2.6.3 Spindle in setpoint range
Function
"Spindle in setpoint range" spindle monitoring checks whether:
• The programmed spindle speed is reached.
• The spindle is stationary (NC/PLC IS:
DB31, ... DBX61.4 (axis/spindle stationary)).
• The spindle is still in the acceleration or deceleration phase.
In spindle control mode, the setpoint speed
(programmed speed ∗ spindle offset including active limitations)
is compared with the actual speed.
If the actual speed deviates from machine data:
MD35150 $MA_SPIND_DES_VELO_TOL
by more than the spindle speed tolerance:
• Axial NC/PLC IS:
DB31, ... DBX83.5 (Spindle in setpoint range)
is set to 0.
• The next machining block is not enabled.
• Machine data:
MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START
is set to 1.
Exception:
MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START = 0
Path interpolation is not influenced, the traveled path axis is not stopped.
