3.7 CPU/Master Stop and RESET State
Behavior at CPU-Master-STOP
Behavior at CPU-Master-STOP Response of the 1PosInc/Digital
• Due to power-off of the CPU/DP master
or
• Due to power-off of the IM 151/ IM 151 FO
or
• Due to failure of DP transmission
or
• Due to change from RUN to STOP
• The current run is stopped.
• All 3 digital outputs are set to 0.
• Feedback bit POS_ERR = 0
• Feedback bit POS_DONE = 1
Exiting the CPU-Master-STOP Status
Exiting the CPU-Master-STOP Status Response of the 1PosInc/Digital
• At power-on of the CPU/DP master
or
• At power-on of the IM 151/ IM 151 FO
or
• After failure of the DP transmission
or
• After a change from STOP to RUN
• The feedback interface of the 1PosInc/Digital remains
current.
• The axis remains synchronized, and the actual value is
current.
• 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.
RESET state of the 1PosInc/Digital
RESET Status of the 1PosInc/Digital and Modification of
the Parameters of the 1PosInc/Digital
Response of the 1PosInc/Digital
• By changing the parameters of the 1PosInc/Digital
and downloading the parameter assignment and
configuration of the ET 200S station to the CPU/ DP
master
or
• As a result of power-on of the power module of the
1PosInc/Digital
or
• Inserting the 1PosInc/Digital in an energized state
• The axis is not synchronized and the actual value = 0.
• 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.
