3.6.1 Influence ofHarmonics
1) The high frequency harmonics of mains supply will influence the rectifying circuit of the
inverter. The harmonics will heat the rectifying circuit and even damage the circuit. So, it is
recommended to install the filtering device in the environmentwhere the power quality is poor.
2）Since the inverter output has high frequency harmonics, the output cannot be installedwith
capacitor or surge suppressing devices because the capacitor and surge suppressing device may
resonate the circuit and damage the equipment.
3.6.2 EMI
1) Two kinds of EMI, one is the EMI around the inverter and disturbs the inverter. This kind of
EMI is weak, besides the inverter has been designed with strong immunity.Another is the EMI
from the inverter that may influence the equipment around the inverter. The inverter itself is a
disturbance source because it outputs PWM wave through high carrier frequency, so solving the
Otherwise, when the digital output terminal has output, the DC 24V power supply and output
circuit will be damaged immediately.

Delay output terminal RA/B/C、TA/B/C wiring
（5）
If driving an inductive load(such as the electromagnetic relay,the contactor), surgevoltage
absorption circuit should be installed, such as RC absorption circuit(Pay attention that its leaking
current should be less than keeper current of the contactor or relay controlled by it),
voltage-sensible resistance, and diode,etc.(If it is used in DC electromagnetic loop, check the
polarity when install). Component of absorption circuit should be installed on the two side of the
coil of delay or contactor.
3.6 EMC Issues
- 30-
Page 36
ACD320user manual Installation and wiring
EMI issue is mainly toreduce the EMI of inverter.
Methods:
A) Inverter and other equipment shall be well grounded and the grounding resistance shall be
less than 5ohm.
B) Inverter's power cables shall be vertical instead of parallel with the control cables.
C) For the applicationwith strong disturbance, the power cables from the motor to the inverter
shall be shielded and the shielding layer shall be grounded.
D) The cables of disturbed equipment shall be twisted shielded cables and the shielding layer
shall be grounded.
2) Reducing the disturbance to the inverter from other equipment
The relay, contactor or electronic -magnetic braking device will disturb the inverter.
Take the following actions to solve this issue:
A) Install surge suppressing devices to the disturbing device
B) Install filter to the input of the inverter
C) Inverter's control cables shall be shielded and the shielding layer shall be grounded
3)Method to reduce the disturbance fromthe inverter to the equipment
Two kinds of noises, one is the radiation from the inverter itself, and another is the radiation from
the cable between the inverter and the motor. These two kinds of radiations induce the cables of
the equipment and make the equipment work abnormally. Following method can be used:
A) If themeasuring meters, radio equipment and sensors and their signal cables are installed in a
cabinet together with the drive, these equipment cableswill be easily disturbed. Take the actions
below to solve the problem: The equipment and the signal cables should be as far away from the
inverter as possible; Signal cables and power cables shall not be routed in parallel or bound
together; The signal and power cables should be shielded; Install radio noise filter and linear
noise filter at the input and output sides of the inverter.
B) If the external equipment shares a sameAC supply with the inverter, and the above cannot
eliminate the disturbance, then the user should install a linear filter or a radio noise filter.
- 31-
Page 37
ACD320user manual Installation and wiring
C) Ground the external equipment and eliminate the disturbance of the leakage current fromthe
inverter's grounding cable.
3.6.3 Leakage current
The inverter has two kinds of leakage current, one is the grounding leakage current and another
is the leakage current between the lines:
1) Grounding leakage current:
The distributed capaci tance exists between the cables and the ground, and the bigger the
capacitance and the bigger the leakage current, so themotor cables should be as short as possible.
Besides, the bigger the carrier frequency is, the bigger the leakage current is, so the user can also
reduce the carrier wave frequency, but themotor noise may increase. Installing reactor can also
reduce the leakage current.
The leakage current is increasedwith the increase of the circuit current, so the leakage current is
big if the motor power is big.
2) Leakage current between lines:
The distributed capacitance exists in the inverter output cables, andresonancemayoccurifhigh
frequency harmonics exist in the current, thus the leakage current occurs, which may result in the
wrong action of relay.
The method to solve this issue is to reduce the carrier frequency or install the output reactor. It is
recommended to use inverter protection function instead of a thermal relay to protect themotor
before using the inverter.

