Description
Storage details
This area stores the states (ON/OFF) of various flags.
Information on the following flags is stored.
■
In speed control flag
This signal that comes ON under the speed control can be used to judge whether the operation is performed under the speed
control or position control. The signal goes OFF when the power is switched ON, under the position control, and during JOG
operation or manual pulse generator operation. During the speed-position or position-speed switching control, this signal comes
ON only when the speed control is in effect. During the speed-position switching control, this signal goes OFF when the speed-
position switching signal executes a switching over from speed control to position control. During the position-speed switching
control, this signal comes ON when the position-speed switching signal executes a switching over from position control to speed
control.
■
Speed-position switching latch flag
This signal is used during the speed-position switching control for interlocking the movement amount change function. During the
speed-position switching control, this signal comes ON when position control takes over. This signal goes OFF when the next
positioning data is processed, and during JOG operation or manual pulse generator operation.
■
Command in-position flag
This signal is ON when the remaining distance is equal to or less than the command in-position range (set by a detailed
parameter). This signal remains OFF with data that specify the continuous path control (P11) as the operation pattern. The state of
this signal is monitored every 0.9ms except when the monitoring is canceled under the speed control or while the speed control is
in effect during the speed-position or position-speed switching control. While operations are performed with interpolation, this
signal comes ON only in respect of the starting axis. (This signal goes OFF in respect of all axes upon starting.)
■
OPR request flag
This signal comes ON when the power is switched ON, when the drive unit READY signal goes OFF, when the PLC READY signal
goes ON, when a machine OPR operation starts. This signal goes OFF when a machine OPR operation completes.
■
OPR complete flag
This signal comes ON when a machine OPR operation completes normally. This signal goes OFF when the operation starts, when
the drive unit READY signal goes OFF or PLC READY signal goes ON.
■
Position-speed switching latch flag
This signal is used during the position-speed switching control for interlocking the command speed change function. During the
position-speed switching control, this signal comes ON when speed control takes over. This signal goes OFF when the next
positioning data is processed, and during JOG operation or manual pulse generator operation.
■
Axis warning detection flag
This signal comes On when an axis warning is reported and goes OFF when the axis error reset signal comes ON.
■
Speed change 0 flag
This signal comes ON when a speed change request that specifies 0 as the new speed value is issued. This signal comes ON
when a speed change request that specifies a new speed value other than 0 is issued.
