14.33 PLC Axis Control
Control signals (PLC axis control information data)
Control signals such as start, interlock, reset, axis removal and axis removal 2 are designated for the PLC axis.

bit0: Start
Starting begins at the rising edge (OFF -> ON) of the start signal, based on the control information data.
The axis does not move during interlock, servo OFF, axis detachment and axis detachment 2.
Movement starts after interlock, servo OFF, axis detachment and axis detachment 2 are canceled.
Start is invalid during resetting.
bit1: Interlock
The moving PLC axis executes a deceleration stop when the interlock signal turns ON.
The stopped PLC axis will resume movement when the interlock signal turns OFF (is canceled).
bit2: Reset
The PLC axis is reset when the reset signal turns ON.
Moving PLC axes will execute a deceleration stop.
Commands and controls are invalid during resetting.
If the reset signal turns ON during an alarm occurrence, the alarm will be cleared.
bit3: Servo OFF
The PLC axis will execute a deceleration stop and its servo will turn OFF when the servo OFF signal turns ON.
Whether the PLC axis movement is compensated during servo OFF can be selected in the basic specification parameter
"#1064 svof".
A servo ON status will result when the power is turned ON.
bit4: Axis removal
The axis will execute a deceleration stop, and a servo OFF status will result, when the "axis detachment" signal turns ON.
A servo ON status will result and the stopped PLC axis will resume movement when the "axis detachment" signal turns
OFF (is canceled).
Axis removal is validated when either this signal or machining parameter and axis parameter "#8201 Axis Removal" is
validated.
The reference position return will become incomplete when the axis is detached. Therefore, a dog-type reference position
return must be completed again when starting with an absolute command.
bit5: Axis removal 2
The axis will execute a deceleration stop, and a servo OFF/ready OFF status will result, when the "axis detachment 2"
signal turns ON.
A servo ON/ready ON status will result for the stopped PLC axis when "axis detachment 2" signal turns OFF (is canceled).
A restart must be executed to start the movement again.
Position control cannot be carried out while the "axis detachment 2" signal is ON. However, position detection is possible
so the position will not be lost.
bit8: Absolute value command
Turn this bit ON when the movement data is issued with absolute command.
When this bit is OFF, the commands will be processed as incremental commands.
