Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Transition to axis mode
Transition to axis mode by programming:
•
The spindle with its own identifier or by M70 and by means of the
M
function:
MD20094 $MC_SPIND_RIGID_TAPPING_M_NR
•
The relevant machine data when changing the servo parameter set are:
MD31050 $MA_DRIVE_AX_RATIO_DENOM
(Measuring gear denominator)
MD31060 $MA_DRIVE_AX_RATIO_NUMERA
(Numerator load gear unit)
MD32200 $MA_POSCTRL_GAIN
(Servo gain factor (Kv))
MD32452 $MA_BACKLASH_FACTOR
(Weighting factor for backlash)
MD32610 $MA_VELO_FFW_WEIGHT
(Weighting factor for feedforward control)
MD32800 $MA_EQUIV_CURRCTRL_TIME
(Equivalent time constant current control circuit
for feedforward control)
MD32810 $MA_EQUIV_SPEEDCTRL_TIME
(Equivalent time constant speed control loop for
feedforward control)
MD32910 $MA_DYN_MATCH_TIME
(Time constant for dynamic matching)
MD36012 $MA_STOP_LIMIT_FACTOR
(Factor for exact stop coarse/fine and zero speed
control)
MD36200 $MA_AX_VELO_LIMIT
(Threshold value for velocity monitoring)
•
The dynamic limits of the axis stored in the machine data are applicable in axis operation.
•
The axis switches to the current feedforward control mode as designated by the MD and
the commands
FFWON
and
FFWOF
.

When using resolution changes in (analog) drive actuators, the following NC program
steps are required:
