The inverter has been strictly and well packed before ex-work. In consideration of various
factors during the transportation special attention should be paid to the following points before
the assembly and installation. If there is anything abnormal please notify the dealer or the
relevant people of our company.
● Check if the inverter has got any damage or deformation during the transportation and handling.
● Check if there is one piece of DLM1series inverter and one user manual when unpacking it.
●Check the information on the nameplate to see if the specifications meet your order (Operating
voltage and KVA value).
● Check if there is something wrong with the innerparts, wiring and circuit board.
● Check if each terminal is tightly locked and if there is any foreign article inside the inverter.
● Check if the operator buttons are all right.
1.2 Before Power-up
！Caution
Check to be sure that the voltage of the main circuit AC power supply matches the input
voltage of the inverter.
E terminals are grounding terminals. Be sure to make correct grounding connection of the
earth terminals of the motor and the inverter for safety.
No contactor should be installed between the power supply and the inverter to be used for
starting or stopping of the inverter. Otherwise it will affect the service life of the inverter.
Danger
●R(L),S,T(N) terminals are power input terminals, never mixed with U.V.W terminals. Be sure
that the wiring of the main circuit is correct. Otherwise it will cause damages of the inverter when
the power is applied to it.
5
！ Caution
Do not carry the front cover of the inverter directly when handling. It should be handled with
the base to prevent the fall-off of the front cover and avoid the dropping of the inverter, which
may possibly cause the injuries to people and the damages to the inverter.
Mount the inverter on a metal or other noncombustible material to avoid the risk of fire.
Install the inverter in a safe location avoiding high temperature, direct sunlight, humid air or
water.
Keep the inverter from the reach of children or persons not concerned. The inverter can only
be used at the places accredited by our company. Any unauthorized working environment
may have the risks of fire, gas explosion, electric shock and other incidents.
Install a heat sink or other cooling device when installing more than one inverter in the same
enclosure so that the temperature inside the enclosure is kept below 40℃ to avoid overheat
or the risk of fre.
Be sure to turn off the power supply before dissembling or assembling the operation keypanel
and fxing the front cover to avoid bad contact causing faults or non-display of the operator.
● Do not install the inverter in a space with explosive gas to avoid the risk of explosion.
● If the inverter is used at or above 1000m above seal level, the cooling effciency will be
reduced, so please run it by de-rating.
Do not install any switch component like air circuit breaker or contactor at the output of the
inverter. If any of such components must be installed because of the requirements of process
and others, it must be ensured that the inverter has no output when the switch acts. In addition,
it is forbidden to install any capacitor for improvement of power factor or any varistor against
thunder at the output. Otherwise it will cause malfunctions, tripping protection and damages
of components of the inverter. Please remove them as shown in the below diagram.
It will affect the service life of the inverter.If a contact is connected to the front end of input
of the inverter to control its starts and stops. Generally it is required to control it through
Control terminals. Special attention should be paid to its use in the case of frequent starts and
stops.
● Please use an independent power supply for the inverter. Do avoid using the common
power supply with an electrical welder and other equipment with strong disturbance. Otherwise
it will cause the protection or even damage of the inverter.

3.4 Precautions on Wiring
(1) For the main circuit wiring:
● While wiring the sizes and specifcations of wires should be selected and the wiring should
be executed according to the electrical engineering regulations to ensure the safety.
● It is better to use shielded wire or wire and conduit for power cord and ground the shielded
layer or two ends of wire conduit.
● Be sure to install a Non Fuse Breaker (NFB) between the power supply and the input
terminals (R.S.T). (If using ground fault circuit interrupter, please choose one corresponding
to high frequency)
● Never connect AC power to the output terminal (U.V.W) of the inverter.
● Output wires mustn’t be in touch of the metal part of the inverter enclosure, or it will result
in earth short-circuit.
● Phase-shifting capacitors, LC, RC noise filters, etc, can never be connected to the output
terminals of the inverter.
● The main circuit wire must be enough far away from other control equipments.
● When the wiring between the inverter and the motor exceeds 15 meters (shielded wire) or 50
meters (No shielded wire), much higher dV/dT will be produced inside the coil of the motor,
which will cause the destruction to the interlay or insulation of the motor. Please use a
dedicated AC motor for the inverter or add a reactor at the inverter.
● Please lower the carrier frequency when there is a longer distance between the inverter and
the motor. Because the higher the carrier frequency is the bigger the leakage current of highorder harmonics in the cables will be. The leakage current will have unfavorable effect on
the inverter and other equipment.

