Parameter
15550 Approach-completion-sensing band width (A
PRCH
)
[Data type] Word
[Unit of data] 0.001mm
[Valid data range] 0 to 32767
[Standard setting value] 50
Set the amount of shift used to assume approach completion.
Approach completion is assumed when the state where the amount of
shift is within a specified approach-completion-sensing bandwidth has
existed for the approach completion interval, set in parameter No.
15551, or longer.
15551 Approach completion interval time
[Data type] Word
[Unit of data] msec
[Valid data range] 0 to 32767
[Standard setting value] 500
Upon detecting the state where the tracing shift is within the
approach-completion-sensing bandwidth, the timer is started. The
amount of shift is checked when the timer times out. If this check
finds that the amount of shift is within the
approach-completion-sensing bandwidth, approach completion is
assumed.
15553 Approach side feedrate upper limit
[Data type] Word
[Unit of data] mm/min
[Valid data range] 0 to 32767
[Standard setting value] 1200
Set an upper limit for the approach speed. A calculated approach
speed is clamped to this upper limit.
15554 Constant for approach side feedrate clamping
[Data type] Word
[Unit of data] mm/min
[Valid data range] 0 to 32767
Calculate the constant used for approach side feedrate clamping using
the formula below, then set the found value.
