Homing methods -9 and -10:
These methods are used to move to a mechanical stop and finally referenced to the en-
coder zero angle or zero pulse.
With Mode –9 the drive moves clockwise and with –10 counterclockwise toward the me-
chanical stop.

During homing runs to a mechanical stop, specific monitoring procedures may trigger a
error due to the mechanical blocking. This includes the position error monitoring, moni-
toring of speed difference and block monitoring.

Mode bit 5 will prompt the controller to deactivate the three mon-

3.8.3.19 Command set home position
Besides the homing it is possible to set the reference point in the inhibited state (pulse
inhibit). By writing the command "Set reference point" to the parameter

the set
value of the reference point is taken over at the current position.
The drive acknowledges the setting of the reference point by setting the bit 2 in the pa-
rameter Homing status

. By writing the command value 0 the bit 2 in the homing
status is reset again.
However the command is possible in the inhibited state only independent of the current
operation mode of the drive.
3.8.3.20 Parameter overview
Functional block: FbHoming [120]
CAUTION!
1 The controller cannot distinguish with homing methods –7, -8, -9 and –10 whether
the block is caused by the mechanical stop or otherwise! In the second case, the
drive is incorrectly referenced!
2 The machine may be damaged with homing methods against mechanical stops.
The user must prevent this through a sufficiently low setting of the homing speed
(
Z

) and the maximum drive torque during homing (
Z
120.12
–
).
