When the master axis resumes operation, use another PR for the moving distance of the return trip
(-Y_Drift) to return to the original position (moving distance of onward trip + moving distance of
return trip = 0) . E-Cam position remains the same.
When E-Cam rotates one cycle,
pulse number of master axis: (P5.084 / P5.083)

Moving distance

Note: regardless of onward trip or return trip, use the PR command through incremental positioning control.
Due to cyclic operation, when E-Cam moves from current position to the target position, it can either
rotate in the forward or reverse direction. However, the moving distance is usually different between
them. Thus, you can use the allowable forward rate to determine whether to operate in forward or
reverse rotation.
* Allowable forward rate: the allowable maximum proportion of forward path . Please see below for
details.
E-Cam current position
Max. forward rotation limit. Counterclockwise is
forward direction in the figure
Target position is within the range; onward trip
is in forward direction

is in reverse direction

Failure code F0F1h When executing this macro command, E-Cam is not in engaged status.
Engaged position can only be modified when E-Cam is engaged.
Failure code F0F2h P5.093.YX (PR number of onward trip) exceeds the range: 0 – 0x3F
Failure code F0F3h P5.093.UZ (PR number of return trip) exceeds the range: 0 – 0x3F
Failure code F0F5h P5.095 (allowable forward rate) exceeds the range: 0 – 100 (%)
Failure code F0F6h P5.096 (target position) exceeds the range: 0 to (P5.084/P5.083) - 1
