Retrigger Reference Point
Definition
With the “retrigger reference point” setting, you can synchronize the axis as result
of recurrent external event.
The setting remains active until you switch it off again.
Requirements
•
You are using an incremental encoder or initiator.
•
The external event can be a zero marker of an incremental encoder or a
reference point switch at input I2.
Sequence of a Setting
1. Enter the value for the reference point coordinate in the parameter DB.
2. Enter the type of “retrigger reference point” in the parameter DB.
Here, you have the following options:
•
Only the zero marker of the encoder is evaluated (RETR_TYPE = 7).
•
Only the reference point switch is evaluated (RETR_TYPE = 6).
•
The zero marker is evaluated
– in the positive direction: the first rising edge of the zero marker after
leaving the reference point switch in a positive direction is evaluated
(RETR_TYPE = 0).
– in negative direction: the first falling edge of the zero marker after leaving
the reference point switch in a negative direction is evaluated
(RETR_TYPE = 1).
3. Write and activate the machine data.
4. Set the function switch in the channel DB.
