Siemens SINUMERIK 808D Function Manual

Function Manual

● Program execution is terminated.
● Alarm 10720 "Software limit switch + or -" is signaled.
JOG:
● The axis stops at the software limit switch position.
● Alarm 10621 "Axis at software limit switch + or -" is signaled.
● The direction keys in the approach direction are disabled.
Note
Switching over the software limit switch:
If the current position lies behind the new software limit switch when the software limit switch is switched over, the
axis is
decelerated with the maximum permissible axial acceleration. If an axis is involved in interpolation with other axes, these are
also decelerated. Then a contour violation may occur.
Remedy
● Reset
● Move in the opposite direction (in "JOG" mode)
● Correct the program

Supplementary conditions
To ensure that the monitoring functions respond correctly, it is important that the correct values are entered in the following
machine data:
General:
● MD31030 LEADSCREW_PITCH (leadscrew pitch)
● Gear ratio (load gearbox):
MD31050 DRIVE_AX_RATIO_DENOM (load gearbox denominator)
MD31060 DRIVE_AX_RATIO_NUMERA (load gearbox numerator)
Gear ratio (encoder), possibly for spindle:
MD31070 DRIVE_ENC_RATIO_DENOM (measuring gearbox denominator)
MD31080 DRIVE_ENC_RATIO_NUMERA (measuring gearbox numerator)
● MD32810 EQUIV_SPEEDCTRL_TIME
(Equivalent time constant speed control loop for feedforward control)
● Encoder resolution
MD31020 ENC_RESOL[0] (encoder pulses per revolution)
For analog spindle only:
● Output voltage / output speed relation
MD32260 RATED_VELO (rated motor speed)
MD32250 RATED_OUTVAL (rated output voltage)
