Mode 15: <_Mlim
Procedure:
1. Movement in a negative direction with reduced torque and start profile data set.
2. The reference is set if it is detected that the torque limit set in C01222
is exceeded beyond the
time set in C01223
("Homing to positive stop").
• If a home value offset has not been set, this position is the home position.
• If a home value offset has been set, correctly signed traversing by this offset takes place and
the home position is set at the end of this travel distance.
 Tip!
Set a home value offset in C01227/1
to avoid stopping at the positive stop.
Mode 100: SetRef
When the drive is at standstill, the measuring system is set via the bit 8 ("HomStartStop") in MCK
control word. The current actual position now corresponds to the home position set in C01227/2 in
the machine measuring system.
