1.P re fa c e
Dangerous and wrong use may cause casualties
Danger
●The power supply must be turned off when laying the wires.
●When the AC power supply is cut off but the indicator light of the mani-
pulator of AC drive is still on, there is still high voltage in the AC
drive which is very dangerous, please do not touch the interior circuit and
components.
●Do not check the components and signals on the circuit board during
operation.
●The terminal of AC drive must be grounded correctly.
●Do not refit or replace the control board and parts without permission,
otherwise, there are risks such as electric shock and explosion.
！Wrong use may cause damage to AC drive or mechanical system
！Notice
●Please do not test the voltage resistance of the interior components of AC
drive, as the semiconductor of AC drive is easy to be punctured and damaged
by high voltage.
●Never connect the main circuit output terminals U, V, and W directly to
the AC main circuit
power supply.
●The circuit board of the AC drive has CMOS IC which is extremely easy to
be damaged by static electricity, thus please do not touch the circuit board
with your hand before taking anti-static electricity measures.
●Only the qualified motor professionals can install the driver, lay the wire,
repair and maintain the AC drive.
●The scrapping of AC drive shall be treated as industrial waste and burning
is strictly prohibited.

It is only valid for vector control and
invalid for VF control. Running at diff-
erent frequencies, different PI parameters
of speed loop can be selected. When the
operating frequency is less than the
switching frequency 1, the PI adjustment
parameters of the speed loop are P2-01 and
P2-02. When the operating frequency is
greater than the switching frequency 2,
the PI adjustment parameters of the speed
loop are P2-04 and P2-05. The PI parameters
of speed loop between switching frequency
1 and switching frequency 2 are linear
switching of two groups of PI parameters.
By setting the proportional coefficient
and integral time of the speed regulator,
the dynamic response characteristics of
the vector control can be adjusted. The
dynamic response of the speed loop can be
accelerated by increasing the proportional
gain and reducing the integration time.
However, if the proportional gain is too
large or the integration time is too small,
the system may oscillate.

For the speed sensorless vector control,
this parameter is used to adjust the speed

speed of the motor is low when it is loaded,
this parameter will be increased, and vice

The current loop PI parameter of vector
control can be obtained automatically after
the asynchronous machine is fully tuned or
the synchronous machine is no-load tuned,
which generally does not need to be modified.
If the current loop PI gain setting is too
large, the whole control loop may oscillate.
Therefore, when the current oscillation or
torque fluctuation is large, the PI propor-
tional gain or integral gain can be reduced
manually.

11: In VF semi separation mode, V and F are
proportional, but the proportional relation-
ship can be set through voltage source P3-15,
and the relationship between V and F is also
related to the rated voltage and rated
frequency of P1 group motor.
0.1～30.0%
In order to compensate the low-frequency
torque characteristics of V / F control,
the output voltage of the AC drive at low-
frequency is increased and compensated. But
the torque lifting setting is too large,
the motor is easy to overheat, and the AC
drive is easy to overcurrent. When the
torque rise is set to 0.0, the AC drive is
the automatic torque rise. At this time,
the AC drive automatically calculates the
required torque rise value according to the
motor stator resistance and other parameters.
0.00～maximum frequency
Torque lifting torque cut-off frequency:
under this frequency, the torque lifting
torque is effective. If the set frequency
is exceeded, the torque lifting fails.

This parameter is only valid for asynch-

The selection method of the gain is to
minimize the vibration under the premise
of effective suppression, so as to avoid
adverse impact on VF operation. When the
motor has no oscillation, please select the
gain as 0.
Only when the motor oscillates obviously, it
is necessary to increase the gain properly.
The larger the gain is, the more obvious the
suppression of the oscillation is. When using
the vibration suppression function, the motor
rated current and no-load current parameters
shall be accurate, otherwise the VF vibration
suppression effect is not good.

When the frequency converter operates with
load, in order to make the output frequency of
the AC drive avoid the resonance frequency point
of the mechanical load, the jump frequency can
be used to avoid the resonance point. The AC
drivecan set one jumping point to perform
jumping. After setting the jumping frequency
parameter, even if the given frequency of the
AC drive is within the resonance frequency
point of the mechanical load, the output
frequency of the AC drive will be automatically
adjusted outside the resonance frequency point
of the mechanical load to avoid running on the
resonance point.

Timer set value
0～65000
This parameter is used to set the timing
time of the AC drive. The start-up of the
timer is completed by the external timer
trigger terminal of the timer. The timing
starts from the reception to the external
trigger signal. After the timing time
arrives, the corresponding output terminal
outputs a pulse signal with a width of 1
second. If the external trigger signal is
always in the trigger state, the corres-
ponding output terminal will output a pulse
signal every [P8-28] set time. When the
trigger terminal is invalid, the timer keeps
the existing timing value, and continues to
accumulate the timing after the trigger
terminal is valid. The timer clearing
terminal can clear the timing value at any
time.

When the counter reaches the value speci-

when the next counting signal is input, the
output terminal stops outputting the effec-
tive signal.

This function is used to give a warning
signal to the control system through y
before the motor overload fault protection.
The early warning coefficient is used to
determine the degree of early warning before
motor overload protection. The larger the
value is, the smaller the alert advance is.

warning coefficient
This function refers to that when the power
is cut off or the voltage is suddenly reduced,
the AC drive will reduce the output speed and
compensate the load feedback energy to reduce
the DC bus voltage of the AC drive, so as to
maintain the continuous operation of the AC
drive. If P9-01 BIT1=1, the AC drive will
slow down when the power is cut off or the
voltage drops suddenly. When the bus voltage

returns to normal, the AC drive will acce-
lerate to the set frequency. The basis for
judging whether the bus voltage returns to
normal is that the bus voltage is normal and
the duration exceeds the F9-61 setting time.
If P9-01 is BIT1=2, when the power is cut
off or the voltage is suddenly reduced, the
AC drive will slow down until it stops.

If the load shedding protection function is
effective, when the output current of the
AC drive is less than the load shedding
detection level P9-38 and the duration is
greater than the load shedding detection
time P9-39, the output frequency of the AC
drive will automatically reduce to 7% of
the rated frequency. During the off load
protection period, if the load is recovered,
the AC drive will automatically return to
operate at the set frequency.

In the process of converter deceleration,
when the DC bus voltage exceeds the over-
voltage stall protection voltage, the AC
drive stops deceleration and maintains the
current operation frequency, and continues
deceleration after the bus voltage drops.
Overvoltage stall gain is used to adjust
the AC drive's ability to suppress over-
voltage during deceleration. The larger
the value is, the stronger the ability of
restraining overvoltage is. Without over-
voltage, the smaller the gain setting is,
the better.

When the output current of the AC drive
reaches the set overcurrent stall protection
current P9-47, the output frequency of the
AC drive will be reduced when the speed is
accelerated; when the speed is constant, the
output frequency will be reduced; when the
speed is reduced, the speed will be slowed
down until the current is less than the
overcurrent stall protection current P9-47,
the operation frequency will return to normal.
