S1: Spindles
16.2 Operating modes
Feed
The positioning speed is configured in the machine data:
MD35300 $MA_SPIND_POSCTRL_VELO (position control switching speed)
The configured positioning speed can be modified by programming or by synchronized actions:
FA[S<n>]=<value>
wher Spindle number
<n>:
e:
Positioning speed in degrees/min
<value
>:
With FA[S<n>]=0, the configured speed takes effect.
Acceleration
The accelerations are configured in the machine data:
MD35210 $MA_GEAR_STEP_POSCTRL_ACCEL(acceleration in position control mode)
MD35200 $MA_GEAR_STEP_SPEEDCTRL_ACCEL(Acceleration in the speed control mode)
The configured dynamic response during positioning can be modified by programming or by synchronized
actions:
ACC[S<n>]=<value>
wher Spindle number
<n>:
e:
Acceleration as a percentage of the configured acceleration
<value
>:
With ACC[S<n>]=0, the configured acceleration takes effect.
Aborting the positioning process
The positioning action is aborted:
• By the NC/PLC interface signal:
DB31, ... DBX2.2 (delete distance to go / spindle reset)
• With every reset (e.g. operator panel front reset)
• by NC-STOP.
The abort response in independent of the machine data:
MD35040 $MA_SPIND_ACTIVE_AFTER_RESET (individual spindle reset)
Special features
The spindle override switch is active.