Attention: The parameters in the list are only for reference and should not be regarded as standard.
(2) For control circuit wiring (signal line)
● The signal line should be separately laid in a different conduit with the main circuit wire to
avoid any possible interference.
● Please use the shielded cable with the size of 0.5-2mm2 for signal lines.
● Use the control terminals on the control panel correctly according to our needs.
(3) Grounding
● Grounding terminal E Be sure to make correct grounding 220V class: The third
grounding method (Grounding resistance should be 100Ω or lower.)
380V class: The special third grounding method (Grounding resistance should be 10Ω or
lower.)
● Choose grounding wires according to the basic length and size of the technical requirements
of the electric equipment.
● Do avoid sharing grounding wire with other large power equipment such as electric welder,
17
power machine, etc. The grounding wire should be kept away from the power supply wires
for large power equipment.
● The grounding method for several inverters together should be done as the frst and second
diagrams below. Avoid the third.

(1)CFCI
Within the inverte, within the motor and the input and output leads all have the capacitance of
the ground. Due to the higher carrier frequency used, the inverter earth leakage current is large,
especially the high-capacity models. When using the GFCI, sometimes our malfunction can lead
to protection circuit. So when you use of GFCI should pay attention to the GFCI selection, while
appropriate to reduce the carrier frequency, shorten lead and so on.

