②
Frequency command Parameter
1st byte : 0x00
2nd byte : 0x04
Setting data
Output frequency
ⅹ
100
Ex) The case of output frequency command is 60 Hz
Data 6000 transmit
1st byte : 0x17
2nd byte : 0x70
(6) Response data in Prameter setting
Note) Response frame when you send a command for setting a parameter
When the data cannot be stored due to the attempt to store data while the unit
is running, the setting data will not be stored and the original data will be
responded.
(7) 16bit CRC generation
The step of CRC-16 generation is as follows:
z
All of 16-bit register is 1. 0xffff
z
The exclusive OR of 16-bit register and 8-bit register.
z
Shift right side 1bit a 16-bit register
z
If the result of step 3 is 1, exclusive OR 16-bit register and 0xa001.
z
Execute 8 times step 3 and step 4.
z
Execute step 2~6 until data completion
z
Exchange the step 6 result of higher 8bit and lower 8bit.
