Description

P-AXIS-00568

Damping factor of natural frequency

Description

Besides the natural frequency itself, this parameter can also specify the damping factor of the natural frequency which is defined as follows:

Parameter

vib_guard.damping

Data type

REAL64

Data range

0 ≤ damping ≤ 1

Axis types

T, R, S

Dimension

T: ----

R,S: ----

Default value

0.1

Drive types

----

Remarks

The parameter is available as of V3.1.3075.00

P-AXIS-00571

Vibration Guard mode

Description

This parameter defines Modes 1 - 4 of the Vibration Guard function.

 

Modes 1– 3:

  • Asymmetrical modes (contours may have different forward and backward motions).
  • The higher the mode (1-3), the less sensitive to deviations from the actual natural frequency
  • The higher the mode (1-3), the larger the axis error (or contour deviation)

Mode 4:

  • Symmetrical mode (contours are identical in forward and backward motion).

 

Parameter

vib_guard.mode

Data type

UNS32

Data range

1 ≤ mode ≤ 4

Axis types

T, R, S

Dimension

T: ----

R,S: ----

Default value

1

Activating the Vibration Guard

Description

This parameter can permanently activate or deactivate the Vibration Guard function at program start.

Parameter

vib_guard.active

Data type

BOOLEAN

Data range

0/1

Axis types

T, R, S

Dimension

T: ----

R,S: ----

Default value

0

Drive types

----

Remarks

Alternatively, the Vibration Guard can also be activated or deactivated by the NC command #VIB GUARD / OFF .

P-AXIS-00589

Machine natural frequency

Description

This parameter specifies the machine’s natural frequency which the Vibration Guard function is to suppress.

Parameter

vib_guard.freq

Data type

REAL64

Data range

1 ≤ freq

Axis types

T, R, S

Dimension

T: Hz

R,S: Hz

Default value

30