Ⅵ Parameter Overview
P000 Main Frequency **
Set Range: 0.00—600.00 HZ Unit: 0.01Hz Factory Setting: 0.00
When using digital operator, the inverter will run at the setting value of P000. During running,
the running frequency can be changed by pressing the ▲ or ▼ key. During multi-speed running, the
main frequency is the first speed frequency.
When using external terminals, if P013 is set to 1, i.e. the running frequency is given by external
terminals, the first speed step is given by the potentiometer or external analog commands.
The setting of main frequency is limited by the max operation frequency.
P001 Acceleration Time
Set Range: 0.1—6500.0 Unit: 0.1s Factory Setting: 5.0
P002 Deceleration Time
Set Range: 0.1—6500.0S Unit: 0.1s Factory Setting: 5.0
Accelerat ing Time means the time needed for the inverter frequency from 0Hz to 50Hz.
Decelerating Time means time needed for inverter frequency from maximum frequency to 0Hz.
DLM1 Series inverters have 4 Accel/Decel Times. For Accel/Decel Time 2.3.4 the different
accelerating and decelerating time can be selected through the external terminals and by switching of
Accel/Decel Time according to actual needs. In the internal control multi-speed, different
Accel/Decel time can be selected through simple PLC.
P003 V/F Curve
Set Range: 0—16 Unit: 1 Factory Setting: 0
0: Wanton curve
1~16: 16 curves are wanton and available.
26
27
P004 Max. Output Voltage
Set Range: 0.1—255/510V Unit: 0.1V Factory Setting: 220/380V
P005 Base Frequency
Set Range: 0.01—600.00 Hz Unit: 0.01Hz Factory Setting: 50/60
P006 Intermediate Voltage
Set Range: 0.1—500.0V Unit: 0.1V Factory Setting: *
P007 Intermediate Frequency
Set Range: 0.01—600.00 Hz Unit: 0.01Hz Factory Setting: 2.50
P007 can set any intermediate voltage in the V/F curve. If it is set improperly, it will cause motor
over current or under torque, or even an inverter tripping.
P007 set value is limited by P005.
P008 Min. Voltage
Set Range: 0.1—50.0V Unit: 0.1V Factory Setting: * (undefined)
This parameter can set the lowest starting voltage in the V/F curve.
This setting value is limited by the voltage at the highest operating frequency.
P009 Min. Frequency
Set Range: 0.1—20.00 Hz Unit: 0.01Hz Factory Setting: *
This parameter sets the lowest starting frequency in the V/F curve.
P0010 Max Frequency
Set Range: 50.00—600.00 Hz Unit: 0.01Hz Factory Setting: 50.00
This parameter sets the highest operating frequency of the inverter
28
P011 Frequency Lower Limit
Set Range: 0.00—600.00 Unit: 0.01Hz Factory Setting: 0.00
This is set for preventing workers from false operation, avoiding overheat or some other
mechanical faults, which might be caused due to too low running frequency. When the setup frequency
is below the lower limit the inverter is running at frequency lower limit.
This set value is limited by frequency upper limit.
P012 Operation Command Source
Set Range: 0—2 Unit: 1 Factory Setting: 0
0: Digital operator;
1: External terminals or potentiometer.
IMPORTANT: CN1 JUMPER (shown at right hand side after opening inverter upper cover).
Pin 1 & 2 for panel potentiometer & Pin 2 & 3 for external terminals.
2: Communication ports, such as RS485.
P013 Operation Frequency Source
Set Range: 0—2 Unit: 1 Factory Setting: 0
0: Digital operator.
1: External terminals or potentiometer.
IMPORTANT: CN1 JUMPER (shown at right hand side after opening inverter upper cover).
Pin 1 & 2 for panel potentiometer & Pin 2 & 3 for external terminals.
2: Communication ports, such as RS485.
P014 Starting Mode
Set Range: 0—1 Unit: 1 Factory Setting: 0
Two starting modes are available for different equipment.
0: Start from the starting frequency. When P092 is set as 0, i.e. DC brake is invalid at start, it starts
running from its starting frequency. When P092 is set to any non zero value, i.e. DC brake is valid
when starting, it will first have a DC braking at start, and then start from the starting frequency. Refer
to P091 and P092.
1: Starting by Frequency track. This function can be used in the starting of large inertia load. When
starting, the inverter will trace the former speed from the set frequency downward. In case of large
inertia equipment, when restarting, it can implement the running command right away withourt
waiting for the complete stop of the equipment by tracking the former frequency to save time.
Note: When the inverter is restarted by frequency track, it will start tracking the frequency from its
set frequency downward, and search it at the highest speed. When starting, the current will be high,
and over current or stall may occur. Be sure to pay attention to the adjustment of current standard
position of frequency track. Generally, P095 should be set around 100%. The exact value should be
set according to the characteristics of mechanical load.
29
P015 Stopping Mode
Set Range: 0—1 Unit: 1 Factory Setting: 0
Two stopping modes are available for the requirements of different equipment.
0: Decelerate to stop.
When P093 is set as 0, DC braking is invalid. When DC braking is invalid, the inverter will
decelerate to the stopping frequency, and then stop output, and the motor will coast to stop. When
P093 is set for any non-zero value 0, the DC braking is valid, and the inverter will frst decelerate to
the stopping frequency, and then stop fnally by DC braking. When stopping, the DC braking is usually
used in high position stopping or for position control. Be sure to notice that frequent uses of DC
braking will cause the motor overheat.
Related parameters: P091 and P093.
1: Free-running Stop
When the inverter receives a STOP command, it will immediately stop output and the motor will
have a free running till a stop. When the free-running stopping mode is selected for the motor, DC
braking is invalid.
P016 Reverse Rotation Selection
Set Range: 0—1 Unit: 1 Factory Setting: 0
0: Reverse Run is forbidden.
1: Reverse Run is allowed.
This function is suitable when the motor cannot have reverse rotation, and to prevent workers
from false operation. When the reverse rotation is forbidden, the motor can only rotate forward, and
cannot have reverse rotation.
When the reverse rotation is forbidden, if switching between For/Rev rotation on the panel, the
panel will show Rev Run, but the motor is actually making forward rotation with the indicator lamp
indicating For Run.
P017 STOP key selection
Set Range: 0—1 Unit: 1 Factory Setting: 0
0: STOP is invalid.
1: STOP is valid.
This parameter set is only valid when P012 is set as l or 2.
When P012 is set for external terminals or communications, the STOP key on the panel can be
chosen to be valid or not. When choosing it as valid, the STOP key can stop the inverter in running.
When it needs restarting, the former running signal should be released first and then restarting is
allowable.
P018 S-Curve Time
Set Range: 0~6500S Unit: 1 Factory Setting: 0
This parameter can be set for no-impact slow start or slow stop of the inverter when starting or
stopping. When starting S-curve the inverter will make accel or decel curve of different speed rates
according to Accel/Decel Time.
When P018 is set to 0, S-curve is invalid, i.e. accelorate or decelorate in straight line.
30
Without consideration of stall, the actual Accel/Decel Time is equal to the set Acel/Decel Time
plus S-curve Time.
P019 Carrier frequency (Note: 0 ~ 15 corresponding to 0 ~ 16K Hz)
Set Range: 0~15 Unit: 1 Factory Setting: 10
The carrier frequency has some affect on the electromagnetic noise of the motor, and meanwhile
the level of the carrier frequency has certain relation with the heating capacity of the inverter and the
interference to the environment.
See the following table:

