CHAPTER 6 Increasing the robot operating speed
1 Increasing the robot operating speed
The robot operating speed can be increased by the following methods.
Use these methods as needed when programming.
(1) Increasing speed by arch motion
[Also refer to:] Robot controller user's manual
("Axis parameters" – "Arch position" in Chapter 4)
Programming manual
(ARCH statement in "10. Command statements".)
1- Gate motion
From point P1 to P4 via P2 and P3:
MOVE P, P2
MOVE P, P3
MOVE P, P 4
2- Arch motion: Using default arch position: (2000 pulses)
From point P1 to P2:
MOVE P, P2, Z=0
"Axis parameters" – "Arch position"
M1 (X-axis arch position) = 2000 pulses
M2 (Y-axis arch position) = 2000 pulses
M3 (Z-axis arch position) = 2000 pulses
M4 (R-axis arch position) = 2000 pulses
When the Z-axis moves upward from P1 and enters the M3 arch position range
(2000 pulses prior to Z=0), the X, Y and R axes begin to move. When these 3
axes enter the M1, M2 and M4 arch position range (2000 pulses prior to P2),
the Z-axis moves downward to P2. Compared with the gate motion 1, this arch
motion shortens the cycle time approximately 20% by moving the robot arm
along an arc.
