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 8 PPOs stated in fig. 14-2 "PPO telegram
type" on page 278, PPO1, PPO2 and PPO5 apply both PKW area and PZD area.
In following examples, PKW area data frames are taken from complete PPO mes-
sage to describe its request and response data frames.
The following examples are all based on Frequency Converter EFC 5610 and
PROFIBUS card.
Example 1
Reading value of parameter E0.26 'Acceleration time'. 0x30 is the parameter
group, 0x1A 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 0x301A 0x0000 0x0000
Response data frame of PKW area 0x0001 0x301A 0x0000 0x0032
