Example of calculating PC1 and PC2 setting range
To use a ball screw lead of 10mm, interpolation unit of 0.5µm and OSE104 or OSA104 motor end detector
with semi-closed loop.
The following parameters are determined by the above conditions.
SV018 (PIT) = 10, SV019 (RNG1) = 100, SV020 (RNG2) = 100, IUNIT = 2
Divide the denominator and numerator.
PIT' = 1, RGN1' = 10 (Greatest common divisor = 10)
IUNIT' = 1, RGN1'' = 5 (Greatest common divisor = 2)
Obtain the maximum value of PC1 and PC2 with the calculation expression for the semi-closed loop.
PC1' < 32767 / 1 / 1 < 32767
PC2' < 32767 / 5 < 6553
With the above calculations, the setting range for PC1 is 1 to 32767 and for PC2 is 1 to 6553.
To use a rotation table, interpolation unit of 0.5µm and OSE104 or OSA104 motor end detector with
semi-closed loop.
The following parameters are determined by the above conditions.
SV018 (PIT) = 360, SV019 (RNG1) = 100, SV020 (RNG2) = 100, IUNIT = 2
Divide the denominator and numerator.
PIT' = 18, RGN1' = 5 (Greatest common divisor = 20)
Obtain the maximum value of PC1 and PC2 with the calculation expression for the closed loop.
PC1' < 32767 / 18 / 2 < 910
PC2' < 32767 / 5 < 6553
With the above calculations, the setting range for PC1 is 1 to 910 and for PC2 is 1 to 6553.
To use a ball screw lead of 10mm, interpolation unit of 0.5µm, position loop gain of 33, OSE104 or OSA104
motor end detector with closed loop, and 1µm scale machine end detector.
The following parameters are determined by the above conditions.
SV018 (PIT) = 10, SV019 (RNG1) = 10, SV020 (RNG2) = 100, IUNIT = 2, PGN1 = 33
Divide the denominator and numerator.
RNG1' = 1, RNG2' = 10 (Greatest common divisor = 10)
C30' = 3, RNG2'' = 1 (Greatest common divisor = 10)
C30'' = 1, PGN1' = 11 (Greatest common divisor = 3)
Obtain the maximum value of PC1 and PC2 with the calculation expression for the closed loop.
PC1' < 32767 / 1 / 1 < 32767
PC2' < 32767 / 1 / 11 < 2978
With the above calculations, the setting range for PC1 is 1 to 32767 and for PC2 is 1 to 2978.
To use a ball screw lead of 10mm, interpolation unit of 0.5µm, position loop gain of 33, OSE105 or OSA105
motor end detector with closed loop, and 1µm scale machine end detector.
The following parameters are determined by the above conditions.
SV018 (PIT) = 12, SV019 (RNG1) = 12, SV020 (RNG2) = 1000, IUNIT = 2, PGN1 = 33

RNG1' = 3, RNG2' = 250 (Greatest common divisor = 4)
C30' = 3, RNG2'' = 25 (Greatest common divisor = 10)
C30'' = 1, PGN1' = 11 (Greatest common divisor = 3)
Obtain the maximum value of PC1 and PC2 with the calculation expression for the closed loop.
PC1' < 32767 / 3 / 1 < 10922
PC2' < 32767 / 25 / 11 < 119
With the above calculations, the setting range for PC1 is 1 to 10922 and for PC2 is 1 to 199.
