Short Cam with Positive Limit
In the Short Cam with Positive Limit homing mode, the reference point is preset at the negative side of the cam, when coming in positive direction (off cam) at low velocity.
The Short Cam with Positive Limit homing mode uses the two homing-specific inputs:
Detected errors that can be encountered:
-
If the axis is already on the cam at start, the homing function will not be executed and the detected error is reported in the HOMING_FLT status object (%MWr.m.c.5.4).
-
When the axis is inside the working area (delimited by LimitSwitch signal) and direction is set backward (negative velocity), the homing function will not be executed and the detected error will be reported in the HOMING_FLT status object (%MWr.m.c.5.4).
-
If Drive_Ready&Emergency goes off (if not disabled and Drive_Enable output is active), the detected error is reported in the DRIVE_KO status object (%MWr.m.c.5.0).
The detected errors are also reported in the AXIS_FLT implicit status object (%IWr.m.c.6.3).
NOTE: During the homing process, the Proximity&LimitSwitch input will not be used as Limit Switch (no detection of limit crossing). For any other command, this input can still be used as Limit Switch input.
