Cause
Impermissible MODE in dosing operation
ERR_2L+ is displayed
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
Start with DIR_P and DIR_M = 0 or relevant
control bit DIR_P or DIR_M = 0
Destination ≥ end of rotary axis (at
incremental encoders) or destination ≥
encoder range (at SSI encoders)
Absolute positioning was terminated because
JOB 9 was initiated (only at incremental
encoders)
Direction of rotation of the drive and the
encoder varies
What to Do
Check the load voltage (2L+) at
terminal 7
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
