BECKHOFF AX2000 PROFIBUS DP communication profile - Manual (Page 22)

4.2.2 Standard PROFIDRIVE parameters
4.2.2.1 PNU 940/911: PPO type write/read
These parameters describe the numbers of the supported PPO-types write und read.
Since only PPO-type 2 is supported (see Chapter 3), this parameter is always set to 2.
4.2.2.2 PNU 918: PROFIBUS node address
With this parameter the PROFIBUS - node address of the amplifier can be read.
AX2000/2500
The range of addresses can be extended from 1..63 to 1..127 with the ASCII-command MDRV.
Setting up the station address, see page 8.
4.2.2.3 PNU 963: baud rate
This parameter defines the index of the baud rate that is used for PROFIBUS communication, and
can only be read. The baud rate is given out by the PROFIBUS-master.
The table below shows the indices with the according baud rates (in kBaud):
Index 0 1 2 3 4 5 6 7 8 9
Baud rate 12000 6000 3000 1500 500 187.5 93.75 45.45 19.2 9.6
4.2.2.4 PNU 965: PROFIDRIVE profile number
This parameter can be used to read out the number of the PROFIDRIVE profile. Profile Number 3,
Version 2 is used.
4.2.2.5 PNU 970: default parameters
With this parameter you can reject all the parameters that are set and load the manufacturer’s
default values.
4.2.2.6 PNU 971: non volatile saving of parameters
With this parameter you can save all the parameter settings to the EEPROM. To do this, the para-
meter must have the value PWE = 1 when the transfer takes place.