Example: Change the setting of F1.02 from 10.00Hz to 15.00Hz. (Bold means flash bit.)
Fig. 4-3 Example for Parameter Changing
In third level menu, if the parameter has no flash bit, it means the function code cannot be
changed and the possible reasons are:
1) This parameter of this function code cannot be changed, such as the actually detected
parameter and running record parameter.
2) This function code cannot be changed in operating status and can only be changed when
the inverter is stopped.
4.3 How to View Status Parameters
When ACDSeries inverter is in the stop or running status, several status parameter of the
inverter can be displayed on the LED nixie tube. The status can be chosen wether to display by
function code F3.05(running parameter)、F3.06 (stop parameter), please refer to the discrption of
F3.05 and F3.06 for detail. Pressing the key SHIFT can switch the display of stop or running
status parameters by moving to the right circularly, and pressing the key ENTER +M can switch
the display of stop or running status parameters by moving to the left circularly.
There are nine stop status parameters to be displayed in the stop status, Setting frequency,
DC bus voltage, Input terminal status,Output terminal status,PID setpoint,PID feedback, AVI
value, ACI value, segment of multi-speed , the function code F3.06 can decide these parameters
wether to display by bit. Pressing the key SHIFT can switch the display of the selected
parameters by moving to the right circularly, and pressing the key ENTER +M can switch the
display of the selected parameters by moving to the left circularly.
The inverter has fifteen running status parameters to be displayed in the running status, they
are running frequency, setting frequency, Output current,Output voltage, Running speed, Output

power, Output torque, DC bus voltage, PID setpoint, PID feedback, Input terminal status, Output
terminal status, AVI value, ACI value, current segment of multi-speed, setting torque, the
function code F3.05 can decide these parameters wether to display by bit. Pressing the key
SHIFT can switch the display of the selected parameters regularly.
If the inverter is powered on again after power-off, the parameters displayed are defaulted as
those selected before the power-off.
4.4 Password Setting
ACD320 inverter provides password protection for users. When F3.00 is not zero, that is
the user password, once exiting the function code editing status, the password protection function
is valid if there is no operation within one minute. If the userpresses PRG/ESC again, the inverter
shall display “0.0.0.0.0.”, and the user can only enter the menu after inputting the user password.
Otherwise, the user cannot enter.If the user wants to cancel the password protection function,
F3.00 should be set 0.
4.5 Auto Tuning of Motor Parameters(Referto F1.11)
Before running the inverter that has selected the vector control mode or open loop torque mode,
accurate motor nameplate parameters must be input to the inverter correctly. ACD320 inverter
will configure the standard motor parameters according to the nameplate parameters. Vector
control mode is highly dependent on the motor parameters and correct parameters must be
acquired for achieving good control performance.
Motor auto tuning procedures:
Firstly set the command source (F0.01) as the operation panel command channel.
Then input the following parameters according to the actual parameters of motor:
F1.01 Rated power of motor
F1.02 Rated frequency of motor
F1.03 Rated speed of motor
F1.04 Rated voltage of motor
F1.05 Rated current of motor
If the motor is disconnected from the load completely, select 1 (complete tuning) in F1.11, and
press RUN in keypad, the inverter will calculate the parameters below automatically:
F1.06 Stator resistance
F1.07 Rotor resistance
F1.08 Leakage inductance
F1.09 Mutual inductance
F1.10 Excitation current with no load

m
Where I0is the excitation current with no load, Lmis the mutual inductance and Lδis the leakage
inductance.
If the motor cannot disconnect from its load, set F1-11 to 2 (static tuning), and then press the
RUN. The inverter will measure the stator resistance, rotor resistance and leakage inductance in
sequence, but it will not calculate the mutual inductance and the excitation current with no load,
and the user can use the nameplate parameters that are rated voltage U, rated current I, rated
frequency f and power factor η to calculate these two parameters.
The calculation methods of the motor current with no load and the mutual inductance are
described as follows:

This function is mainly used to improve the motor operating noise and inverter interference
to external. The advantages of using high carrier frequency: relatively ideal current wave shape,
less harmonic current wave and low motor noise;
The disadvantages of using high carrier frequency: increased switch loss and inverter
temperature rises, affecting inverter output capacity so that it should be operated at derating
under high carrier frequency conditions; in the mean time, inverter leakage current and its
electromagnetic interference to external are increased.
The situations of using low carrier frequency is on the contrary. Too low carrier frequency
can cause operation unstable, torque reduced and even oscillation at low frequency.
When inverter is factory released, its carrier frequency has been set properly. Generally the
user does not need to modify this parameter.

Note: please set these codes according to motor nameplate parameters. The superior
performances of vector control require precise motor parameters.
ACD series inverter provides parameter self-learning function. Accurate parameter
self-learning comes from correct setting of motor nameplate parameters.
In order to ensure the control performances, please do the motor setting based on the
inverter standard adaptive motor. If the motor rated power has a too big difference to the
standard adaptive motor, the inverter control performances will be deteriorated distinctly.
Note: resetting of motor rated power (F1.01) can initialize motor parameter F1.02-F1.10.

