When cyclic second pitch error compensation is used at the same time,
the pitch error compensation amount is output in interpolated form in
each cyclic second pitch error compensation point interval.
If the feedrate is high, multiple compensation pulses may be output at
the same time. The minimum interval in which multiple compensation
pulses are not output at the same time is determined with the following
formula. The compensation point interval must be larger than the
distance calculated with the following formula.
Minimum pitch error compensation point interval
= (Fmax/7500)×(Pmax+1)
where
Fmax : Maximum feedrate
Pmax : Maximum pitch error compensation amount
Example)
If the maximum feedrate is 15000 mm/min and the maximum
pitch error compensation amount is equal to seven pulses, the
minimum compensation interval is 16 mm.
