• p0494[0...n]
• p0495
• p2596
• p2597
• p2598
• p2599
• p2600
Parameter p0494 corresponds to parameter p0495 regarding its significance. In addition,

Referencing with several zero marks per revolution

The drive detects several zero marks per revolution when using reduction gears or
measuring gears. In this cases, an additional BERO signal allows the correct zero mark to be
selected.
Example with a reduction gear
Figure 8-18
The diagram shows an application example for referencing with several zero marks per
revolution and selecting the correct zero mark using a BERO signal.
