9.2.57.2 Homing modes
The home position is defined via:
z the homing mode C0932
z the signal edge of the zero pulse or touch probe signal C0933
z the home position offset C0934
Tip!
If the position feedback is done via a resolver, the zero position applies instead of the zero pulse
(depending on the resolver connection to the motor). If referencing via touch probe, the touch probe
angle applies.
Referencing with reference switch to zero pulse/zero position
The home position is after the negative edge of the reference switch REF-MARK, at the next zero
pulse/zero position plus the home position offset:
z Mode 0 (C0932 = 0):
– Move to the home position in CW rotation.
– Select a positive home position offset C0934.
