Backlash compensation with an additional command pulse.
BAKANOUT
Additional velocity command pulse.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drives and Sercos drives.
Possible values: Within ±32767 with an analog drive / within ±1000 rpm with a Sercos drive.
Default value: 0 (Not applied).
Associated variable: (V.)[ch].MPA.BAKANOUT[set].xn
Additional velocity command pulse to make up for the possible leadscrew backlash when
reversing the moving direction. Every time the movement is inverted, the CNC will apply to
that axis the velocity command corresponding to the movement plus the additional velocity
command pulse set in this parameter. The duration of this additional velocity command
depends on parameters BAKTIME and PEAKDISP.
With an analog drive, the additional velocity command is given in units of the D/A converter
with an integer within ± 32767. - 10 V for a value of -32767 and +10V for a value of 32767.
On analog axes, when LOOPCH=Yes, BAKANOUT must be set with a negative value so
the CNC applies the right reversal peak for movement reversal.
When setting an additional command pulse, parameters BAKTIME, ACTBAKAN and
PEAKDISP must also be set.
BAKTIME
Duration of the additional velocity command pulse.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drives and Sercos drives.
Possible values: From 0 to 100 ms.
Default value: 0.
Associated variable: (V.)[ch].MPA.BAKTIME[set].xn
The CNC only takes this parameter into consideration when working with an additional
velocity command pulse; BAKANOUT other than zero. Parameter BAKTIME indicates the
duration of the additional velocity command pulse to make up for backlash in movement
reversals.
ACTBAKAN
Application of the additional velocity command pulse.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drives and Sercos drives.
Possible values: Always / G2-G3.
Default value: Always.
Associated variable: (V.)[ch].MPA.ACTBAKAN[set].xn
The CNC only takes this parameter into consideration when working with an additional
velocity command pulse; BAKANOUT other than zero. Parameter ACTBAKAN determines
when the additional command pulse is applied to compensate for backlash peaks.
