● Referencing to an external zero mark connected via an input terminal (CU - parameter
● The position of the zero mark that is output is synchronized to the zero position of the
Adjustable zero mark offset at the TM41 output
An offset of the pulse grid can be set for the the zero mark position of the encoder emulation
using p4426.
Example of a pulse number - step-up ratio
The leading encoder outputs three pulses and one zero mark per revolution. However, the
application requires 8 pulses per revolution. By setting p4408 and p4418, the required 8
pulses a revolution are available at X520 of the TM41.

NOTICE
Original encoder with several zero marks
If the original encoder has several zero marks / positions, then supplementary
conditions must be selected for the zero mark.
