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
2 ERR_2L+ is displayed Check the load voltage (2L+) at
terminal 15
3 ERR_ENCODER is displayed Check the encoder wiring
4 The axis is not synchronized (SYNC=0) Eliminate the encoder error.
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 Absolute positioning:
Start with DIR_P and DIR_M = 0 or relevant
control bit DIR_P or DIR_M = 0
8 Absolute positioning: Destination ≥ encoder
range
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
