outside reference position
1 Power–up inhibit
The system can only be powered–up using ”OFF 1”
followed by ”ON”.
0 No power–on inhibit
1 Warning present
The drive still remains operational. Acknowledgment is
not required.
Which warning is present?
––> refer to P953 (warnings)
and
––> P954 (supplementary information, faults/warnings)
0 Warning not present
1 No following error
The dynamic target (reference) actual position comparison
is made within the defined following error window.
The following error window is defined using P12
(maximum following error) (refer to Chapter 5.6.2).
0 Following error
1 Master, Class 1
0 No master Class 1 (but master, Class 2)
Note:
Before SW 1.4 the following applies:
The signal is not supported (a permanent ”1” signal).
1 Reference position reached
Before SW 1.6 the following applies:
The position reference value is located at the end of
a traversing task within the positioning window.
The traversing task is interrupted by a fault, stop or
OFF commands.
The following is valid SW 1.6:
The behavior is dependent on P56, bit 3:
P56.3=1
– The position reference value is located at the end
of a traversing task within the positioning window.
P56.3=0
– The position reference value is located at the end
of a traversing task within the positioning window.
– The traversing task was interrupted by a fault,
stop or OFF commands.
0 Outside the reference position
