8.1 Basic Operation
8-11
Operation of input control/output control signals
• When a positioning start request (corresponding bit allocated to UM00192 to UM00197)
turns on by a user program, the positioning control will start. The positioning start request will
be enabled at the edge where it turns on.
• A busy flag (corresponding bit allocated to UM00090 to UM00095), which indicates that a
requested operation is being controlled, will turn on when the positioning control starts, and it
will turn off when the operation completes.
• An operation done flag (corresponding bit allocated to UM00096 to UM0009B), which
indicates the completion of operation, will turn on when the current operation is completed,
and it will be held until the next positioning control, JOG operation, or home return starts.
• When a J-point speed change request (corresponding bit allocated to UM001BC to
UM001C1) turns on, the target speed will change. The speed change request will be
enabled at the edge where it turns on.
• When a J-point positioning start request (corresponding bit allocated to UM001C2 to
UM001C7) turns on, the next positioning control will start.

the value of each bit is 1, it turns on. When the value of each bit is 0, it turns off.

Behaviors when the speed change request turns on while the positioning unit is
accelerating or decelerating the speed
A speed change is possible during J-point control, but impossible during acceleration or
deceleration. A speed change will be made after the unit goes to constant speed when the
speed change signal turns on during acceleration or deceleration. Be sure to input the amount
of movement for positioning with a value that can secure a target constant-speed area.
J-point speed change contact is not effective.