By means of setting the proportion factor and integration time of the speed regulator, the
speed dynamic response of vector control can be regulated. Increasing the proportional gain,and
reducing the integration time, can equally quicken the dynamic response of speed loop,but either
the proportional gain being too much or the integration time being too short can easily cause
system oscillation and too big overshoot. The proportional gain being too small also can lead to
system steady state oscillation and possibility of speed steady-state error occurring.
Speed loop PI parameters have an intimate relationwith the inertia ofmotor system, and
therefore based on the default PI parameter the user needs to make adjustment for different
loading character in order to meet different requirement.

Torque Boost is mainly applied to less than cut-off frequency (F1.22). TheV/F curve after
boost is shown in following figure. Torque booth can improve the low frequency torque
performance ofV/F control.
Based on the load, a torque should be chosen properly. For heavy load, increase the torque
boost, but the torque boost should not be set too big, whichwill result in the motor operating at
overexcitation and that it could be overheated, and also the inverter output current is big,
reducing efficiency.
When the torque boost is set as 0.0%, the inverter is at automatic torque boost.

Proportional gain (Kp): determines the adjusting strength of PIDadjustor. The bigger the P,
the bigger the adjusting strength is. This parameter being 100 means that when the difference
between the PID feedback value and the assigned value is 100%, the adjusting range of PID
adjustor to the output frequency command is the maximum frequency (ignore integral action and
derivative action).
Integrating time (Ti): determines the speed at which PIDadjustor performs integral
regulation to the discrepancy between the PID feedback value and the assigned value. The Ti is
indicating the period of time that integral controller (ignore proportional action and derivative
action), when the discrepancy between the PID feedback value and the assigned value is 100%,
continuously regulates to make the regulating amount to reach the maximumfrequency (F0.047).
The shorter the integrating time, the stronger the adjusting strength is.
Differential time (Td): determines the controlling strength at which PID adjustor performs

adjustment to the variance ratio of discrepancy between the PIDfeedback value and the assigned
value. TheTd is indicating the period of time within which if the feedback value is changed
100%, the regulating amount of integral controller is the maximum frequency (F0.04) (ignore
proportional action and integral action). The longer the Td, the bigger the controlling strength
is.PID is the most popularly used controlmode in process control, with each part playing different
role. Following simply introduces the operational principle and the controlling method:
Proportion control (P): when there is discrepancy between feedback and the
assignment,output the regulating amount in proportion to the discrepancy. If the discrepancy is
constant,the regulating amount keeps constant. Proportion control can response quickly to the
feedback variation, but only using proportion control is unable to perform noncorresponding
control. The bigger the proportional gain, the faster the system regulating speed, but being too
bigmay cause oscillation. The control method is first to set a long integrating time and a zero
differential time, and then run the system only by using proportion control. Change the assigned
value, and watch the stable discrepancy (steady-state error) of feedback signal and assigned value.
If the steady-state error is at the varying direction of assigned value (for instance, increase the
assigned value, the feedback value after the system is steady is always less than the assigned
value), continue to increase the proportional gain, otherwise decrease it.Repeat the above until
the steady-state error is relatively small (it is very difficult to do no steady-state error).
Integral time (I): when there is a discrepancy between the feedback and
assignment,continuously accumulate the output regulation amount. If the discrepancy still exists,
continue to increase the regulation amount until there is no discrepancy. Integral controller can
effectively eliminate the steady-state error. Integral controller being too strong can cause
repeated overshooting, systemunstable and up till oscillating. The characteristic of oscillation
caused by too strong integral action is that the feedback signal is swinging up and down around
the assigned value, and the amplitude of swing increases gradually till the oscillation happens.
Normally the integral time is adjusted from big to small, gradually regulate the integral time, and
watch the effect, until the systemstable speed meets requirements.
Differential time (D): when the discrepancy between feedback and assignment varies,output
a regulation amount in proportion to the variance ratio of discrepancy. The regulation amount is
related to the direction and magnitude of discrepancy variation, but irrelevant to the direction and
value of the discrepancy itself. The differential control action is to perform the control according
to the varying trendwhen the feedback signal variation happens, and thereby to restrain the
feedback signal variation. It should be caution to use differential controller as the differential
control have a trend to magnify the system interference, especially the high varying frequency

During the inverter deceleration, the load inertia may cause the actualmotor speed drop rate
lower than the output frequency drop rate, and thereby the motor generates electricity and feeds it
back to the inverter, causing the inverter bus voltage going up and even bus over-voltage
breakdown which then can cause inverter tripping if no provision ismade.
Over-voltage stall protection function is to detect the bus voltage and compare itwith the
stall over-voltage point defined by F5.05 (relative to the standard bus voltage). If it exceeds the
over-voltage stall point, inverter output frequency stop going down, and when the next bus
voltage detected is lower than the over-voltage stall point, the inverter continues to decelerate,as

When inverter is running, the actual climbing rate of motor speed is lower than climbing
