2.6.2.2 DPRAM parameters
[100...104]
IE SYN 0...4 Synchronous communication (high priority)
between the DGF and drive.
Contains the drive parameter number written on the drive (0 = no parameters)
[110...114] EI SYN 0...4 Synchronous communication between the drive
and DGF.
Contains the drive parameter number read from the drive (0 = no parameters)
[120...129] IE ASYN 0...9 Asynchronous communication (low priority)
between the DGF and drive.
Contains the drive parameter number written by the DGF (0 = no parameters)
[140...149] EI ASYN 0...9 Asynchronous communication between the
drive and DGF.
Contains the drive parameter number read by the DGF (0 = no parameters)

When the DGF is in “Run” status, the automatic synchronous
and asynchronous communications cyclically write several
drive parameters. When the DGF is not in “Run” status, the
drive parameters controlled by automatic communications are
not cyclically written.
The bits of parameter 297 allow or inhibit modification of the
drive parameter value, when the DGF is not in “Run” status.
The first 5 bits of the low word are associated respectively
with the 5 synchronous communications. The first 10 bits of
the high word are associated respectively with the 10
asynchronous communications.
297 [n] = 0 drive parameter is forced to zero
297 [n] = 1 drive parameter keeps the last value calculated by DGF
where n: 0...31 is the bit number of the double word.
As default value, the 297 parameter is set to zero.
