7.7 CPU /Master Stop and RESET State
Response of the 1PosU
The current run is stopped.
•
All 3 digital outputs are set to 0.
•
Feedback bit POS_ERR = 0
•
Feedback bit POS_DONE = 1
•
Response of the 1PosU
The feedback interface of the 1PosU remains current.
•
The axis remains synchronized, and the actual value is
•
current.
The moved encoder range remains valid.
•
The changed switch-off and switchover differences and the
•
path difference for the monitoring of the direction of rotation
remain valid.
An initiated JOB 9: Evaluating the Reference Signal and JOB
•
10: Latch function remains active.
The feedback bit selected with JOB 15 is current.
•
Response of the 1PosU
The axis is synchronized, and the actual value corresponds
•
to the current encoder value.
The encoder range has not been moved.
•
The switch-off and switchover difference is accepted from
•
the parameters.
The path difference for the monitoring of the direction of
•
rotation is set at double the switch-off difference.
JOB 9: Evaluating the Reference Signal and JOB 10: Latch
•
function are not active.
The residual distance is displayed as a feedback value.
