Stick-slip friction
compensation
(MP_compFriction0,
MP_compFrictionT1,
MP_compFrictionT2)
Same as CC 424 Feed-rate independent;
MP_compFriction0 same
meaning as previously (effective
values, readjustment
necessary),
MP_compFrictionT1 new
meaning
MP_compFrictionT2 new
Filter in the speed control
loop
Same as CC 424 MP_vCtrlFiltLowPassT omitted,
new machine parameters:
MP_vCtrlFiltDamping1 to
MP_vCtrlFiltDamping5
MP_vCtrlFiltFreq1 to
MP_vCtrlFiltFreq5
MP_vCtrlFiltType1 to
MP_vCtrlFiltType5
MP_vCtrlFiltBandWidth1 to
MP_vCtrlFiltBandWidth5
MP_vCtrlEncInputFilt new
meaning
Master-slave torque control The PWM outputs of the master and
slave axes must always be operated
on the same DSP (meaning the
same controller basic board for the
CC 61xx), i.e. the master and slave
axes must be operated with the
same power.
More slave axes are possible for the
CC 61xx than before, e.g. up to five
slave axes are possible for a CC for
six axes.
The PWM outputs of the master
and slave axes must always be
operated on the same DSP
("single-speed" setting)
Reading the absolute value
of encoders with EnDat
interface
Same as CC 424 The absolute value can be read
out again via the PASS OVER
REFERENCE soft key or via Module
9220 (i.e. after the exchange of
milling heads).
MP_motEncCheckOff Same as CC 424 Bit 4: Monitoring for excessive
temperature
Bit 5: Monitoring for insufficient
temperature
Bit 6: Reserved
Bit 7: Monitoring of encoder
input frequency
Bit 8: Adjust mechanical offset
by gradually increasing the k
V
factor
MP_motTypeOfFieldAdjust Same as CC 424 Determining the field angle for
unaligned encoders
MP_plcCount Same as CC 424 PLC cycle time [ms]
Function CC 61xx CC 424