As shown in the table above, with a higher carrier frequency, the electromagnetic noise will be
lower, but the interference to othersystems must be prevented. With a lower carrier frequency, the
electromagnetic noise will be a little higher, but the heating capacity will be small. So the carrier
frequency should be set as low as possible, especially with large power machines, if the noice demand
is not so high.
P020 Starting Frequency
Set Range: 0.1—10.0 Hz Unit: 0.1Hz Factory Setting: 0.5
Starting frequency is the initial frequency when the inverter is started. If the starting frequency is
set to 4.0Hz, the inverter will begin to run at 4.0Hz .
P021 Stopping Frequency
Set Range: 0.1—10.0 Hz Unit: 0.1Hz Factory Setting: 0.5
When the inverter receives a stop command, it will immediately decelerate to the stopping
frequency, stop output or start DC brake to a final stop.
If P093 is set to 0, DC brake is invalid when stopping and the inverter will stop output.
If P093 is set to any other parameter except “0”, DC brake is valid; the inverter will stop by DC
braking.
P022 Jog Frequency
Set Range 0.00—600.00 Unit: 0.01Hz Factory Setting: 5.00
This parameter can realize the jogging function when the inverter is tested. The jog operation can
be achieved only through the external terminals, which can be set by multi-function input terminals.
Jog frequency is limited by frequency lower/upper limit. While the jog function is implemented, other
31
commands are invalid. The acceleration time of jog frequency is set by P023. When using jog function,
set external terminals to 07 or 08.
This function is only valid at stop condition. It is invalid at running. When P012 is set to 1, it is
valid.
P023 Jog Accel/Decel Time
Set Range: 0.1—25.0 Unit: 0.1S Factory Setting: 1.0
P023 corresponds to Accel/Decel Time of 0~50Hz.
P024 PLC Operation

The setting of this parameter is related to the responding speed of analog commands. The higher
the value of P078 is set, the slower the responding speed of analog commands. Too low setting of
P078 may cause the instability of frequency with fluctuation.

When the inverter is in decelerating, due to the effect of load inertia, the motor will produce a
return energy to the inverter and cause the DC voltage of the inverter to increase. So when the function
of overvoltage stall prevention is set valid and the DC voltage of the inverter becomes too high, the
inverter will stop decelerating till the DC side voltage decreases to its rated value, then the inverter
will go on to execute deceleration and the deceleration time will be extended automatically.
* Note: When the output voltage is higher the inverter will become abnormal or turn to
protection. In such case P079 can be set to 0 (Invalid), which is easy to cause overvoltage protection.
P080 Stall Prevention Level during Acceleration
Set Range: 0~200% Unit: 1% Factory Setting: 150
When the inverter is in accelerating, due to over load or too short acceleration time, the output
current of the inverter will go up quickly and exceed the rated standard level. When this happens, the
inverter will stop accelerating until the current returns under its rated value, will the inverter go on to
accelerate. When using the frequency track function the value of P080 should be lowered properly.
The greater the load initia quantity is, the smaller the value of P080 should be set. Otherwise it is
extremely easy to cause overcurrent protection.

When the inverter is in constant running, due to load fuctuation and other reasons, the current
will go up. When the current exceeds its rated value, the inverter will lower the output frequency.
When the output current returns to its normal range the inverter will accelerate again to its set
frequency.

