It defines the max. deviation of the output from the
reference, as shown in Fig. 5-35. PI regulator stops
operation when the feedback value is within this range.
Setting this parameter correctly is helpful to improve the
system output accuracy and stability.

Set F5.16 to 0 if the motor speed is required to be
increased with the increase of the reference.

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

It is recommended to disable the integral regulation for
the system that requires fast response.

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).

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
Chapter 5 Parameter Introductions 59

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.

The central frequency is actually the preset frequency of simple operation (except PLC, traverse operation, jog),
multi-step speed operation or PLC operations;
Traverse operating function is disabled automatically in Jog operation or close-loop operation process.
If PLC operation and traverse operation start at the same time, the traverse operation is disabled when the drive transits
from one PLC operating stage to another stage. The drive will accelerate to the preset frequency of PLC operation and
then start traverse operation. The drive will decelerate to stop within the Dec time set in PLC operating stage.
