12.3.3 Near pass mode function
When carrying out continuous path control using interpolation control, either the
"positioning address pass mode" or the "near pass mode" can be selected by setting
the "
Pr.44 Near pass mode selection for path control".
The "near pass mode" can be selected as the "near pass mode function" to suppress
the mechanical vibration occurring during speed changes when carrying out
continuous path control using interpolation control. (Mechanical vibration may occur in
continuous path control due to the dropping of the output speed during speed
changes.)
(A) Positioning address pass mode (factory-set initial value)
The control is carried out so the machine passes the position set in "
Da.5
Positioning address/movement amount" of each positioning data unit being
continuously executed.
(B) Near pass mode
The extra movement amount occurring at the end of each positioning data unit
being continuously executed is carried over to the next positioning data unit.
By not carrying out alignment, the output speed drops are eliminated, and the
mechanical vibration occurring during speed changes can be suppressed.
Because alignment is not carried out, the operation is controlled on a path that
passes near the position set in "
Da.5
Positioning address/movement
amount".
The details shown below explain about the "near pass mode function".
