Programming and Operating Manual (Turning)

There is no difference between DC and AC dimensioning. In both cases, rotation continues in the direction selected by M3/M4
until the absolute end position is reached. With
ACN and ACP, deceleration takes place if necessary, and the appropriate
approach direction is taken. With
IC, the spindle rotates additionally to the specified value starting at the current spindle
position.
Position a spindle from standstill (M5)
The exact programmed distance is traversed from standstill (M5).
Gear stages
Functionality
Up to 5 gear stages can be configured for a spindle for speed / torque adaptation.
The relevant gear stage is selected in the program via M commands:
; Automatic gear stage selection

Constant cutting rate: G96, G97
Functionality
Requirement:
A controlled spindle must be present.
With activated G96 function, the spindle speed is adapted to the currently machined workpiece diameter (transverse axis)
such that a programmed cutting rate S remains constant on the tool edge:
Spindle speed times diameter = constant.
The S word is evaluated as the cutting rate as of the block with G96. G96 is modally effective until cancellation by another G
function of the group (G94, G95, G97).
; Constant cutting speed ON
; Constant cutting speed OFF
; Cutting rate, unit of measurement m/min.
; Upper limit speed of the spindle with G96, G97 effective
; Feedrate in mm/revolution - as for G95
