The screw pitch compensation points are distributed in equal interval, and the interval value of
each axis is set respectively. The minimum value of the interval is limited and set by the following
formula: the minimum value = the maximum feedrate (rapid feedrate) / 7500.
Unit: Screw pitch compensation minimum interval: mm, inch and deg.
Maximum feedrate: mm/min, inch/min and deg/min.
For example: When the maximum feedrate is 15000mm/min, the minimum value of the screw
pitch error compensation interval is 2mm.
But, according to the setting override, when the absolute value of the compensation point value
exceeds 100, the interval of the compensation point is magnified by the override which is calculated
by the following formula.
Override = Max compensation amount (absolute value)/128 (round up the digits after the decimal
point)
Screw pitch compensation minimum interval = Value, which is obtained from the above maximum
feedrate X override.
Note: The unit of the screw pitch compensation value is same as that of the detection.
The detection unit is relative with parameter No.1820 (command magnify ratio CMR) and the
minimum movement unit, about the relation between the setting units and the minimum movement
units, refer to the introduction of parameter No.1820.
