Y-Axis Instead of XC or ZC -- Some machines support a Y-axis stroke instead of the combined ZC or XC output. In this case, the command MODE/YAXIS,ON-OFF-AUTO is supplied to be used in the input program. When Auto is selected, make sure that the Y-axis limits is set. The GPost will automatically select Y machine or XC and ZC when programmed Y-axis is within the set limits. (Intcom 4619)
