Leadscrew error compensation with rotary axes in NC machine data “Distance between 2 values” has been
entered for the appropriate axis with a value which cannot be divided into 360 degrees to give an integer, i.e. grid
spacing is not equal; e.g.
S Correct: NC–MD= 10 (rotary axis)
S Results in: 360/10 = 36 grid points
S Incorrect: NC–MD= 11
S Would give: 360/11 = 32,7 grid points
The compensation value chosen is too large compared with the distance between two leadscrew error compensa-
tion points (valid for rotary and linear axes).
Modify NC machine data “Distance between 2 values” – check NC MD 324* and 328*.
S The compensation value in NC MD 328* must be less than NC MD 324*.
104* Speed setpoint value warning limit responded Reset key
S Cyclic
S Interlocking of NC START
For analog measuring circuit:
The DAC set value entered is higher than in NC machine data 268* “Maximum setpoint speed (DAC)”. It is not
possible to increase the set value further.
S Traverse more slowly
S Check actual values (encoder)
S Check NC machine data “Maximum setpoint speed (DAC)”
S Check the drive actuator

S Interlocking of NC START

S Setpoint 0
S The control enable is removed after the time stored in NC machine data “Control enable cutout delay” has
elapsed
S Follow-up operation
S The following error could not be cleared faster than the time entered in NC machine data “Control enable
cutout delay” during positioning
S On clamping, the limit defined in NC machine data “Zero speed monitoring” was exceeded
S A mechanically clamped axis has been pushed out of position
S Fault in the control device (actuator), at the tacho, at the motor, in the CNC measuring circuit hardware or
at/on the pulse encoder
S Incorrect specification on assigning the set value output
S At start-up: wrong position control direction
S NC machine data “Zero speed monitoring” must be greater than “Coarse exact positioning limit”
S NC machine data “Control enable cutout delay” must be large enough for the following error to be removed
within this time (only applies if NC machine data “Zero speed monitoring delay” = 0)
S NC machine data “Zero speed monitoring delay” must be large enough for the following error of the individual
axis to be removed within the time entered
S Check actual values (encoder) and position control direction
