• Homing mode 1:
(like homing mode 0, but negative traversing direction)
TIP!
Instead of the zero pulse for the feedback system, it is also possible to define a touch probe
signal as the signal for the homing, derived from digital input E4 (however, this is not
common in mode 0 and 1).
Homing mode 8:
The drive rotates in the positive direction (clockwise rotation) until a zero pulse from the
motor feedback system is detected or a touch probe signal is detected on the related digital
input. This signal defines the home position (machine zero point).
If the home position does not represent the zero point of the absolute measuring system
used, the home position can be defined in relation to the zero point for the measuring system
using an offset (machine zero distance, C3227/000). After the homing has been completed,
the drive stays on the position 0.0000[units]:
In the example shown above, the home position represents a positive value in relation to the
measuring system zero point, because after the acquisition of the zero pulse/touch probe
signal the drive reverses and moves back to the measuring system zero position
(0.0000[units]).
• Homing mode 9:
(like homing mode 8, but negative traversing direction)
TIP!
Instead of the touch probe signal from digital input E4, it is also possible to define the zero
pulse for the feedback system as the signal for defining the homing (however this is not
common in modes 8 and 9).
