Axis Operating Input Memory Areas
Section 4-8
Example: Executing RELATIVE MOVEMENT COMMAND.
The PCU Positioning Completed Flag will not turn ON when axis operation
stops under the following conditions.
• Stops due to an error during positioning.
• Stops due to DECELERATION STOP or EMERGENCY STOP sent during
positioning.
• Jogging (JOG) stops.
The PCU Positioning Completed Flag will also not turn ON when axis opera-
tion stops during positioning due to DECELERATION STOP or EMERGENCY
STOP, even if the position is within the
Positioning Completion Range 1
speci-
fied for the original target position.
The PCU Positioning Completed Flag will turn OFF when the power is turned
ON, a connection is released, another axis operation is started successfully
(including jogging, speed control, and torque control), or Servo Unlock is exe-
cuted.
Note
On machines for which position deviation occurs between the feedback posi-
tion and target position (command position) when the axis is stopped, such as
pushing a load or using a vertical axis, the PCU Positioning Completed Flag
will not turn ON if the set value for the
Positioning Completion Range 1
is too
small. Adjust the set value for the
Positioning Completion Range 1
to suit the
operating conditions for the machine.

Time
The Receiving Command Flag remains
ON for at least one cycle time after the
positioning command is received.
The PCU Positioning Completed Flag is turned OFF
when a movement command is executed.
The PCU Positioning Completed Flag is turned ON when
the number of the Servo Drive's deviation counter
residual pulses is less than the value set for the
positioning completion range. Depending on the number
of deviation counter residual pulses when pulse output
has been completed, a delay may occur in the time
between when the pulse output from the Position Control
Unit is completed until positioning has been completed.
