Pertinent Diagnostic Messages
• A0011 Starting lockout active
• E3110 Time interval for forced dynamization exceeded
• F8027 Starting lockout while drive enabled
The following configurable control sections can use the integrated safety
functions if they have been equipped with the optional safety module S1:
• single-axis ADVANCED
• double-axis BASIC UNIVERSAL
Features
• Safety related stopping process:
• "Safety related standstill" corresponding to stop category 1
according to EN 60204-1 (with drive-controlled best possible
deceleration and time monitoring)
or, alternatively,
• "Safety related operational stop" corresponding to stop category 2
according to EN 60204-1, i.e. the drive control remains active.
Transition to standstill is carried out by the NC. Using 2 channels,
the drive monitors the attainment of standstill within the preset
tolerance time
additionally
• "Safety related drive interlock" → like "Safety related standstill", but
switching to "Safety related motion" by actuating the enabling
control device is not possible
Safety switches S1/S2
standstill"/"Safety related operational
ASP1/ASP2 are used to select the starting lockout.
• Safety related motion:
• Safety related reduced speed
→ 2-channel monitoring for exceeding a velocity threshold
• Safety related direction of motion
→ 2-channel monitoring for allowed direction of motion
• Safety related limited increment
→ 2-channel monitoring for allowed travel distance
• Safety related limited absolute position
→ 2-channel monitoring for allowed absolute position. Safety
related homing must be executed for the safety related absolute
position!
• Safety related acceleration/deceleration
→ 2-channel monitoring for maximum deceleration/acceleration
• Safety related feedback:
• Safety related diagnosis outputs
→ to transfer the "Safety related status" to additional system
components
• Safety related safety door
→ A drive that functions as the diagnostic master can summarize
the safety related status of several axes within a protective zone
and control a safety door.
