Slaveoff> function block operation notes – Yaskawa MP2000 User Manual
Page 100
TECHNICAL NOTE
• Rising edge of EXECUTE input initiates block operation, and all block input
values are read once.
• To use the function block, the EXECUTE bit must be held ON. If the EXECUTE
bit goes off during operation, the block will stop executing (will not complete the
change), the offset up to that point will remain, and all outputs will be set to zero.
• The
RUNNING
output bit will be held high until the Offset move is completed,
EXECUTE
goes low, or an Error occurs.
• The
DST-TIME
bit must be set to TRUE to use the master position change or
FALSE for the time duration.
• Distance mode note: Be sure to set the duration in the same direction as the
master movement. Example: If the block is in Distance mode and the master is
moving in the negative direction, and the DURATION is set positive, it will
subtract the relative offset and hence the resulting offset will not complete. As a
result, the DONE output will not go on because the full move is not complete in
the correct direction.
• The value <'of block in execution (Block Running)> is indicated in master/slave
pair part RDA(MW56**6).
• Issuing a STOP block on the slave axis will have no affect on the OFFSET block
execution.
• Note that the master/slave pairs are separated by 50 words in the RDA (up to 10
pairs). Example: Master/Slave pair #1 starts at MW56000, Master/Slave pair #2
starts at MW56050, Master/Slave pair #3 starts at MW56100, etc.
• Twenty-three words are used as working registers for this function, starting at the
address in Data23W.
