Example of parameter operation in PKW area
Example description
In applications, the master and the frequency converters communicate with
messages in PPO structure. Among the 5 PPOs stated in fig. 13-5 "PPO type" on
page 204, PPO 1, PPO 2 and PPO5 apply both PKW area and PZD area. In fol-
lowing examples, PKW area data frames are taken from complete PPO message
to describe its request and response data frames.
Example 1
Reading value of parameter b1.20 'Acceleration time 1'. 0x01 is the parameter
group, 0x14 is the index No. of the function code within the parameter group,
then request and response data frames in PKW area are shown in table below:
ID IND VALUE_high VALUE_low
Request data frame of PKW area 0x0001 0x0114 0x0000 0x0000
Response data frame of PKW area 0x0001 0x0114 0x0000 0x0032
