 NOTICE

Please read all the operation manual before operating the set and keep this manual for further
reference.

Installation of MAM—KY** compressor controller can be performed only by professional technicians.

Installation position shall be considered carefully in order to ensure good ventilation and reduce
electromagnetic interference.

Wiring shall be performed respectively according to regulations for heavy and weak current to reduce
electromagnetic interference.

RC snubber must be connected to the two terminals of coil (such as AC contactor ,valve, etc),which
are controlled by relay output.

Port connection shall be inspected carefully before power on.

Correct ground connection (the third ground)can help increase product capacity of resisting signal
interference.

Set rated current of motor: the max current of motor/1.2.

Features：
● Multiple run mode optional.
● 7 inch color screen ,with button and touch penal.
● Support real time power consumption and accumulative power consumption measurement.
● Scheduled on/off function and scheduled pressure function optional
● More accurate in writing frequency to control inverter through 485 communication
● Free to control all inverter supporting MODBUS RTU protocol.
● Open phase ,current overload ,current unbalance ,high voltage, low voltage protection for motor.
● High integration, high reliability, high cost performance

8, Block control and network communication

8.1 Block Control：

MAM6080 controller can work in block mode with MAM series compressor (with communication
function).16 pieces compressors can work together in a net at most. Block mode can be set as VSD
–VSD,PF-PF or VSD- PF .The cable connection for block mode control is as below....1,2 terminals ( RS485
terminal ) are used for block mode.
In BLOCK PARAMETER SET menu, set as VSD-VSD or PF-PF,master chooses compressor to work
according to the TOTAL RUN TIME. Compressor with shorter running time is chosen to start and compressor
with longer running time is chosen to stop with priority.
In BLOCK PARAMETER SET menu,, set as VSD-PF, master works first, other compressors work
according to the TOTAL RUN TIME. Compressor with shorter running time is chosen to start and compressor
with longer running time is chosen to stop with priority.

Page 33 Total 42
 No.1 No.2 No.3 No.4 No.N

Pitcure8.1.1.1
Compressor with COM ADD 0001 is master, others are slave. Any one MAM series compressor can be set
as master or slave.
8.1.1 Block Control Set：
8.1.2.1 Set as Master：
Set rhe COM ADD in USER PARAMTER to 001
According to user requirement, set COM MODE, BLOCK NUMBER, TURN TIME, BLOCK LOAD P,
BLOCK UNLD P, BLOCK DELAY , BLOCK MODE .After set, controller needs to be powered off and restart
to save setting.
8.1.2.2 Set as Slave：
When MAM6080 controller serves as slave, it is only necessary to set COM MODE as BLOCK, COM
ADD can be set from2-16 in sequence according to the quantity of compressors, .BLOCK STATUS set as
SLAVE.
8.1.2 Start, Stop Block mode：
Make sure block cables connect correctly, also the parameter of compressor in block mode is set correctly.
Activate master, master controls the compressor in net automatically according to the AIR P detected. When
manually stop the master, block control stops at the same time, thus, master will no longer send command to
compressors in net.

8.2 Network Communication

MAM6080 controller supports MODBUS RTU protocol and can serve as slave when connects with other
equipment .It is supports 03、06、16 MODBUS command. Communication baud rate: 9600BPS, 1 start bit, 8 data
bits, 1 stop bits and even parity. For MODBUS register address, please see MODBUS communication manual.

9, Inverter Control

485 communication control

There is one spare port for RS485 to communicate with inverter. User can start or stop controller through
RS485,it transfers the output frequency based on PID calculation to inverter through 485 port. This is how to
adjust inverter output frequency and realize constant pressure and temperature. The baud rate is fixed as 9600BPS
Page 34 Total 42
when RS485 control inverter. Different inverter data format can be set in INVERTER SET in FACTORY
PARAMETER. MOTOR INVERTER is suggested to be set as 0001, FAN INVERTER is suggested to be set as
0002.
In order to be compatible with different inverter, set the item such as CURR(R) ADD, VOLT(R) ADD, FREQ(R)
ADD , POWE(R) ADD, RUN (W) ADD, ERR STATE(R) ADD, FREQ(W) , RESET(W) ADD. For different
inverter, amplification of current, voltage, frequency, power is different. Write a formula to every parameter to
transfer current, voltage, frequency, power of inverter to one digit data.
Relative parameter introduction is as below, please take the Schneider 67,71 inverter as example.

Item Data Set Explanation

NAME：
RUN(W)
2135 Corresponding address 1 of inverter start command
ADD1：
This data is inverter start data (please refer to communication
RUN VALUE： 0001
chapter in inverter manual for different inverter.)
RUN(W)
2135 Corresponding address 2 of inverter start command
ADD2：
This data is inverter start data (please refer to communication
RUN VALUE： 0001

STOP(W)
2135 Corresponding address of inverter stop command
ADD：
This data is inverter start data (please refer to communication
RUN VALUE： 0001
chapter in inverter manual for different inverter.)
RESET(W)
2135 Corresponding address of inverter reset command
ADD：
This data is inverter start data (please refer to communication
RUN VALUE： 0001
chapter in inverter manual for different inverter.)
FREQ(W) Corresponding register address of inverter running frequency
2136
ADD： source
The REC value is frequency value with one decimal. Use formula
to transfer to corresponding value based on different inverter and
send it to inverter.
Example： 50HZ running frequency，REC value:500
For inverter with write frequency of 2 decimals, formula:
FREQ(R) = REC*0001÷0001
REC**0001÷0010
For inverter with write frequency of 1 decimal, formula:
REC**0001÷0001
For the inverter whose max output frequency is in corresponding
with 10000,the formula :REC*0020÷0001
STATE(R)
2135 Read inverter running status address
ADD：
R AND Check if inverter has run the formula(please refer to
RUN S =
0001=0001 communication chapter in inverter manual)

 Set the data format of controller and inverter communication. This
set should be consistent with inverter communication format
8N1-N: 1start bit,8 data bits,1 stop bit, no parity bit
COM FORM 8N1-N 8N1-E: 1start bit,8 data bits,1 stop bit, even parity bit
8N1-O: 1start bit,8 data bits,1 stop bit, odd parity bit
8N2-N: 1start bit,8 data bits,2 stop bit, no parity bit
Note: Communicate with inverter, the baud rate is fixed:9600
FREQ(R)
0C82 Read inverter frequency address(refer to inverter manual )
ADD
Calculate inverter frequency formula. Controller will transfer the
FREQ(R) = REC*0001÷0001
frequency to one decimal.
VOLT(R)
0C88 Read inverter voltage address
ADD
Calculate inverter voltage formula. Controller will transfer the
VOLT(R) = REC*0001÷0001
voltage to one decimal
CURR(R)
0C84 Read inverter current address
ADD
Calculate inverter current formula. Controller will transfer the
CURR(R) = REC*0001÷0001
current to one decimal
POWE(R)
0C8B Read inverter power address
ADD
R AND
ERR S = Inverter reports error formula or not
0000≠0000
EMERGENCY
2135 Corresponding add of inverter emergency stop command
ADD
This data is inverter free stop data (please refer to communication
RUN VALUE 0001
chapter in inverter manual for different inverter.)

Firstly，controller sends 0 to corresponding register of“STATE(R) ADD” through inverter. After delay for a
while, sends 1 to corresponding register of“RUN1(W) ADD”. After another delay, reads“ RUN S”register, and
judges if the inverter is running based on the set formula. Calculate the output frequency based on the comparison
of pressure detected and pressure set and send this value to corresponding address of“FREQ(R) ADD” through
formula operation.
