On Axis 309
Locked
An axis is locked whenever either of the following two sets of conditions
are true:
Feedback on, electronic gearing off and no position-lock cam or
interpolated motion in progress:
No motion (Home, Move, Jog, or Time-Lock Cam) in progress.
No axis faults (drive fault, position error, encoder noise or loss,
hardware or software overtravel fault) exists.
The output voltage of the axis is not being limited to the servo
output limit parameter (Servo Output Limited).
Position error is less than or equal to position lock tolerance.
Feedback on, electronic gearing on or position-lock cam or
interpolated motion in progress:
No motion (Home, Move, Jog, or Time-Lock Cam) in progress.
No axis faults (drive fault, position error, encoder noise or loss,
hardware or software overtravel fault) exits.
The output voltage of the axis is not being limited to the servo
output limit parameter (Servo Output Limited).
Position error is less that or equal to position lock tolerance.
When you select Locked in: The:
Wait for Axis mode Current task pauses until the selected physical axis is
locked onto its command position (Lock_status = 1).
If Axis mode Program branches to the top (true) node if the selected
physical axis is locked onto its command position
(Lock_status = 1).
