7. POSITIONING CONTROL
(b) Combination of millimeters and inches (2))
• If interpolation control units are millimeters, positioning is conducted using
position commands calculated from the address, travel value, positioning
speed, and electronic gear, which have been converted to millimeters
using the formula: inch set value × 25.4 = mm set value.
• If interpolation control units are inches, positioning is conducted using
position commands calculated from the address, travel value, positioning
speed, and electronic gear, which have been converted to inches using
the formula: millimeter set value ÷ 25.4 = inch set value.
(c) Discrepancy (3))
• If a discrepancy exists between interpolation control units and the control
units, the travel value and positioning speed are calculated for each axis.
a) The electronic gear converts the travel value for the axis to PULSE.
b) For axis where the units match, the electronic gear converts the
positioning speed to units of PLS /s.
Positioning is conducted using position commands calculated from
travel values converted to PULSES and speeds and electronic gear
converted to PULSE per second.
• If the interpolation control units match for two or more axes during linear
interpolation with 3-axes or more, the positioning speed is calculated
using the electronic gear for the axis with the lowest number.
