Behavior at CPU-Master-STOP

Introduction
The 1STEP 5V/204kHz detects the CPU-master STOP. It responds by canceling the current
positioning operation.
Exiting the CPU-Master-STOP Status
ET 200 S Station
Without reassigning the parameters of the
ET 200 station
With reassignment of the parameters of the
ET 200 station
Parameter Reassignment at the ET 200S Station
A new parameter assignment of the ET 200S station by means of your CPU/ DP master
takes place:
● Upon power on of the CPU/DP master
● Upon power on of the IM 151/IM 151 FO
● After failure of the DP transmission
● After loading an altered parameter assignment or configuration of the ET 200S station
● When the 1STEP 5V/204kHz is inserted
● Upon power on or inserting of the appropriate power module

remains current.
The values changed by means of parameter
•
assignment job are maintained.
If a control bit was set (DIR_P, DIR_M, C_PAR)
•
when the CPU-Master-STOP occurred, the bits
STS_JOB and ERR_JOB are set when the
CPU-Master- STOP status is exited. Delete the
control bit. The run/parameter job is not
executed. You can then start a new search by
means of the control bit.
After the delay ramp, the pulse enable, the
•
RDY LED, and the SYNC status bit are deleted.
Information on previous searches and parameter
•
assignment jobs is reset.
If pulse enable was activated by means of the
•
control bit DRV_EN at the time of the
CPU-Master-STOP, the pulse enable, the RDY
LED, and the SYNC status bit are deleted after
the delay ramp.
