Chapter 3 Before positioning
3- 20
(2) Speed override
While positioning by operation data, it is used to change operation speed by speed override
command (SOR instruction).
• Speed override command is available during acceleration, constant speed operation section and
executing speed override instruction in deceleration section during operation or dwell section may
cause Error 377 but the operation continues.
• Speed override setting ranges 1~100,000pps (setting unit: 1pps).
Remark
• Note that if a sudden difference between the current speed used for operation and a new
speed newly changed by speed override is excessive, it may cause a Step-over.
• During speed override, if target speed is smaller than bias speed. it will be operate by bias
speed.
(3) Speed override with position
Positioning speed override instruction changes its speed and keeps operating once it reaches the
set position during positioning operation by using speed override with position (PSO instruction).
• Positioning speed override instruction is available only in acceleration and regular speed
sections among operation patterns while the available operation modes are end operation,
continuous operation and sequential operation.
