Effective acceleration profile (P-AXIS-00270)

P-AXIS-00270

Effective acceleration profile

Description

The parameter determines the effective acceleration profile. It is valid for:

  • Path axes during CNC-controlled homing
  • Spindle axes

Parameter

getriebe[i].slope_type

Data type

UNS16

Data range

0 ≤ slope_type ≤ 3 with:

0: Step-shaped acceleration profile

1: Trapezoidal acceleration profile

2: Sine-square acceleration profile

Axis types

T, R, S

Dimension

T: -

R,S: -

Default value

0

Drive types

----

Remarks

The following applies to contouring axes during reference point travel in all CNC versions:

Slope type:  Relevant dynamic characteristic values:

0           Linear Velocity Profile         getriebe[i].a_ref

1, 2       Non-linear velocity profile  getriebe[i].a_ref and getriebe[i].tr_ref

The following applies to spindle axes in CNC versions before V2.11.2800:

Slopetyp:    Relevant dynamic characteristic values:

0           Linear Velocity Profile          getriebe[i].lslope_profil.*

1, 2       Non-linear velocity profile   getriebe[i].slope_profil.*

As of CNC version V2.11.2800 or higher, the parameter for spindle axes has no more significance. The profile curve results from parametrising the dynamic characteristics in

     getriebe[i].slope_profil.*

For ramp times < CNC cycle time, this applies: Linear velocity profile

For ramp times ≥ CNC cycle time, this applies: Non-linear velocity profile
