The pulse/direction interface is assigned an encoder channel. If you are using a motor
encoder, it is always assigned encoder channel 1. This means you need to select
encoder channel 2 for the pulse/direction interface.
Select the integrated HTL/TTL encoder evaluation of the CU305 as the input for the
pulse/direction interface.
the preferred maximum motor speed. The following formula applies:
Pulse number = (max. clock frequency · 60)/max. speed
Example: If the controller has a maximum clock frequency of 100 kHz and the motor
being used is to run at its maximum rated speed of 3000 rpm, the resulting pulse number
will be 2000.