P082 Stall Prevention Level during Deceleration
Set Range: 0~200% Unit: 1 Factory Setting: 180
When this parameter is set to 0, the stall prevention function is invalid.
P083 Overtorque Detect Level
Set Range: 0~200% Unit: 1% Factory Setting: 0
When the output current exceeds the over torque detection level and also exceeds half of the set
over torque detection time (factory setting: 1.0s), the over torque detection will begin to indicate, and
the corresponding multi-function contact will act. When it exceeds the set time value, the inverter will
turn into self-protection. But when this parameter is set to 0, the over torque detection will be invalid.
P084 Overtorque Detect Time
Set Range: 0.1~20.0S Unit: 0.1S Factory Setting: 1.0
When the inverter detects that the output current has exceeded the motor current set value, the
inverter begins to calculate the over torque time. When the over torque time has exceeded half of the
over torque detection time, the corresponding multi-function output contact will act, the over torque
alarm will be produced, while the inverter will continue running. When the over torque time has
exceeded the set detection time (set by P083), the inverter will turn into self-protection, display the
fault signal and stop output.
P085 Rated Motor Voltage
It is set according to the rated voltage value of the namplate. For 230V class inverters the default is
220, while for 400 V class inverters the default is 380V.
P086 Rated Motor Current
It is set according to the rated value of the namplate. This parameter can be used to restrict output
current of the inverter to prevent overcurrent and protect the motor. If the current of the motor has
exceeded this value the inverter of AC motor will turn into self-protection.
P087 Motor Poles
Set Range: 02~10 Unit: 1 Factory Setting: 04
This parameter is set for the pole number of the motor according to the namplate of the motor.
P088 Rated Motor Revolution
Set Range: 0~9999 Unit: rpm Factory Setting: 1440
This should be set according to the actual revolution of the motor. The displayed value is the
same as this parameter. It can be used as monitoring parameter, which is convenient to the user. This
parameter set value corresponds to the revolution speed at 50Hz.
P089 Motor No-load Current
Set Range: 0~100 Unit: 1 Factory Setting: 40
The setting of Motor no-load current will affect the quantity of slip compensation. 100% current
is the rated current of the motor.
P090 Slip Compensation
Set Range: 0~1.0 Unit: 1 Factory Setting: 0.0
When the inverter drives the motor, the slip will become bigger due to the increase of load. This
46
parameter can be set for slip compensation to decrease the slip and make the running speed of the
motor closer to synchronous speed of revolution.
P091 DC Braking Voltage
Set Range: 0.0~20.0% Unit: 0.1% Factory Setting: 2.0
This parameter is set for the DC brake voltage to of the motor at starting and stopping. It can be
adjusted for different brake voltage. When adjusting the parameter it must be increased slowly from
lower values to high values until the suffcient brake torque is achieved.
100% voltage is the voltage at maximum frequency.
P092 DC Braking Time at Starting
Set Range: 0.0~25.0S Unit: 0.1S Factory Setting: 0.0
This parameter is set for DC Brake at starting and giving the lasting time of DC Brake current of
the motor at starting. If it is set to 0 it means DC brake is invalid.
DC braking before running is normally applied in the cases in which the load is movable in the “stop”
state, such as windmill and other machines. Because of the load existing before the inverter drives, the
motor is always in a free running state, with an uncertain running direction. So the DC braking can be
executed before starting the motor to prevent the inverter from tripping.
P093 DC Braking Time at Stopping Set
Set Range: 0.0~25.0S Unit: 0.1S Factory Setting: 0.0
P094 Frequency track Time
Set Range: 0.0~20.0S Unit: 0.1S Factory Setting: 2.0
This parameter is set as frequency track time when the inverter restarts by the frequency track
method after the external errors or temporary power off. For the starting and stopping of some large
inertia load, because of its large inertia, if restarting the machine after its complete stop, it will waste
much time. But if the frequency track function is started, it is not necessary to wait for the machines
to come to a full stop for restart. The inverter will search the speed from high to low with the set

