Commissioning
3.13 Commissioning of SIMOTICS L-1FN3 linear motors
Definition of the control sense
The control sense of an axis is correct if the positive direction of the drive (= clockwise
rotating field U, V, W) coincides with the positive counting direction of the measuring system.
If the positive direction of the drive and positive counting direction of the measuring system
do not match, then you must invert the actual speed value in the "Encoder configuration -
details" screen form when the drive is being commissioned (p0410.0 or p0410.1). See the
"Screen form for entering additional encoder data (Page 196)" figure.
Setting additional encoder data
1. If necessary, use "Encoder data" and "Details" to invert the actual speed and position
value.
This allows the control sense to be changed.
2. To do this, first click the "Encoder data" button in the screen form used for the encoder
configuration.
