• Set the Device Object Instance ID using drive parameters 5311 and 5317.
Default: Both 5311 and 5317 = 0, which causes the MAC ID to "double" as the
Device Object Instance. For Device Object Instance values not linked to the MAC
ID, set ID values using 5311 and 5317:
– For IDs in the range 1 to 65,535: Parameter 5311 sets the ID directly (5317
– For IDs > 65,335: The ID equals 5311's value plus 10,000 times 5317's value.
