Precautions are classified into Warning and Caution according to their bearing on safety. Also, supplementary information is described as a Note. [. . . ] If the magnification is set to 1, the same unit as the detection unit is used for the compensation data. If 0 is set, the same magnification selected by setting 1 is selected. Interval between pitch error compensation positions for each axis 3624 NOTE When this parameter is set, the power must be turned off before operation is continued.

The space between two adjacent positions is set for each axis. The minimum interval between pitch error compensation positions is limited and obtained from the following equation: Minimum interval between pitch error compensation positions = maximum feedrate (rapid traverse rate)/7500 Units: Minimum interval between pitch error compensation positions: mm, inch, deg Maximum feedrate: mm/min, inch/min, deg/min Example: When the maximum feedrate is 15000 mm/min, the minimum interval between pitch error compensation positions is 2 mm. If setting a magnification causes the absolute value of the compensation amount at a compensation position to exceed 100, enlarge the interval between the compensation positions by using a multiple calculated as follows: Multiple = maximum compensation amount (absolute value)/128 (Round the remainder up to the nearest integer. ) Minimum interval between pitch error compensation positions = Value obtained from the above maximum feedrate × multiple For linear axis · Machine stroke: -400 mm to + 800 mm - 180 - B-64120EN/01 4. DESCRIPTION OF PARAMETERS · Interval between the pitch error compensation positions: 50 mm · No. of the compensation position of the reference position: 40 If the above is specified, the No. of the farthest compensation point in the negative direction is as follows: No. of the compensation position of the reference position (Machine stroke length in the negative direction/Interval between the compensation points) + 1 = 40 - 400/50 + 1 =33 No. of the farthest compensation position in the positive direction is as follows: No. of the compensation position of the reference position + (Machine stroke length in the positive direction/Interval between the compensation positions) = 40 + 800/50 = 56 The correspondence between the machine coordinate and the compensation position No. is as follows: Machine coordinate (mm) -400 -350 -100 -50 0 50 100 750 800 Compensation point No. 33 39 40 41 42 56 Compensation values are output at the positions indicated by f. Therefore, set the parameters as follows: Parameter No. 3620: Compensation point number for reference position No. 3621: Compensation point number for farthest point in the negative direction No. 3622: Compensation point number for farthest point in the positive direction No. 3624: Compensation point interval Setting 40 33 56 1 50000 The compensation value is output at the compensation position No. corresponding to each section between the coordinates.
