The machine data included in a parameter set are marked specifically in Section "Machine data (Page 170)". The following
machine data is added per gear stage for each parameter set index n (n=1 -> 1st gear stage of the spindle, etc.):
● MD35110 GEAR_STEP_MAX_VELO[n]
● MD35120 GEAR_STEP_MIN_VELO[n]
● MD35130 GEAR_STEP_MAX_VELO_LIMIT[n]
● MD35140 GEAR_STEP_MIN_VELO_LIMIT[n]
● MD35200 GEAR_STEP_SPEEDCTRL_ACCEL[n]
● MD35210 GEAR_STEP_POSCTRL_ACCEL[n]
● MD35310 SPIND_POSIT_DELAY_TIME[n]
The spindle can be set for the following functions:
● G95 Revolutional feedrate
● G96 S... LIMS=... Constant cutting rate in m/min, upper speed limit
● G97 Cancel G96 and freeze last spindle speed
● G33, G331, G332 Thread cutting, tapping
● G4 S ... Dwell time in spindle revolutions
Spindle stop, without orientation
Spindle speed in rpm, e.g. S300
Spindle positioning, e.g. SPOS=270
-> at position 270 degrees.
The block change is only performed when the spindle is in position.
The direction of motion is retained for positioning while in motion and the position a
pproached.
When positioning from standstill, the position is approached via the shortest path.
The position is always approached with negative direction of motion. If necessary, the direction of
motion is inverted prior to positioning.
The position is always approached with positive direction of motion. If necessary, the direction of
motion is inverted prior to positioning.
The traversing path is specified. The direction of traversing is obtained from the sign in front of
the tr
aversing path. If the spindle is in motion, the direction of traversing is inverted if necessary
to allow traversing in the programmed direction.
Automatic gear stage selection for the spindle
Select gear stage 1 to 5 for the spindle
Programmable maximum spindle speed for G96
