Регистры частотного преобразователя IDS-Drive серии B

Регистры частотного преобразователя серии B.

В стандартной документации тема регистров для взаимодействия с частотными преобразователями серии B практически не раскрыта, что вызывает ряд затруднений при организации управления через интерфейс RS-485 (Modbus RTU). 

Предлагаем вашему вниманию более подробное описание регистров

Стандартная структура RTU-кадра:


STARTT1-T2-T3-T4 (3, 5 bytes of transmission time)
SLAVE ADDRCommunication address: 1~247
CMD03H: read slave parameters; 06H: write slave parameters
DATA (N-1)Data: Function code parameter address, number of function code parameter, value of function code parameter 
DATA (N-2)
...
DATA 0

CRC CHK high-order

Check value: CRC
CRC CHK low-order
ENDT1-T2-T3-T4 (3, 5 bytes of transmission time)
Command code (CMD): 03H, read N words (at most continuously read 12 words). For example, the inverter of which slave address is 01, memory starting address is F02, when  continuously reading two words, and then the host command information as below:

The definition of communication data address:

This part is the address definition of communication data and used to control the operation of the inverter, obtain inverter state information and related function parameters settings, etc.

Function code parameter address rules

High and low bytes range respectively: high byte F0-FE (F group), A0~A2 (F15~F17 group); low byte 00~FF. For example, if visit F04.02, so the function code address is 0xF40C.

Note: F14 group: manufactures settings parameters, neither can read this group of parameters, nor change this group of parameters; F17 group: can read this group of parameters, but can not change parameter. When inverter is in operation, some parameters cannot be changed; some parameters cannot be changed no matter what state inverter is; when changing the function code parameters, you also should note the parameter settings range, unit, and relate instructions.

 

Function code group
Communication visit address
Function code address of communication change RAM
F00~F140xF000~0xFEFF0x0000~0x0EFF
F15~F170xA000~0xA2FF0x4000~0x42EF

Because the EEPROM is frequently stored, it will reduce the service life of EEPROM. As for users , some function code does not need to be stored under the mode of communication, and only need to change value of RAM to satisfy the usage requirements. This function can be activated only by changing the high-order of the corresponding code address from F to 0.

High and low bytes range respectively: high byte 00~0F (F group); low byte 00~FF.

For example:

Function code F04.12 is not stored in the EEPROM, and set the address to 040C.

Function code F15.51 is not stored in the EEPROM, and set the address to 4033.

This address can only be used for chip RAM, and cannot used as function of reading, if doing so then invalid address. For all parameter, it can realize this function by command code 07H.
