Operating Instructions, 05/2007, A5E00124871-04
Cause
ERR_ENCODER is displayed
The axis is not synchronized (SYNC=0)
The limit switch that lies in the direction in which
the drive is moved is active
Absolute positioning:
Start with DIR_P and DIR_M = 0 or relevant
control bit DIR_P or DIR_M = 0
Absolute positioning:
destination ≥ end of rotary axis
Absolute positioning was terminated because
JOB 9 was initiated
Direction of rotation of the drive and the
encoder varies
6.6 Functions of the 1PosSSI/Analog
What to Do
Check the encoder wiring
You can synchronize the axis with:
Reference point run
•
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 the wiring of the drive and the encoder
as well as the reversal of the direction of
rotation parameter
