There are two reference travel speeds. The higher search velocity (
speed_during_search_
for_switch
) is used to find the limit switch or the reference switch. Then, to exactly
determine the position of the switch edge, the system switches to crawl speed
(
speed_during_search_for_zero
).
If the drive should not be newly referenced but only the position set to a specified value,
the object
2030
h
(
set_position_absolute
) can be used.
: set_position_absolute on page 97.
The drive to the zero position under CANopen is normally not a
component of the reference travel. If all necessary variables are
know to the motor controller (e.g. because it already knows the
position of the zero pulse), no physical movement is performed.
This behaviour can be changed via the object
6510
h
_ F0
h
(
compatibility_control
see chapter 6.2), so that a run to zero is
always carried out.
