•The 7200MA inverter has a built-in RS-485 port for monitoring inverter status and
reading the parameter setting. Under the remote mode operation, the inverter status
and the parameter settings can be monitored. Moreover, the user can change the
parameters setting to control the motor operation.
•7200MA will use MODBUS protocol to communicate with external units by
means of the cable line form RS-485 port.
•Parameter definition is as follows：
•Sn-36： inverter station address, setting range 1~31.
•Sn-37 = 0：1200bps (bps: bit / sec)
= 1：2400bps
= 2：4800bps
= 3：9600bps
•Sn-38 = 0：no parity
= 1：even parity
= 2：odd parity
•Sn-39 = 0： Deceleration to stop with Bn-02 (deceleration time), when RS-485
= 1： Coast to stop
= 2： Deceleration to stop with Bn-04 (deceleration time), when RS-485
= 3： Continue to run (will stop if the key stop is pressed)
•Every data stream has a data length of 11 bits : 1 start bit，8 data bits，1 parity bit
and 1 stop bit. If Sn-38=0, the parity bit is 1.
•3 different commands are used for communication between the inverter and
external units:
a. Read command : external units to read the memory address of the inverter.
b. Write command : external units to write the memory address of the inverter in
order to control the inverter.
c. Circuit test command : To test the communication status between the inverter
and external units.
•The change of setting Sn-36, Sn-37, Sn-38 will be effective in the next start time
after turning off the inverter.
•Do not make the DRIVE/PRGM changeover while writing the date into the
inverter through RS-485 port.
