Description
If Safe Stop 1 (SS1) is configured:
0 = No Request
1 = Request Safe Stop 1
If Safe Stop 1 is not configured, this tag must be set
to 0. If set to 1, will cause SS1 fault.
Reserved for future use. This tag must be set to 0; will
cause SS2 fault if set to 1.
Reserved for future use. This tag must be set to 0; will
cause SOS fault if set to 1.
Reserved for future use. This tag must be set to 0; will
cause SMT fault if set to 1.
A 0 1 transition is required to reset Safety Faults. If
Restart Type is 'Manual' , a 0 1 transition is
required to restart a Safety Stop Functions.
Description
A collection of the following bits.
Safety Connection
0= Idle
1 = Run
Safety Connection
0=Normal
1= Faulted
Primary Feedback Position from drive-module safety
instance. Value is in encoder counts.
Primary Feedback Velocity from drive-module safety
instance. Value is in Rev/s or Meter/s.
Secondary Feedback Position from drive-module safety
instance. Value is in encoder counts.
Secondary channel may only be used for discrepancy
comparison with primary channel.
Secondary Feedback Velocity from drive-module safety
instance. Value is in Rev/s or Meter/s.
Secondary channel may only be used for discrepancy
comparison with primary channel.
A collection of the following bits.
