Description
Selection of the number of channels used. The channels are assigned in
ascending order.
Selection of the type of PTO pulse output (Page 14).
Selection of the interface used for the pulse output:
•
•
Selection of the minimum time between a change in direction and the out-
put of the first pulse in the new direction.
Enables the following diagnostic interrupts (Page 47):
•
•
The detected error is indicated for the respective channel with feedback
bits (Page 38)Fault_Present and Sensor_Error.
Input of the number of steps (also micro steps) that correspond to one
revolution of the drive.
This parameter must match the "Increments per revolution" parameter in
the "Data exchange with encoder" tab of the axis technology object.

24 V, asymmetrical:
The channel outputs 24 V signals at terminals DQm.0 and DQm.1.
RS422, symmetrical / TTL (5 V), asymmetrical:
The channel outputs either RS422 signals at terminals P/A and D/B and
the respective inverted terminals or 5 V TTL signals at terminals P/A
and D/B.
