Subroutine 49 - GearChg1_Auto (automatic spindle gear change)

Purpose
Subroutine 49 is used to automatically change the gear for the analog spindle with 2-level gear detection signals.
During a gear change, the spindle oscillates and the PLC outputs the gear change signal. When the PLC detects that the
desired gear level has been reached, the gear change has been completed.
You cannot use this subroutine together with subroutine 50.
