Example 2
Modifying 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. If
the modifying value is 0x0064, 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 0x0002 0x0114 0x0000 0x0064
Response data frame of PKW area 0x0002 0x0114 0x0000 0x0064

Example 3
Modifying 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. If
the modifying value is 0xFFFF, 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 0x0002 0x0114 0x0000 0xFFFF
Response data frame of PKW area 0x0007 0x0114 0x0000 0x0064

PZD process data area
PZD process data area description
When the master is sending a request message to the slave, PZD1 and PZD2 in
PZD process data area are respectively corresponding to control word (CW) and
reference frequency (REF) and PZD3 to PZD10 (number depending on PPO
type) are written as 0. When the slave returns a response message to the mas-
ter, PZD1 and PZD2 in PZD process data area are respectively corresponding to
status word (SW) and actual output frequency (ACT), and PZD3-PZD10 are cor-
responding to status monitoring values (such as output current, output voltage,
AC bus voltage, etc.) set by function code parameter H0.10 to H0.17.
For control word, status word and parameter addresses, see descriptions in
chapter 13.2.4 "Communication Mapping Register Address Distribution" on
page 195.
