Setpoint/Actual Value Channels Of Spindle; Gear Stages - Siemens SINUMERIK 840Di sl Commissioning Manual

NC Commissioning with HMI Advanced
11.5 Axes and spindles
Spindle reset
The following machine data is used to define whether the spindle should remain active via
Reset (IS DB21,... DBX7.7) or Program end (M02/M30) even subsequently:
● MD35040 $MA_SPIND_ACTIVE_AFTER_RESET (spindle active after reset)
To cancel spindle movements, an independent spindle reset is required:
● IS DB31,... DBX2.2 (spindle reset)

Setpoint/actual value channels of spindle

Parameterization of the setpoint/actual value channels of a spindle is identical to
parameterization of the setpoint and actual value channels of an axis. For this, see
Subsection "Setpoint value/actual value channels" (Page 393).
11.5.22

Gear stages

Initiation of gear change
The gear stage change is generally carried out in the following machine data:
● MD35010 $MA_GEAR_STEP_CHANGE_ENABLE (gear stage change possible, spindle
If this machine data is not set, the system assumes that the spindle has no gear stages.
Parameter sets
In spindle mode of a spindle, the NC will select the parameter set that suits the current gear
stage best.
Gear stage x => parameter set (x+1) => index [x]
In axis mode of a spindle, the NC always selects the 1st parameter set (index [0],
independent of the current gear stage.
The machine data listed in the following are gear stage-dependent machine data of a spindle:
● MD35110 $MA_GEAR_STEP_MAX_VELO[n] (n
● MD35120 $MA_GEAR_STEP_MIN_VELO[n] (n
● MD35130 $MA_GEAR_STEP_MAX_VELO_LIMIT[n] (n
● MD35140 $MA_GEAR_STEP_MIN_VELO_LIMIT[n] (n
● MD35200 $MA_GEAR_STEP_SPEEDCTRL_ACCEL[n] (acceleration in speed-control
● MD35210 $MA_GEAR_STEP_POSCTRL_ACCEL[n] (acceleration in position control
