08.15 defines the feedback limit when the inverter enters the sleep state from the working state. If the actual feedback
value is greater than the set value, and the frequency output by the inverter reaches the lower limit frequency, the inverter
will go to sleep after the delay waiting time defined in 08.17 (i.e. running at zero speed).
08.16 defines the feedback limit of inverter from sleeping state to working state. When PID polarity selects positive
characteristic, if the actual feedback value is less than the set value (or when PID polarity selects negative characteristic, if
the actual feedback value is greater than the set value), the inverter will get out of sleep and start working after the delay
waiting time defined in 08.18.

In case of shutdown during operation (caused by shutdown command, fault or power failure), the inverter not only
automatically records the running time at the current stage but also records the running frequency at the shutdown time,
and then recovers to the running frequency at the shutdown time after starting again, and the remaining phases of the

The above-mentioned function code is used to set the acceleration and deceleration time and running time of
programmable multi-stage speed. The acceleration and deceleration time of 16-segment speed can be set by the
acceleration and deceleration time of 1 ~ 4 segments respectively; The 16-segment running time can be set separately by
the X-segment running time.
16-speed acceleration and deceleration time is set to 0, representing acceleration and deceleration time 1 (00.16 ~
00.17); Set 1, 2 and 3 to represent acceleration and deceleration time 2 (01.13 ~ 01.14), 3 (01.15 ~ 01.16) and 4 (01.17 ~
01.18), respectively.X take 015
Notes:
1: when the running time of a certain stage of 1PLC is set to 0, this stage is invalid.
2: PLC process can be put into operation, suspended, reset, etc. through terminals, please refer to F7 group terminal
function definition.
3. The running direction of 3PLC stage is determined by the frequency plus or minus and the running command. The
actual running direction of the motor can be changed in real time by the external direction command.

mode or when leaving the swing frequency operation mode and the running time at this frequency point. If the function
code 09.61≠0 (swing frequency preset frequency waiting time) is set, the inverter directly enters the swing frequency preset

time.

The Swing amplitude is determined by 09.57, and its reference is determined by 09.57. If 09.57=0,
then the Swing Aw = the maximum output frequency *09.62
If 09.57=1, then swing
AW = given channel frequency *09.62.

Swing frequency control is suitable for textile, chemical fiber and other industries, as well as occasions requiring traverse
and winding functions. Its typical work is shown in Figure F9-6.
Generally, the swing frequency process is as follows: first accelerate to the preset swing frequency (09.60) according to the
acceleration time, wait for a period of time (09.61), then transition to the center frequency according to the acceleration and
deceleration time, and then set the swing frequency amplitude (09.62), sudden jump frequency (09.63), swing frequency
rising time (09.64) and swing frequency falling time.

Tips
1: the center frequency can be given by digital given frequency, analog quantity, pulse, PLC or multi-speed etc.
2: Automatic cancellation of frequency swing during JOG and closed-loop operation.
3: PLC runs with swing frequency. When switching between PLC sections, the swing frequency fails. After transitioning to
the set frequency of PLC according to the acceleration and deceleration setting of PLC stage, the swing frequency starts,
and when stopping the machine, it slows down according to the deceleration time of PLC stage.

