4.2. Commands

Here are the communication commands available.

Command

Function

R command

Reads the data with the specified communication number.

W command

Writes the data with the specified communication number. (RAM and EEPROM).

P command

Writes the data with the specified communication number. (RAM).

G command

Reads the data with the specified communication number. (For binary mode only.

Dummy data is required for this command.)

 

X command

Block communication (Computer -> Inverter)

Y command

Block communication (Inverter -> Computer)

„W (57H) (RAM*1 /EEPROM*2 write)

This command is used to write new data into the parameter specified using it communication num- ber. It writes data into the RAM and EEPROM. For parameters whose settings cannot be stored in the EEPROM (e.g., parameter with the communication number FA00), the W (57H) command writes data into the RAM only. It cannot be used to write data into read-only parameters (e.g., parameter with the communication number FD?? or FE??).

Each time an attempt to write data is made, the inverter checks if the data falls within the specified range. If this check reveals that the data falls outside the specified range, the inverter will reject it and return an error code.

- Ex.: Setting the deceleration time (communication number: 0010) to 10 sec.

Notice

♦Do not write the same parameter to the EEPROM more than 10,000 times. The life time of EEPROM is approximately 10,000 times.(Some parameters are not limited, please refer to the “9.Parameter data “) The lifetime of EEPROM is approximately 10,000 times. When using the TOSHIBA inverter protocol and the data does not need to be records, use P command (the data is written only to RAM).

„Explanation of terms

*1: The RAM is used to temporarily store inverter operation data. Data stored in the RAM is cleared when the inverter is turned off, and data stored in the EEPROM is copied to the RAM when the inverter is turned back on.

*2: The EEPROM is used to store inverter operation parameter settings, and so on. Data stored in the EEPROM is retained even after the power is turned off, and it is copied to the RAM when the inverter is turned on or reset.
