YX: Range of filter (%)
When digital input, ALGN is triggered, E-Cam alignment function is
enabled. The system will detect the current E-Cam position. When
the error between current E-Cam position and the last alignment
position is less than this setting range (%), filter function is
enabled. Otherwise, the system will use the new position to do the
correction.
YX
Function
*Using filter will allow the alignment action to be more stable and
reduce position error caused by digital input noise.
UZ: Max. allowable correction rate (%)
When alignment correction is enabled, the limitation of max.
correction rate (C) for each correction is defined as follows:
| C | <= (P5-84/P5-83) x P2-73 UZ %
*When the alignment error is too big, to correct this error with one time
may cause the motor vibration or overloading. Using this parameter
will break the alignment correction into several smaller actions to
smooth the correction action. But it may need more time to finish the
alignment correction.
BA: PR number
After each alignment action is done, the shortage of pulse
numbers of slave axis will be stored in this specified PR. Using
this PR can compensate the slave position at appropriate timing.
*If BA is set to 0, it will not store the shortage of pulse numbers to
PR.
DC: Masking range setting (%)
When digital input, ALGN is triggered, no another alignment action
is allowed before the increasing pulse numbers of master axis
exceeds the masking distance (M). After the increasing pulse
numbers of master axis is greater than the distance (M) masking,
the next alignment action is allowed.
The masking distance (M) is defined as follows:
M >= (P5-84/P5-83) x P2-73 DC %
*This masking function only allows increasing pulse input. This function
will not work for decreasing pulse input.
