10.5.21 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. See
above, Subsection 10.5.4, page 10-315.
10.5.22 Gear stages
The gear stage change is generally carried out in
MD35010: GEAR_STEP_CHANGE_ENABLE (gear stage change possible),
spindle has several gear stages).
If this machine data is not set, the system assumes that the spindle has no gear
stages.
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: GEAR_STEP_MAX_VELO[n] (n
max
for gear stage change)
MD35120: GEAR_STEP_MIN_VELO[n] (n
min
for gear stage change)
MD35130: GEAR_STEP_MAX_VELO_LIMIT[n] (n
max
for gear stage)
MD35140: GEAR_STEP_MIN_VELO_LIMIT[n] (n
min
for gear stage)
MD35200: GEAR_STEP_SPEEDCTRL_ACCEL[n]
(acceleration in speed-control mode)
MD35210: GEAR_STEP_POSCTRL_ACCEL[n] (acceleration in position
control mode).
