Additional parameter settings

Table 3- 2 Parameter settings on the master converter and on the slave converter:
Parameter
p51799 Mode of operation
p51800 Position in the topology
p51801 Amount of send data
p51802 Number of power units
p51803 n+m mode
p51804[..] Send data
p51805 Bus terminator
p51806 Station address
p51807 Telegram failure time
p50082 Field operating mode
p50076[..] Reduction in the rated unit DC cur-
rent
3)
p50078[..] Rated value for supply voltage
p50100 Rated motor current
p50357 Threshold for interrupted tachometer
1)
If the number of power units that are ready to operate for n+m operation is less than the value set in p51802, then fault
message F60044 is output, followed by shutdown (OFF2).
2)
= 1 at the two outermost units (= at the physical ends of the bus line)
= 0 on all of the other units
3)
Note: In conjunction with r50072[..], ensure that p50076[..] is correctly set, as described in the List Manual under
p50076[..].
