RETURN TO REFERENCE
POINT
The Cs coordinate setup function was sus-
pended. Make a manual reference position
return.
1. An attempt was made to perform Cs axis
coordinate setup for the Cs axis for which
CSPEN = ’0’.
2. No position information has been trans-
ferred from the spindle amplifier.
3. The machine was brought to an emergen-
cy stop during coordinate setup.
4. Cs axis coordinate setup was started for
the Cs axis for which bidirectional pitch er-
ror compensation was in effect.
5. Cs axis coordinate setup was started for
the Cs axis whose servo was off.
If the CMR is greater than 1 (parameter No. 1820 > 2), the Cs axis may
move through several pulses’ worth of distance. This is intended to align
the Cs axis machine position to the least command increment. (1 to 9
pulses in terms of detection units if CMR = 10.)
If the Cs axis machine position meets the following condition, the Cs axis
moves by a pitch error compensation during coordinate setup.

Pitch error compensation
Assuming that a pitch error compensation of +0.004 is specified for a
pitch error compensation interval of 10.000 degrees and a machine
coordinate of 5.000, the Cs axis will not stop at a machine position of
5.000 to 5.003.
Machine coordinate 4.999 → 5.000 → 5.001
Machine position 4.999 → 5.004 → 5.005
