1. AXIS CONTROL
211
S To apply mirror–image synchronization (because initially the
positive direction of one axis is opposite to that of the other axis),
set SMRz (bit 0 of parameter No. 8162) of path 2 to “1”.
S To detect out–of–synchronization (because both axes should move
by the same amount), set SERz (bit 1 of parameter No. 8162) to “1”.
Set a value from 100 to 1000 as a limit to out–of–synchronization
in parameter No. 8181z of path 2 (this limit varies from one
machine to another).
S A difference in the positional deviation between the Z1– and
Z2–axes is indicated in parameter No. 8182z during
synchronization.
(3)Signal operation
S Set signal G1138#1 SYNC2 to “1” when the Z1– and Z2–axes start
moving in synchronization.
S Reset signal G1138#1 SYNC2 to “0” when synchronization is
terminated.
S Also reset signal G1138#1 SYNC2 to “0” if an emergency stop, NC
reset, or alarm occurs.
S Keep signals other than G1138#1 SYNC2 reset to “0”.
