Example 3: Write data 2 to parameter P0804
To write data to P0804, request ID is set to 2 (Modify parameter value - word), Para Page
Select should be set because the parameter address is greater than 2000. The address of
P0804 is 0x0804, which is 2052 in decimal, if set Page Select to 1 (bit 15 of IND is 1), then
the Basic PNU is 2052 – 1*2000 = 052 (0x34), thus, the data sequence are as follows:
Master  CME-PD01: 2034800000000002 write data to P0804

All parameters values in VFD-E series are 16-bit, so the data may be transferred to PWE2
(4th word).
NOTE
VFD-E series will write the data to EEPROM. When using PKW to change the value of
parameter, the data will be written to EEPROM directly. However, the frequent writing action
may result in EEPROM damage and the EEPROM will have no capability of directly
saving data. So please pay close attention on it.
Example 4: Read diagnostic data
User can use the special address to read the current diagnostic data. Please refer to Section
6.2 for details. The diagnostic address starts from 0x7500 to 0x7504 (5 words). To read
diagnostic data in these addresses, request ID is set to 1, Para Page Select should be set
because the parameter address is greater than 2000. The address 0x7500, which is 29952
