Safety Fn State STO 1A10h
Bool
-
STO active
Set if the STO safety function is active and torque/force is removed from
the drive. The activation may be a result from a demand of the Safety
Application Process of a fault reaction from a fault in the safety fault buffer
or a demand from the PROFIdrive on PROFIsafe Safety Function State
Machines.
Cleared if the STO safety function is inactive and torque/force may be
generated from the drive.
This bit can also be accessed via UPID 1A06h bit 0.
STO Selected
1A1Ah
Bool
-
STO selected
The safety module has detected a request for STO, this can also be an
internal event.
This bit can also be accessed via UPID 1A06h bit 10.
Safety Fn State Error 1A1Dh
Bool
-
Error active
This flag is set if an error on the safety module is active.
Cleared if no error is active.
This bit can also be accessed via UPID 1A06h bit 13.
Safety Fn State Int
Event
1A1Eh
Bool
-
Acknowledge is
required
Set if an explicit acknowledge is required as an interface event.
Cleared if no acknowledge is required.
This bit can also be accessed via UPID 1A06h bit 14
Safety Fn State
Brake Released
1A20h
Bool
-
Brake is
released
Set if the brake is actively driven and should be released (not braking).
Cleared if the brake is not driven and should be braking.
This bit can also be accessed via UPID 1A06h bit 16.
Safety Fn State
Brake Tst time Ov
1A21h
Bool
-
Brake Test Time
elapsed
Set if the time, specified in parameter 47DAh “SBT Request Interval” is
elapsed. A brake test must be performed to clear this flag. Then the
interval time restarts counting.
Cleared if the brake test interval, specified in parameter 47DAh has not
elapsed.
This bit can also be accessed via UPID 1A06h bit 17.
Safety Fn State SBT
runs
1A22h
Bool
-
SBT runs
SBT sequence is running.
This bit can also be accessed via UPID 1A06h bit 18.
Safety Fn State
Brake Tst Failed
1A23h
Bool
-
Brake Test
failed
An error during the brake test has been detected.
Possible causes: brake does not work correctly, motor has moved.
Recommended actions: Check brake, check wiring.
This bit can also be accessed via UPID 1A06h bit 19.
