No. Message Meaning
5046 ILLEGAL PARAMETER(ST. COMP) The parameter for setting slope compensation is
incorrect. This alarm occurs in the following case:
!
Invalid axis numbers have been assigned to move
or compensation axes.
!
Parameter (No.13381-No.13386) is incorrect.
5321 S-COMP. VALUE OVERFLOW
!
The value set for straightness compensation has
exceeded maximum value 32767. Do not fail to
perform reference point return manually after
generating this alarm.

- This function is an option function.
- S-RAM 768byte is necessary to use this function
- Stored pitch error compensation option is necessary to use this function.
- If the feedrate is high, multiple compensation pulses may be output at the same time
depending on the straightness compensation amount.
- The compensation point interval is the same as that for stored pitch error compensation.
(No.3624)
- The compensation magnification can be set separately from that of stored pitch error
compensation.
- The compensation amount corresponding to a compensation point on the travel axis is
superimposed on the stored pitch error compensation data for the compensation axis.
- To use this function, the number of pitch error compensation points on the travel axis must
not exceed 128 points.
- When setting the straightness compensation parameters, turn the CNC off then back on.
(When the parameters are set, P/S000"PLEASE TURN OFF POWER" alarm is generated.)
