3 Simple Automation Alignment
YASKAWA TM.A1000SW.064 Electronic Line Shaft with Alignment A1000 Custom Software Supplement 27
The “In Alignment” digital output (H2-0 = 42) indicates whether the trigger inputs are activated within a settable
quadrature encoder count range. The In Alignment output energizes when the triggers are within the P4-07 setting and
will de-energize when the P4-07 setting is exceeded. This output will only change state after the trailing trigger has
activated.
„ Position Error Clear
A condition is added to this software that will clear the position error. When parameter P1-09 is set to 0 and High Slip
Braking is activated, the position error will be cleared.
