90485, SC arg Too low brake torque
Description
Too low brake torque in Safety Controller (SC) on mechanical
unit arg axis arg.
Probable causes
Axis has not been tested. Worn out brake(s).
Recommended actions
Check that the failing axis is activated. If failing axis is activated
replace brake(s) as soon as possible.
90486, SC arg CBC interrupted or incorrect
Description
Safety Controller (SC) has detected that the last Cyclic Brake
Check (CBC) on mechanical unit arg was interrupted or
incorrect.
Recommended actions
Check previous event messages. Perform a new brake check
only if needed, typically if event message 20485 also has been
displayed.
90487, SC arg Unsynchronized speed exceeded
Description
Exceeded axis speed when Safety Controller (SC) arg was
unsynchronized.
Recommended actions
Jog mechanical unit to synch position with low axis speed.
Reduce speed to 250 mm/s or 18 degrees/s.
90488, SC arg Unsynchronized time limit expired
Description
Available time to move the robot when unsynchronized has
expired for Safety Controller (SC) arg.
Recommended actions
Do a Confirm stop by pressing the Motors ON push button or
activate system input. Synchronize SC arg.
90489, SC arg has been disabled
Description
Safety Controller (SC) arg has been disabled and no supervision
functions are active.
Probable causes
Either a system reset has been performed or it's the first startup
of SC.
Operating manual - Troubleshooting IRC5
3HAC020738-001 Revision: AA
Recommended actions
Download a configuration to SC arg.
90490, SC arg OVR Speed exceeded
Description
Override (OVR) Speed limit exceeded on mechanical unit arg.
Probable causes
If Override (OVR) is active, then OVR speed limitations will be
active.
Recommended actions
Decrease speed. Deactivate OVR.
90491, SC arg Override active during startup
Description
Override digital input was active during startup on SC arg.
90492, SC arg SST violation in Brake test
Description
Movement detected during Brake test on Safety Controller (SC)
arg. Mechanical unit arg. Axis arg.
Probable causes
Interrupted braketest. Worn out Brakes.
Recommended actions
Restart CBC. Replace Brake.
90493, SC arg SBR triggered
Description
Safe Brake Ramp (SBR) on Safety Controller (SC) was
interrupted by a Class 0 stop due to slow deceleration on
mechanical unit arg. This is normal and occurs in cases when
a stop1 is to slow. Check for other safety controller event
messages.
Recommended actions
Change parameter value for SBR in Motion configuration.
Trigger a new stop to test the Brake Ramp. If this happens
frequently, check the Application manual for mechanical units'
configuration.
90494, SC arg Tool change incorrect
Description
Incorrect tool change with Tool arg on mechanical unit arg.