After tracking it it will continue to accelerate to reach the set frequency.
P095 Frequency track Current Level
Set Range: 0~200% Unit: 1% Factory Setting: 150
When the inverter search speed this set value sould be taken as the level for output current. When
the output current is higher than this level the inverter will suspend searching. When the current is
restored below the current level it will then execute the frequency track again.
After starting the frequency track please decrease properly the frequency track current level
according to the actual conditionof load. Otherwise it is extremely easy to cause overcurrent protection.
P096 Restart after Instantaneous Stop
Set Range: 0~1 Factory Setting: 0
0: Invalid, i.e. the inverter will not restart after an instantaneous stop.
1: Frequency track Start. Refer to P094.
P097 Allowable Power-off Time
Set Range: 0.1~5.0S Unit: 0.1S Factory Setting: 0.5
This parameter is set for the maximum allowable power off time. If exceeding the set time the
inverter will continue to stop input after power on. To execute the restart it needs to follow the general
starting procedures.
*Attention: When using this function special attention should be paid to the safety. During the
process of instantaneous power off and power on the inverter may restart. It is easy to produce danger.
Be careful to use this function.
P098 Number of Abnormal Restart
Set Range: 00~10 Unit: 1 Factory Setting: 00
After the abnormal conditions (such as overcurrent, overvoltage) happen the invrter will
automatically reset and restart. If the starting mode is set for general mode it will start according to
the general mode. If it is set for frequency track start it will start in the frequency track mode. After
start it will restore the set number again if there is not anything unusual happened within 60 seconds.
If there is any error and it reaches the set number the inverter will not have input. It can only be started
after reset. If P098 is set to 0 the inverter will not carry out the functions of automatic reset and restart.
P099 Auto Voltage Regulation
Set Range: 0~1 Unit: 1 Factory Setting: 1
0: Invalid
1: Valid
When the input power supply is not stable and if the voltage is over high the operation of the
motot with the power of exceeding the rated voltage will cause the temperature of the motor increasing,
the insulation damaged and the output torque unstable. This auto voltage regulation can automatically
stablize the output voltage within the rated voltage range of the motor under the condition of unstable
output power supply
When this function is set to invalid the output voltage will fluctuate.
48
P100 Auto Torque Compensation
Set Range: 0.1~10.0% Unit: 0.1% Factory Setting: 2.0
This parameter can be set for the auto output of extra voltage when the inverter is running for higher
torque, which can compensate for the insuffcient torque at lower frequency. The torque compensation
should not be too big and it should be set slowly from low to high according to the actual situation.
Insufficient compensation will result in the insufficient torque of the motor at low frequency. And over
compensation will lead to too bigger torque, which will produce a shock to the machine and even
result in a trip of the inverter under serious situation.
P101 Auto Energy Saving
Set Range: 0.0~20.0% Unit: 1% Factory Setting: 0
When it is set to 0 this function is invalid. When Auto energy saving function is opened the
inverter will run at the full voltage during acceleration and deceleration. During the operationa at
constant speed the inverter can automatically calculate the optimum voltage value according to the
power of load to supply it to the load in order to meet the the goal of energy saving.
The output voltage can be regulated automatically and it can be decreaed by max.30% of normal
output voltage.
P102 PID Constant P
Set Range: 0.0~1000% Unit: 1 Factory Setting: 100

control.
P103 PID Constant I
Set Range: 0.1~3600 Unit: 1 Factory Setting: 5.0
The integral time (I) is set for the reaction speed for PID. The larger the I value is the slower the
reaction speed is. But if the integral time value is set too small, it will cause vibration.
P104 PID Constant D
Set Range: 0.01~10.0 Unit: 0.01 Factory Setting: 0
This didderential time (D) is set for the depression operation of PID. The larger the D value is,
the more obvious the depression operation is. When D is set to 0, it means this function invalid.
P105 PID Constant Target Value
Set Range: 0.0~100.0 Unit: 0.1 Factory Setting: 0.0
This target value can be set through external voltage signal or the digital operator.100% target
value is corresponding to the frequency quantity at +10V.

Appendix 3: MODBUS Communication Protocol
When using the RS485 communication interface, each of the inverters must set its own address
so that the computer can use this individual address to carry out the control.
1: Communication port terminal setting
The communication protocol
has two modes: RS485Communication Port
⑴ RTU mode (Remote Terminal Unit)
⑵ASCII mode(American Standand Code for imformation interchange)
Information of code.
RTU mode: Each of 8-bit data is composed of two 4-bit (hexadecimal), for example: 64H
ASCII mode: Each of 8-bit data is composed of two ASCⅡbyte, for example:
One 1-bit data 64H (hexadecimal) is composed of ASCⅡ byte“64”, included“6”(36H) and
“4”(34H).

⑷ LEN: Data length, the length of D(n-1)~D0
⑸ DATA: data content, n*8-bit
⑹ LRC: Longitudinal Redundancy Check
RTU mode: get CRC(cyclical Redundancy Check).
The CRC calculation method is following:
⑴ make a 16-bit register and set value 0FFFFH(call CRC register)
⑵ done frst byte of data Exclusive OR with low byte of 16-bit CRC register and save the
result to CRC register
⑶ done 1 bit right shift with CRC register and fll zero to left bit, then check low bit of CRC
register.
⑷ if the low bit is zero, then do repeat setp3, else CRC register do Exclusive OR with
0A001H.
⑸ done repeat step 3 and 4,until CRC register done right shift 8 times,then the byte is fully
done.
⑹done repeat step 2 to 5 for the next byte of data, until process completely all data. The last
data of CRC register is CRC value.
When send CRC value in command data, low bytes must change the sequence with high
bytes, i.e. low bytes will be sent frst.
