(c) Continuous operation of interpolation control
When control method is linear or circular interpolation and operation method is Continuous, positioning
control
is different according to “Interpolation continuous operation type” of extended parameter. There are
「
Pass Target Position
」
in which the object goes through the specified target position and
「
Pass Near
Position
」
in which the object goes to the target position of the next step at the near position not exceeding
the specified target position.
The next describes
「
Interpolation continuous operation type
」
setting of extended parameter.

0 : Pass Target
Position
In case of Continuous operation from current step to next step,
the object passes the target position set on the operation data.
1 : Pass Near
Position
In case of Continuous operation from current step to next step,
the object goes to the target position of next step at the near
position not exceeding the target position set on the operation
data.
1) Continuous Operation Passing Target Position
「
Pass Target Position
」
Continuous Operation means that in case of Continuous operation from current
step to next step, the object passes the target position set on the operation data.
In general, when executing interpolation control passing the target position, there can be mechanical vibration
because of discontinuous operating speed caused by remaining moving amount at the last section where
operation data changes from current step to next step. The positioning module use the speed correction to
solve mechanical vibration problem and execute Continuous operation precisely at the target position set by
the user.
