11 SVR Virtual Motion Module
11.3.2 Motion Command Details
11-26
(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

OE)
• 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


• 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 logic program.
• The travel speed is calculated automatically.
• The Command Pause (OB

090) cannot be used.
• The Command Abort (OB

091) cannot be used.
• Change the 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
