Set an end distance for inner corner override in automatic corner overriding.

When θ ≤ θp, an inner corner is assumed. (Parameter No. 1711 is used to set θp.)

When a corner is determined to be an inner corner, an override is applied to the feedrate

in the range of Le in the previous block from the intersection of the corner and in the

range of Ls in the next block from the intersection of the corner.

Distances Le and Ls represent linear distances from the intersection of a corner to points

on the tool center path.

Le and Ls are set in parameter No. 1713 and No. 1714.

Rapid traverse feedrate reduction ratio for overlapping rapid traverse blocks

[Input type] Parameter input

[Data type] Byte axis

[Unit of data] %

[Valid data range] 0 to 100

This parameter is used when rapid traverse blocks are arranged successively, or when a

rapid traverse block is followed by a block that does not cause, movement. When the

feedrate for each axis of a block is reduced to the ratio set in this parameter, the execution

of the next block is started.

Feedrate is controlled so that acceleration produced by changing the move direction in

circular interpolation does not exceed the value specified in this parameter.

AI advanced preview control, or AI contour control, not the ordinary time constant

4.DESCRIPTION OF PARAMETERS

If a feedrate component change for each axis exceeding the value set in this parameter

occurs at the joint of blocks, the feedrate determination function based on corner feedrate

difference finds a feedrate not exceeding the set value and performs deceleration by using

acceleration/deceleration before interpolation. Thus, a shock to the machine and

machining error at a corner can be reduced.

Maximum allowable acceleration change rate in feedrate determination based on acceleration change

for each axis

[Input type] Parameter input

[Data type] Real axis

[Unit of data] mm/sec², inch/sec², degree/sec² (machine unit)

is inch system, machine, 0.0 to +10000.0.)

[Min. unit of data] Depend on the increment system of the applied axis

[Valid data range] Refer to the standard parameter setting table (D)

(When the machine system is metric system, 0.0 to +100000.0. When the machine system

is inch system, machine, 0.0 to +10000.0.)

Set a maximum allowable acceleration change rate for each axis in feedrate control based

on acceleration change under control on the rate of change of acceleration in successive

linear interpolation operations.

In feedrate control based on acceleration change at a corner between linear interpolation

operations, the maximum allowable acceleration change rate not set in parameter

No.1788 but set in this parameter is valid.

For an axis with 0 set in this parameter, the maximum allowable acceleration change rate

set in parameter No.1788 is valid.

Feedrate control based on acceleration change is disabled for an axis with 0 set in

parameter No.1788, so that the setting of this parameter for such an axis is ignored.
