Table 7-3 Causes Of Errors For Pos_Err - Siemens simatic et 200s Operating Instructions Manual

Causes of Errors for POS_ERR
Table 7-3 Causes of Errors for POS_ERR
Error Number Cause
1 MODE unknown
2 ERR_2L+ is displayed
3 ERR_ENCODER is displayed
4 The axis is not synchronized (SYNC=0)
5 The limit switch that lies in the direction in which
the drive is moved is active
7 Inching: DIR_P and DIR_M = 1
Absolute positioning:
Start with DIR_P and DIR_M = 0 or relevant
control bit DIR_P or DIR_M = 0
Relative positioning:
Start with DIR_P and DIR_M = 0 or DIR_P and
DIR_M = 1
8 Absolute positioning :
Destination ≥ end of rotary axis at incremental
encoders or destination ≥ encoder range at SSI
encoders
9 Absolute positioning was terminated because
JOB 9 was initiated
10 Search for reference: Reference point coordinates
≥ end of rotary axis
11 Search for reference:
No reference signal found up to the limit switch or
between the limit switches
13 Direction of rotation of the drive and the encoder
varies
15 Inching, relative positioning:
In dosing operation DIR_M = 1

Remedy
Permissible MODEs are:
MODE 0
•
MODE 1
•
MODE 3 (not possible at SSI encoders or in
•
dosing operation)
MODE 4
•
MODE 5 (not possible in dosing operation)
•
Check the load voltage (2L+) at terminal 7
Check the encoder wiring
SSI encoder:
Eliminate the encoder error.
•
The axis can be synchronized at incremental
encoders and non-activated dosing operation

Search for Reference
•
Reference Signal Evaluation
•
Setting of Actual Value
•
Check your switches and the wiring as well as the
DI0 limit switch minus and DI1 limit switch plus
parameters
Check your switches, the encoder and the wiring
Check the wiring of the drive and the encoder as
well as the reversal of the direction of rotation
