10.3.4 Establish the absolute origin coordinates
When the absolute coordinates are lost, the ASDA-B3 servo drive provides three ways to
establish the absolute origin coordinates: DI/DO, parameter setting, or the PR homing function.
The following provides more details for each operation mode.
10.3.4.1 Establishing the absolute origin coordinates with DI/DO
When the servo system is controlled by the controller, you can reset the absolute coordinate
system with DI/DO. Once established, the pulse number is set to 0 and the PUU number is the
value of P6.001. Refer to the following diagram for detailed descriptions.
Description:
1. When the controller triggers DI.ABSE (rising-edge triggered), it needs to wait for T
S
before
proceeding to the next step.
2. After reaching T
S
, the controller starts to reset the coordinate system. When DI.ABSC turns
on and remains on for T
Q
the pulse number is set to zero and the PUU number is set to the
value of P6.001.
