Velocity
The positioning velocity is taken from the machine data:
MD35300 $MA_SPIND_POSCTRL_VELO
NC/PLC IS "Spindle speed override"/"Feedrate override" at
DB31, ... DBX17.0=0: DB31, ... DBB19)
as well as:
DB31, ... DBX17.0=1: DB31, ... DBB0
are effective as normal for positioning.
The positioning speed can be changed proportionally through the program instruction
OVRA[Sn
].
Note
OVRA[Sn]
is valid modally. After the gear step change, a value appropriate for the
machining should be reset.
The part-program instruction
FA[Sn]
does not change the positioning speed during gear
step change.
acceleration
The acceleration values are determined through the gear step dependent machine data:
MD35200 $MA_GEAR_STEP_SPEEDCTRL_ACCEL
and
MD35210 $MA_GEAR_STEP_POSCTRL_ACCEL
.
The acceleration can be changed proportionally by programming
ACC[Sn]
.
Note
ACC[Sn]
is valid modally. After the gear step change, a value appropriate for the machining
should be reset.
Speed-dependent acceleration
The "kneeshaped acceleration characteristic" is effective as in positioning with
SPOS
or
FC18.
Jerk
It is currently not possible to limit the change in acceleration.
