Machine data
2.4 Axis-specific machine data
Description: MD35100 $MA_SPIND_VELO_LIMIT defines the maximum spindle speed that the spin-
dle (the spindle chuck with the workpiece or the tool) must not exceed. The
NCK limits an excessive spindle setpoint speed to this value. If the maximum
spindle actual speed is exceeded, even allowing for the spindle speed toler-
ance (MD35150 $MA_SPIND_DES_VELO_TOL), there is a fault with the drive and
the NC/PLC interface signal DB390x DBX2001.0 (speed limit exceeded) is set.
Alarm 22100 "Maximum speed reached" is also output and all axes and spindles
on the channel are decelerated (provided the encoder is still functioning
correctly). The spindle has to be brought to a standstill before modifying
the MD.
Corresponds with:
MD35150 $MA_SPIND_DES_VELO_TOL (spindle speed tolerance)
SD43235 $SD_SPIND_USER_VELO_LIMIT (speed limitation set by user)
NC/PLC interface signal DB390x DBX2001.0 (speed limit exceeded)
Alarm 22100 "Maximum speed reached"
Description: MD35110 $MA_GEAR_STEP_MAX_VELO defines the maximum speed (upper switching
threshold) of the gear stage for automatic gear stage change M40 S... The
speed ranges for the gear stages must be defined without gaps between them or
can overlap.
Incorrect
MD35110 $MA_GEAR_STEP_MAX_VELO [gear stage1] =1000
MD35120 $MA_GEAR_STEP_MIN_VELO [gear stage2] =1200
Correct
MD35110 $MA_GEAR_STEP_MAX_VELO [gear stage1] =1000
MD35120 $MA_GEAR_STEP_MIN_VELO [gear stage2] = 950
Note:
• Programming a spindle speed which exceeds the highest numbered gear stage
MD35110 $MA_GEAR_STEP_MAX_VELO [MD35090] triggers a switch to the highest
gear stage (MD35090).
