This function inputs/outputs safety-related signals through a redundant terminal. If a signal that is different from the redundant safety input or output signal is detected, the system determines whether it is a short circuit or hardware defect and stops the robot with STO Stop Mode. To set the Safety I/O, go to the Robot Workcell and select Robot > Safety I/O.
Signal Name | Description |
|---|
Emergency Stop (L) | It is an interface to receive emergency stop signal from peripheral device, or connect additional emergency stop switches. - High: Normal operation
- Low: It stops the robot according to the stop mode setting for Emergency Stop at the Safety Stop Mode.
|
Emergency Stop – No Loopback (L) | It is an interface to receive emergency stop signal from peripheral device, or connect additional emergency stop switches. This signal doesn’t activate ‘Emergency Stop – excl. No Loopback Input’ safety outp - High: Normal operation
- Low: It stops the robot according to the stop mode setting for Emergency Stop at the Safety Stop Mode.
|
Protective Stop (L) | It can be linked with Safeguarding Devices such as safety matts, light curtains and laser scanners. - High: Normal operation
- Low: It stops the robot according to the stop mode setting for Protective Stop at the Safety Stop Mode.
|
Protective Stop – STO (L) | - High: Normal operation
- Low: Immediately cuts the motor power and engages the brakes to force the robot to stop.
|
Protective Stop – SS1 (L) | - High: Normal operation
- Low: Cuts off the motor power and engages the brakes after controlled stop.
|
Protective Stop – SS2 (L) | - High: Normal operation
- Low: Position is maintained with power supplied to the motor and the brake disengaged after controlled stop.
|
Protective Stop(L) - Auto Reset & Resume (R) | Unlike the other Protective Stop, Interrupted state can be reset and automatic operation can be resumed automatically by this signal. This enables automatic restart after Safety-rated Monitored Stop described in ISO TS 15066. - Low: Follow Protective Stop – SS2.
- Rising (Low to High): the task resumes automatically without manual reset or resume.
Warning
Resuming automatic operation without manual intervention can be dangerous,
DO conduct a comprehensive risk assessment to confirm that using this signal is safe
|
Interlock Reset (R) | It is used to reset the Interrupted state by Protective Stop - Rising(Low to High): Reset the restart interlock and permit return to normal standby state
|
Reduced Speed Activation (L) | - High: Operates the robot at the normal speed set in the task
- Low: It operates the robot at a speed proportionately reduced from the speed set in the task. The reduction ratio can be adjusted using the Speed Reduction Ratio slide bar. If a signal is detected within a Collaborative Zone, the robot is operated at the smaller speed reduction ratio (slower) between the main speed reduction ratio and the Collaborative Zone speed reduction ratio.
|
3 Pos Enable Switch (H) | This is operation permission equipment that is used to connect a three-position enabling switch. - High: Jog/Servo On are available in Manual Mode
Play/Resume/Servo On are available in Auto Mode - Low: Jog/Servo On are prohibited in Manual Mode
Play/Resume/Servo On are prohibited in Auto Mode
|
Handguiding Enable Switch (H) | It is an operation permission signal used to connect a hand guide switch. - High: Hand-guiding available
- Low: Hand-guiding unavailable
|
HGC End & Resume (R) | It is used to resume task program execution after operator’s HandGuiding Control(HGC) in Auto Mode - Rising(Low to High): Resumes task program after the handguiding control.
|
Safety Zone Dynamic Enable (H) | It is available that activating/deactivating Space Limit and/or Zone dynamically. - High: Activates the Space Limit or Zone set to be temporarily enabled or disabled by this signal
- Low: Deactivates the Space Limit or Zone set to be temporarily enabled or disabled by this signal
|
Safety Zone Dynamic Enable (L) | It is available that activating/deactivating Space Limit and/or Zone dynamically. - High: Deactivates the Space Limit or Zone set to be temporarily enabled or disabled by this signal
- Low: Activates the Space Limit or Zone set to be temporarily enabled or disabled by this signal
|
Remote Control Enable (L) | Used to enable the Remote Control Mode. - High: Remote Control Mode enabled.
- Low: Remote Control Mode disabled.
|
Signal Name | Description |
|---|
Emergency Stop (L) | It is used to notify that emergency stop is required to peripheral devices, such situation as - Emergency Stop Button is pushed on robot accessories (Teach pendant, Smart Pendant, Emergency Button Box) - Emergency Stop from the dedicated Safety Input - Emergency Stop (L) from the configurable Safety Input - Emergency Stop – No Loopback(L) from the configurable Safety Input. - High: Normal operation
- Low: Emergency stop required
|
Emergency Stop – excl. No Loopback Input (L) | It is used to notify that emergency stop is required to peripheral devices, such situation as - Emergency Stop Button is pushed on robot accessories (Teach pendant, Smart Pendant, Emergency Button Box) - Emergency Stop from the dedicated Safety Input - Emergency Stop (L) from the configurable Safety Input The case of Emergency Stop – No Loopback(L) from the configurable Safety Input is EXCLUDED. Deadlocks can be avoided by not sending back the emergency stop signal to the peripheral device that originally sending emergency stop signal to robot. - High: Normal operation
- Low: Emergency stop required
|
Safe Torque Off (L) | - High: Robot is not in Servo Off, Emergency Stop state
- Low: Robot is in Servo Off or Emergency Stop state
|
Safe Operating Stop (L) | - High: Robot is not in Standby state
- Low: Robot is in Standby state, and standstill monitoring is activated.
|
Abnormal (L) | - High: Robot is not in Interrupted, Recovery, Auto Measure state
- Low: Robot is in Interrupted, Recovery, or Auto Measure state
|
Normal Speed (L) | - High: Robot is operating at the reduced speed due to external Reduced Speed Activation safety input
- Low: Robot is operating as normal speed
|
Reduced Speed (L) | - High: Robot is operating as normal speed
- Low: Robot is operating at the reduced speed due to external Reduced Speed Activation safety input
|
Auto Mode (L) | - High: The robot is not in Auto Mode
- Low: The robot is in Auto Mode
|
Manual Mode (L) | - High: The robot is not in Manual Mode
- Low: The robot is in Manual Mode
|
Remote Control Mode (L) | - High: The robot is not in Remote Control Mode
- Low: The robot is in Remote Control Mode
|
Standalone Zone (L) | - High: The robot’s TCP is in a Collaborative Zone
- Low: The robot’s TCP is not in any Collaborative Zone
|
Collaborative Zone (L) | - High: The robot’s TCP is not in any Collaborative Zone
- Low: The robot’s TCP is in a Collaborative Zone
|
High Priority Zone (L) | - High: The robot’s TCP is not in any Collision Sensitivity Reduction Zone and not in a High Priority Zone option checked Custom Zone
- Low: The robot’s TCP is in a Collision Sensitivity Reduction Zone or in a High Priority Zone option checked Custom Zone
|
Tool Orientation Limit Zone (L) | - High: The robot’s TCP is not in any Tool Orientation Limit Zone
- Low: The robot’s TCP is in a Tool Orientation Limit Zone
|
Designated Zone (L) | This is used to confirm if the TCP (Tool Center Point) is inside the user-defined Zone. The Designated Zone signal defined on the Safety Output setting UI can be selected from the Zone setting UI - High: If the TCP is not inside any Zone linked with the Designated Zone safety output
- Low: If the TCP is inside a Zone linked with the Designated Zone safety output
