b) Detailed description of the status bits
Bit 0
:
target position reached
This bit is set:
- when a transferred target position has been reached successfully (not at the
end of a manual run, elsewise the target position is the same as the
applicable limit switch)
- after manual displacement while at standstill, when the actual position is
within the positioning window again
This bit is reset:
- after transferring a target position if the difference from the actual value is
larger than the positioning window (Par. 44)
- by a manual run
- if an invalid target value has been transferred
- if rotated manually when on standstill
Bit 1
:
drag error
This bit is set:
- if during a run (except in the braking phase) the difference between actual
target position and actual position exceeds the value which has been set with
Par. 46
This bit is reset:
- with each new run command
Bit 2
:
reserved
