Operations of each contact
• The BUSY flag for the axis 1 and 2 (FPΣ: X118, X119, FP2: X18, X19) indicating the state that a motor
is running turns on when the position control started, and it turns off when the operation completed.
• The operation done flag for the axis 1 and 2 (FPΣ: X120, X121, FP2: X20, X21) indicating the state that
an operation completed turns on when the position control completed, and it will be held until any
operation among the position control, JOG operation, home return and pulser operation starts. The
timing of that the flag turns on is at the time that the current value of the AMP became within the
completion width specified in the parameter setting of the Configurator PM after sending the command
to move to the target position.

Precautions on programming
• To start the interpolation control, turn on the positioning start contact of the axis with the smallest
number in the same group.
• In case of the center point specification, the X-axis auxiliary point is the center point of X axis, and the
Y-axis auxiliary point is the center point of Y axis. In case of the pass point, each pass point is set as
the pass point of X axis and Y axis.
• When the control method is increment, both the center point and pass point are the increment
coordinate from the start point.
• When the start point and the operation done point is the same, it performs one circular operation when
using the center point method. However, when using the pass point method, an error occurs.
• In case of the pass point method, when the start point, pass point and operation done point exist in the
same straight line, an arc is not comprised, and an error occurs.
• When setting the long axis speed, the composite speed is faster than the long axis speed.
• If any value such as a movement amount, acceleration time, deceleration time or target speed is out of
the specified range, a setting value error will occur when the position control starts.
• The number of the startup contact and flag varies depending on the number of axes and the installation
position.
• The specified slot number varies depending on the installation position of the unit.
