4.7 CPU/Master Stop and RESET State
Behavior at CPU-Master-STOP
Behavior at CPU-Master-STOP Response of the 1PosInc/Analog
• 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.
– Analog output QV+ is set to 0 V
– Digital output:
if the direction is assigned parameters for the DO
function, the digital output OUT=0 is set
• 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/Analog
• 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/Analog remains
current.
• The axis remains synchronized, and the actual value is
current.
• The following changed values remain valid:
– Voltage for rapid feed
– Voltage for creep feed
– Acceleration (T
acc
)
– Deceleration T
dec
– Switch-off and switchover difference
– The path difference for the monitoring of the direction of
rotation
remains 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.
