Homing to the stop
The stop is detected by a motor shutdown in combination with a sharp rise in the motor current and
expiration of the damping time. After that, the stop position must be abandoned through travel to the
axis zero point.
If the drive system does not have a stop (axis of rotation), homing will never be completed. The drive
then travels continuously at the parameterised search speed.
Note
If the EMCA continuously controls against a stop, the temperature rises sharply and the
EMCA shuts itself off.
Set parameters for stop detection (force limit, damping time).
Activate option “Travel from the homing point to the axis zero point”.
The axis zero point must be set in such a way that the axis does not run against the
stop/end-position cushioning in operation, even with overswinging (e.g. ≥ 3 mm).
A suitable value is preset at the factory. Do not change the presetting, if possible.
Pay attention to the direction specification (algebraic sign) of the offset (away from
the stop).
Note
Material damage due to shifted dimension reference system.
In the event of greatly reduced dynamic values (low maximum motor current) combined
with high travelling resistance (e.g. due to frictional grip), there is a danger that the
drive will come to a standstill and the controller will recognise a stop incorrectly.
Note
When homing to stop:
Protect delicate stops by reducing the search speed.
