Notice
A maxium of 5 spindle gear stages can be provided. Assigning the same
parameters to the index [0] and [1] makes gear changes (i=1 ... 5) active only
by setting corresponding interface signals via PLC application.
Programming notice
Pay attention to the following instructions when programming machining
programs:
1) When mm/Min is used as the unit of measurement for the feedrate F,
activate G94; Programming example: N10 G94 G01 Z100 F100
2) When mm/Rev is used as the unit of measurement for the feedrate F,
activate G95; mm/Rev. Programming example: N10 G95 G01 Z100 F1
3) For contactor-controlled spindle, when producing a thread with G33,
program spindle speed S within the actual spindle speed range;
4) When programming a thread cutting, program thread run-in and run-out
paths;
5) The result of a thread lead value multiplied by spindle speed shall be
less than the maximum setpoint speed of Z axis.