This set of functions is used to realize the fixed-length shutdown function.
The inverter inputs counting pulses from the terminal (HDI is defined as function 47), and the calculated length
is obtained according to the number of pulses per revolution of the speed measuring shaft (09.73) and the circumference of
the shaft (09.72).
Calculation length = count pulse number ÷ Number of pulses per revolution × Measure the circumference of shaft
The calculated length is corrected by length magnification (09.70) and length correction coefficient (09.71), and the actual
length is obtained.
108
Actual length = calculated length × Length magnification ÷ Length correction factor
When the actual length (09.69) ≥ the set length (09.68), the inverter will automatically issue a shutdown instruction to stop.
The actual length (09.69) should be cleared or modified before running again < Set the length (09.68), otherwise it will not
start.
Tips
The actual length can be cleared with multi-function input terminal (the input terminal is defined as 46 functions, and
the length count is cleared). If the terminal is valid, the previous length count value will be cleared, and the actual length
can be counted and calculated normally after the terminal is disconnected.
The actual length is 09.69, which is automatically stored when power is cut off.
When the set length 09.68 is 0, the fixed-length shutdown function is invalid, but the length calculation is still valid.
Application example of fixed-length shutdown function:
Spindle
Speed sensor
Speed measuring shaft
Motor
Inverter
Figure F9-7 Example of Long Stop Function
In Figure F9-7, the inverter drives the motor, which drives the spindle shaft to rotate through the conveyor belt, and
the speed measuring shaft contacts the spindle, so that the linear speed of the spindle is detected and transmitted to the
inverter through the counting terminal in the form of pulses. The inverter detects the pulses and calculates the actual length.
When the actual length is greater than or equal to the set length, the inverter automatically stops.

0: prohibited
No motor overload protection (use it with caution).
1: Ordinary motor (electronic thermal relay mode, low-speed compensation)
due to the poor heat dissipation effect of ordinary motor in low-speed operation, the corresponding motor thermal
protection
value should also be adjusted appropriately. The low-speed compensation characteristic
here is to lower the overload protection threshold of motor whose operating frequency is lower than 30Hz.
2. Variable frequency motor (electronic thermal relay mode, low speed without compensation)
Due to the heat dissipation of the frequency conversion special motor is not affected by the rotating speed, there is no
need to adjust the protection value during low-speed operation.

To implement valid overload protection for different types of load motors, it is necessary to set the overload protection
coefficient of motors reasonably and limit the maximum current allowed by the inverter. The motor overload protection
coefficient is the percentage of the rated current value of the motor to the rated output current value of the inverter.
When the inverter drives the motor with matching power level, the motor overload protection coefficient can be set to
100%. As shown in the figure below:

This function code specifies the allowable lower limit voltage of DC bus when the inverter works normally.
Notes:
When the grid voltage is too low, the output torque of the motor will be decreased. For constant power load and
constant torque load, too low grid voltage will increase the input and output current of inverter, thus reducing the reliability
of inverter operation. Therefore, when operating for a long time under low grid voltage, the inverter power needs to be
derated.

In ordinary VF mode, limit amplitude with 10.06 during acceleration and constant speed operation; In vector VF mode,
the amplitude is limited by 10.06 during accelerated operation and infinite amplitude is processed during constant speed

The off load detection time (10.10) defines that the output current of the inverter is less than the load drop detection
level (10.11) for more than a certain time, and then the load drop signal is output.
The off-load status is valid, that is, the working current of the inverter is less than the off-load detection level and the

Notes:
By setting the parameters 10.12 and 10.13, when the output current of the inverter is greater than the overload

utilization rate of the built-in brake unit of the inverter. If the internal DC side voltage of the inverter is higher than the
starting voltage of energy consumption braking, the built-in braking unit will act. If a braking resistor is connected at this
time, the internal pumping voltage energy of the inverter will be released through the braking resistor to reduce the DC
voltage. When the DC side voltage drops to a certain value (starting voltage-brake backlash), the built-in brake unit is
turned off.

When multiple inverters drive the same load, the load distribution is unbalanced due to different speeds, which makes
the inverters with higher speed bear heavier loads. The droop control characteristic is that the speed droop changes with
the increase of load, which can make the load distribution balanced; This parameter adjusts the frequency variation of the
frequency converter with droop speed.

AVR is the automatic voltage regulation function. When there is a deviation between the input voltage and the rated value
of the inverter, this function can keep the output voltage of the inverter constant to prevent the motor from operating in an
overvoltage state. This function is invalid when the output command voltage is greater than the input power supply voltage.
In the deceleration process, if the AVR does not act, the deceleration time is short, but the running current is large; The
AVR acts, the motor decelerates smoothly, the running current is small, but the deceleration time is long.
