Safeguard
A barrier guard, device or safety procedure designed for the protection of
personnel. (R15.06)
Safety Integrity Level
Safety Integrity Level (SIL) is IEC’s method for determining the
performance level of a safety system. SIL 2 corresponds to ISO
Performance Level “d”, and SIL 3 corresponds to ISO Performance Level
“e”. ISO 10218 allows for the use of either.
Safety Logic Circuit
The safety logic circuit monitors safety critical external devices such as
the light curtains and FSU generated signals. The safety logic circuit is
programmed via an intuitive user interface that is supported on the
YASKAWA Programming Pendant. It enables to set up the logical
operations, such as stopping the Robot or outputting a signal if the servos
are on.
Safety Monitored Stop
Collaborative feature designed to allow safe human-robot interaction.
Only when robot motion ceases can the human safety enter the
collaborative workspace. Servos can remain energized in accordance with
a category 2 stop in accordance with ISO 10218-1:2011, 5.4. A risk
assessment shall be used to determine if any additional safeguarding is
necessary to mitigate risks within the robot system.
SCARA Robot
A cylindrical robot, having two parallel rotary joints (horizontally
articulated) and provides compliance in one selected plane. (ISO 8373)
Second Home Position
Apart from the “home position” of the Robot, the second home position
can be set up as a check point for absolute data. The initial value of the
second home position is the home position (where all axes are at pulse 0).
The second home position can be changed.
Security Mode
Levels of operator modes on the Controllers, include: Operation mode,
Edit mode, Management mode, Safety mode and One Time Management
mode.
Sensor
Instruments used as input devices for robots, which enable it to determine
aspects regarding the robot's environment, as well as the robot's own
positioning. Sensors respond to physical stimuli (such as heat, light,
sound, pressure, magnetism and motion), and they transmit the resulting
signal or data for providing a measurement, operating a control or both.
