Write request: Changing the automatic restart mode (p1210)
Parameter p1210 defines the automatic restart mode:
●
PKE, bit 12 … 15 (AK): = 7
(change parameter value (field, word))
●
PKE, bit 0 … 10 (PNU): = 4BA hex
(1210 = 4BA hex, no offset, as 1210 < 1999)
●
IND, bit 8 … 15 (page index): = 0 hex
(offset 0 corresponds to 0 hex)
●
IND, bit 0 … 7 (subindex): = 0 hex
(parameter is not indexed)
●
PWE1, bit 0 … 15: = 0 hex
●
PWE2, bit 0 … 15: = 1A hex
(26 = 1A hex)

Write request: Assign digital input 2 with the function ON/OFF1 (p0840[1] = 722.2)
In order to link digital input 2 with ON/OFF1, you must assign parameter p0840[1] (source,
ON/OFF1) the value 722.2 (DI 2). To do this, you must fill the telegram of the parameter
channel as follows:
●
PKE, bit 12 … 15 (AK): = 7 hex
(change, parameter value (field, word))
●
PKE, bit 0 … 10 (PNU): = 348 hex
(840 = 348 hex, no offset, as 840 < 1999)
●
IND, bit 8 … 15 (page index): = 0 hex
(offset 0 ≙ 0 hex)
●
IND bit 0 … 7 (subindex): = 1 hex
(command data set, CDS1 = index1)
●
PWE1, bit 0 … 15
: =
2D2 hex
(722 = 2D2 hex)
●
PWE2, bit 10 … 15: = 3f hex
(drive object - for SINAMICS G120, always 63 = 3f hex)
●
PWE2, bit 0 … 9: = 2 hex
(index or bit number of the parameter: DI 2 = r0722.2)
