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 9-45 Design with a gear between the motor and load
The diagram shows an application example for referencing with several zero marks per
revolution and selecting the correct zero mark using a BERO signal.
By using a reduction gear between the motor and the load, the drive detects several
revolutions of the motor per mechanical revolution of the load - and therefore also several
encoder zero marks.
The higher-level control/position control when referencing requires a unique reference
between the encoder zero mark and the machine axis (load). This is the reason that the
"correct" zero mark is selected using a BERO signal.
