Using the parameter channel
The digital servo amplifiers of the PMCtendo DD4 series have to be adapted to the circumstances
of your machine. The parameters for the controllers are set using either the setup Software PDrive
or via the PROFIBUS.
5.1
Read/write an amplifier parameter
Read (AK = 1) or write (AK = 3) amplifier parameters
To read or write an amplifier parameter, which is recognized by the parameter number (PNU), to the
volatile
memory of the PMCtendo DD4. The parameters that are stored in the PMCtendo DD4 can
be transferred to the
non-volatile
memory by using the command “non-volatile parameter save”
(PNU 971).

Summary of the parameter numbers
All the parameter numbers for PMCtendo DD4 are listed in numerical order in the table in Chapter
5.2.1, with a short description. The parameter numbers in the range 900 – 999 are profile-specific
for the PROFIBUS drive profile PROFIDRIVE. Parameter numbers > 999 are manufacturer- spe-
cific.
For better understanding, you can look up the ASCII commands which are in the column
“PMCtendo DD4 ASCII command” in the user manual for the Setup Software PDrive.
This section deals only with parameters that refer to the PROFIBUS expansion card and have not
already been described in the setup software manual. The attachment runs via the ASCII-com-
mands.
