A.2.2 Reference travel
With electric mini slide SLTE, reference travel must be carried
out when the device is switched on as prerequisiite for a posiĆ
tioning task (Bit Drive_is_referenced = TRUE).
The drive references against a stop or a reference switch. An
increase in the motor current indicates that a stop has been
reached. As the drive must not continuously reference
against the stop, it must move at least one millimetre back
into the stroke range.
Sequence:
1. Search for the reference point in accordance with the
configured method.
2. Move relative to the reference point around the
Offset axis zero point".
3. Set at axis zero point:
Current position = 0 + offset project zero point.
