Parameter Setting Examples
1. Speed Reference Value Selection Set to “0”
a) Pulses Selected as the Unit
When you wish to perform operations with the fixed parameters set for a rapid
traverse speed of 1,500 r/min, an approach speed of 300 r/min, and a creep speed of
150 r/min, use the following settings.
• OWC00A = 300 (r/min) 2048 4 (ppr) 1000 = 2457 (= 2457000 ppm)
• OWC00B = 150 (r/min) 2048 4 (ppr) 1000 = 1228 (= 1228000 ppm)
• OWC015 = --- (Invalid)
• OLC022 = 1500 (r/min) 2048 4 (ppr) 1000 = 12288 (= 12288000 ppm)
• OWC02C = 10000 (100%)
b) Millimeters Selected as the Unit
When you wish to perform operations with the fixed parameters set for a rapid
traverse speed of 900 mm/min, an approach speed of 180 mm/min, and a creep speed
of 90 mm/min in a machine configuration that moves the axis 10 mm in one rotation,
use the following settings
• OWC00A = 180
• OWC00B = 90
• OWC015 = --- (Invalid)
• OLC022 = 900
• OWC02C = 10000 (100%)
2. Speed Reference Value Selection Set to “1”
When you wish perform operations with the fixed parameters set for a rapid traverse
speed of 1,500 r/min, an approach speed of 300 r/min, and a creep speed of 150 r/min,
use the following settings
•
•
•
• OLC022 = --- (Invalid)
• OWC02C = 10000 (100%)
3. When you wish to leave the above speed reference settings unchanged, but halve the
operating speed, use the following setting.
• OWC02C = 5000 (50.00%)
