The operating mode selected is not allowed.
Select an allowed operating mode
In the "Jogging" and "Control" operating modes, the selected ve-
locity or control level is not 1 or 2. In incremental operation the set
value number is not allowed (1 - 100, and 254 permitted).
Set operating mode parameters to an allowable value.
A travel command was given in the absence of a start enable
(start, external start, R+/R–)
Restore travel command and wait for start enable
Synchronization of the axes is necessary in the "Incremental, rela-
tive," "MDI" and "Automatic" operating modes.
Execute reference point approach
In operating modes "Jog," "Control" or "Incremental, relative"
the direction settings R+/R- are active at the same time. With "Ref-
erence point operation" the direction setting no longer
agrees with the startup direction specified in the MD.
Correct the direction parameters
