rising time of traverse operation (F6.07) until it receives a stopping command and stops within Dec time.
