1. AXIS CONTROL
B-64693EN-1/01
- 66 - When the magnification is set to 1, the unit of compensation data is the same as the detection unit. When the magnification is set to 0, straightness compensation is not performed.
Alarm and message Number Message Description SV1100 S-COMP.VALUE OVERFLOW The straightness compensation has exceeded the maximum of PW1103 ILLEGAL PARAMETER (S-COMP.128) The setting of a parameter for straightness compensation at 128 PW5046 ILLEGAL PARAMETER (S-COMP) The setting of a parameter related to straightness compensation axis parameter. - The straightness compensation point numbers do not have correct magnitude relationships. - No straightness compensation point is found between the furthest pitch error compensation point in the negative region - The compensation per compensation point is either too large or too small.
Caution CAUTION 1 To use this function, stored pitch error compensation is required. 2 The number of compensation points located between the furthest compensation point in the negative region and that in the positive region on each axis of stored pitch error compensation must not exceed 128. 3 The compensation point interval is the same as that of stored pitch error compensation (parameter No. 3624). 4 The compensation magnification can be set separately from that for stored pitch error compensation. 5 Straightness compensation is superposed with the data for stored pitch error compensation before being output. 6 If the motion value is high, multiple compensation pulses may be output at a time depending on the straightness compensation. 7 After setting parameters for straightness compensation, turn off the power to the NC and then back ON for the settings to take effect. 8 Interpolated straightness compensation cannot be used at the same time as conventional straightness compensation for a single moving axis. Interpolated straightness compensation can, however, be used together with conventional straightness compensation for different moving axes.
1.3.6 Interpolated Straightness Compensation 3072 Points Overview By adding this function to the interpolated straightness compensation, the number of compensation points which can be used is expanded to 3072. The number of points which can be used for one pair of interpolated straightness compensation is also expanded to 1536. As a result, higher accurate machining can be realized for a machine tool with a long stroke that requires straightness compensation, by more exact interpolated straightness compensation. |
