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 con-
tinue 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%.

MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START
(feed enable for spindle in setpoint range)
MD35100 $MA_SPIND_VELO_LIMIT
(maximum spindle speed)
NC/PLC interface signal DB390x DBX2001.5 (Spindle in setpoint range)
NC/PLC interface signal DB390x DBX2001.0 (Speed limit exceeded)
Alarm 22050 "Maximum speed reached"
Description: A limiting value for the maximum spindle speed is entered in MD35160
$MA_SPIND_EXTERN_VELO_LIMIT, which is taken into account exactly when the NC/
PLC interface signal DB380x DBX3.6 (Velocity/speed limitation) is set.
The control limits a spindle speed which is too high to this value.
