Machine data
3.4 Axis-specific machine data
●
If an S value lower than the minimum speed is programmed, the setpoint speed is
increased to the minimum speed.
●
The NC/PLC interface signal "Setpoint speed increased" is set to indicate that the
speed has been increased.
●
The minimum speed entered here has no effect on the automatic gear stage selection
M40 S..
●
The lower switching threshold for the automatic gear stage selectionM40 is
configured in MD35120 $MA_GEAR_STEP_MIN_VELO.
Not relevant for:
●
Spindle oscillation mode(gear stage change)
●
Positioning and axis spindle modes
●
Signals which cause the spindle to stop
Related to:
MD35130 $MA_GEAR_STEP_MAX_VELO_LIMIT (maximum speed of gear stage with speed control)
MD35135 $MA_GEAR_STEP_PC_MAX_VELO_LIMIT (maximum speed of gear stage with position
control)
MD35010 $MA_GEAR_STEP_CHANGE_ENABLE (gear stage change is possible)
MD35110 $MA_GEAR_STEP_MAX_VELO (max. speed for automatic gear stage selection M40)
MD35120 $MA_GEAR_STEP_MIN_VELO (min. speed for automatic gear stage selection M40)
35150 SPIND_DES_VELO_TOL
- Spindle speed tolerance
-
- -
Description:
In spindle control mode, the set speed (programmed speed x spindle offset, allowing
for limits) is compared with the actual speed.
●
If the actual speed deviates from the set speed by more than MD35150
$MA_SPIND_DES_VELO_TOL, the NC/PLC interface signal is DB390x DBX2001.5 (Spindle in
setpoint range) is set to zero.
●
If the actual speed deviates from the set speed by more than MD35150
$MA_SPIND_DES_VELO_TOL, the path feed is disabled (positioning axes continue
traversing).
●
If the actual speed exceeds the maximum spindle speed (MD35100
$MA_SPIND_VELO_LIMIT) by more than MD35150 $MA_SPIND_DES_VELO_TOL, the NC/PLC
interface signal is DB390x DBX2001.0 (Speed limit exceeded) is enabled and alarm
22050 "Maximum speed reached" is output. All axes and spindles on the channel are
decelerated.
MD irrelevant to:
●
Spindle oscillation mode
●
Spindle positioning mode
Example:
MD 35150 $MA_SPIND_DES_VELO_TOL = 0.1
The actual spindle speed must not deviate from the set speed by more than +/- 10%.
