(e.g. X) (see «Operator Manual»).
The axis must be moved at low speed (10 percent VMAX).

Improving the Settings
REMARK: For each axis to be checked, change the axis name and speed in the above program.

Check following for the axis in movement on the «AXIS» page in the
«ERROR» column.
The value must be:
EMAX (in internal measurement units or deg/10000) = VMAX x Τ x 11/10/k
REMARK: In case of tachometer asymmetry or incorrect adjustment of the servo-drive, the
value may not be the same in both directions.
