8.3 Motion Commands
8-27
( 5 ) Latch (LATCH)
The latch function cannot be used for the SVR. The LATCH command will thus perform the same
operation as the INTERPOLATE command.
[ a ] Operating Procedure
（ Note） The following position information is updated during command execution.
• Machine Coordinate Target Position (TPOS) (IL††0E)
• Target Position (CPOS) (IL††10)
• Machine Coordinate System Position (MPOS) (IL††12): MPOS is always equal to CPOS.
• Machine Coordinate Feedback Position (APOS) (IL††16): APOS is always equal to CPOS.
No. Execution Conditions Confirmation Method
1 There are no alarms. Both IL††02 and IL††04 are 0.
2 The Servo ON condition. IB††001 is ON.
3 Motion command execution has been completed. IW††08 is 0 and IB††090 is OFF.
Set the motion setting parameters.
• Target Position: OL††1C
• Acceleration/Deceleration Filter Type:
OW††03
• Speed feed forward compensation can be applied.
• Generate the target position data each high-speed scan from the ladder
program.
• The travel speed is calculated automatically.
• The Command Pause (OB††090) cannot be used.
• The Command Abort (OB††091) cannot be used.
• Change a motion command to stop interpolation execution.
Execute the LATCH motion command.
• Set OW††08 to 6.
Positioning starts.
• IW††08 will be 6 during execution.
Change the Target Position (OL††1C) every
high-speed scan.
Positioning Completed
• IB††0C1 will turn ON.
Execute NOP motion command.
• Set OW††08 to 0.
