Absolute positioning: Causes of Errors for POS_ERR
You must find out the causes of errors with JOB 15 (displays current values).
Error Number Cause What to Do
1 Impermissible MODE in dosing operation
2 ERR_2L+ is displayed Check the load voltage (2L+) at
terminal 7
3 ERR_ENCODER is displayed Check the encoder wiring
4 The axis is not synchronized (SYNC=0) You can synchronize the axis with:
• Reference point run
• Reference Signal Evaluation
• Setting of Actual Value
5 The limit switch that lies in the direction in
which the drive is moved is active
Check your switches and the wiring
as well as the DI0 limit switch minus
and DI1 limit switch plus parameters
7 Start with DIR_P and DIR_M = 0 or relevant
control bit DIR_P or DIR_M = 0
8 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 (only at incremental
encoders)
13 Direction of rotation of the drive and the
encoder varies
Check the wiring of the drive and
the encoder as well as the reversal
of the direction of rotation parameter
