DISPLAY/SETTING DATA
Item Description
Target speed
Indicates the target speed for positioning data, OPR or JOG operation.
For interpolation control, the composite speed or reference axis speed is displayed for the
reference axis and 0 appears for the interpolation axis.
Buffer memory address (Axis #1): 820, 821
Feed speed
Shows the speed of the axis operating actually in any operation.
For interpolation control, the composite speed or reference axis speed is displayed for the
reference axis and 0 appears for the interpolation axis.
Buffer memory address (Axis #1): 804, 805
Current speed
Indicates the current speed.
For interpolation control, the composite speed or reference axis speed is displayed for the
reference axis and 0 appears for the interpolation axis.
0 appears for JOG operation or MPG operation.
Buffer memory address (Axis #1): 810, 811
V/P switch changed travel
correction register
Indicates the travel distance under position control when velocity control is changed to
position control during velocity/position switching control.
Buffer memory address (Axis #1): 814, 815
Travel register
Indicates the value set to the velocity/position switching control travel correction register in
the sequence program.
Buffer memory address (Axis #1): 1526, 1527
Velocity/position switching
latch flag
Indicates the velocity/position switching latch flag for the status signal.
(ON) indicates that
velocity control is switched to position control.
Buffer memory address (Axis #1): 817
Velocity/position switching
enable flag
Indicates the velocity/position switching enable flag set in the sequence program.
(ON) indicates that switching by the velocity/position switching signal is valid.
Buffer memory address (Axis #1): 1528
Velocity control in progress
flag
Indicates the signal for differentiating between velocity control and position control.
(ON) during velocity control.
Buffer memory address (Axis #1): 817(b0)
