11 SVR Virtual Motion Module
11.3.2 Motion Command Details
11-30
(7) STEP Operation (STEP)
The STEP command executes positioning for the specified travel direction, moving amount, and travel speed.
Parameters related to acceleration and deceleration are set in advance. The speed can be changed during axis
movement.
(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.
