ASDA-
BA: PR number (0 ~ 63)
DC: Masking range setting (0 ~ 95%)
YX: Range of filter (0 ~ 95%)
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 and the system will average the errors
before correction to avoid noise. If the error is bigger than filter threshold, the
system will use the new position to do the correction.
Function
Please note: Using filter will allow the alignment action to be more stable and
reduce position error caused by digital input noise.
UZ: Max. Max. allowable correction rate (0 ~ 100%)
When alignment correction is enabled, the limitation of max. correction rate (C)
for each correction is defined as follows:
Please note:
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 (0 ~ 63)
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.
Please note:
If BA is set to ０, it will not store the shortage of pulse numbers to PR.
DC: Masking range setting (0 ~ 95%)
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:
Please note:
This masking function only allows increasing pulse input. This function will
not work for decreasing pulse input.
