Command
7EH ADDR 07(08) See Remark Parameters BCC 0DH
Number of byte 1 2 2 4 4 4 1
Response of
slave
7EH ADDR 00 See Remark Parameters BCC 0DH
Number of byte 1 2 2 4 4 4 1
Remark
Index of command is comprised by the group No. of parameters, and HEX number of Parameter No., for example:
If parameters of F1.11 is to be read, then Index of command=010B;
If parameters of F9.16 is to be read, then Index of command=0910;
If parameters of FF.01 is to be read, then Index of command=0F01;
If parameters of FP.01 is to be read, then Index of command=1301;
Relationship between the decimal value and Hex. Value

F0 0 00H F8 8 08H
F1 1 01H F9 9 09H
F2 2 02H FA 10 0AH
F3 3 03H FF 15 0FH
F4 4 04H FH 16 10H
F5 5 05H FL 17 11H
F6 6 06H Fn 18 12H
F7 7 07H FP 19 13H
Valid data 0~FFFF(That is: 0~65535)
Example ~010713010000024D\r Set FP.01 to 0, all the parameters are enabled to be changed.
Note:
The usages of group 7 and group 8 commands are the same. To avoid damaging EEPROM, the parameters changed frequently
should be saved in DSP RAM by group 8 commands if not necessarily written in EEPROM.
2) Example (Turbo C 2.0): Send the command of running the drive, stopping the drive and setting the frequency (need to
set F0.00=2, F0.03=2 first.)
