Operating Modes
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.

m Phase 2
During homings to a mechanical stop, specific monitoring procedures may trigger a error
due to the mechanical blocking. This includes the position error monitoring, monitoring of
speed difference and block monitoring.
Activating the
itoring procedures for the period of homing, which means from the start of homing to the
recognition of the mechanical stop after expiration of the
time.

4.8.3.19 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
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 Z120.1–. 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.

When the mechanical stop is recognized, the torque limit
limit is canceled again and referenced in the reverse direction of travel with
Homing final speed to the encoder zero angle or zero pulse.

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!
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
(Z120.5–) and the maximum drive torque during homing (Z120.12–).
