*3 Only valid during continuous trajectory control, VPF/VPR, VVF/VVR. When setting torque limit in another control mode, set the torque
limit value at start in positioning data item. When not using torque limit value during operation, set "0". When both torque limit during
operation and torque limit at start are set in VVF/VVR, torque limit at start is valid.
*4 When the "speed control 10 multiplier speed setting for degree axis" is set to "valid", the setting range is 1 to 214748364710

Processing details
■Controls
• Request a direct positioning start to the Motion CPU from the data stored in the positioning data area of the device of the
self CPU specified with (S2) and after.
• It is necessary to take an inter-lock by the start accept flag of CPU buffer memory and user device so that multiple
instructions may not be executed toward the same axis of the same Motion CPU No.
Refer to the start accept flag (system area) for details of the start accept flag. (Page 82 Start accept flag
(System area))
■Operation
Outline operation between CPUs at the MP.SVSTD and DP.SVSTD instruction execution is shown below.
• MP.SVSTD instruction
*1 Set in [Motion CPU Common parameter]  [Basic Setting]
• DP.SVSTD instruction
*1 Set in [System Parameter]  [Multiple CPU settings] in GX Works3
*2 Set in [Motion CPU Common parameter]  [Basic Setting]
