Inching: 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
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 Inching: DIR_P and DIR_M = 1
13 Direction of rotation of the drive and the
encoder varies
Check the wiring of the drive and the encoder
as well as the parameter for the reversal of the
direction of rotation and adapting the direction
of the drive.
Voltage for inching >32 511 or < 0
