(a) Speed Reference Parameter Setting Examples
EXAMPLE
No. 5 = 3 digits
No. 34 = 3,000 min
No. 36 = 65,536 pulses/rotation
Therefore, rated speed = 3,000 min
= 3,000 × 65,536
= 196,608,000 ppm
1. Speed Unit Set to 0 (reference units/s)
a) Command Unit = Pulses
For a feed speed of 1,500 min
OL
OW
b) Command Unit = mm (1 reference unit = 0.001 mm)
For a feed speed of 900 mm/s with a machine that travels 10 mm for each rotation with the above set-
tings:
OL 10 = 900000 (reference units/s)
OW 18 = 10000 (100%)
2. Speed Unit set to 1 (10
a) Command Unit = Pulses
For a feed speed of 1500 min
OL 10 = 1,500 [min
= 98304 [1,000 pulses/min]
OW 18 = 10000 (100%)
b) Command Unit = mm
For a feed speed of 900 mm/s with a machine that travels 10 mm for each rotation with the above set-
tings:
OL 10 = 900
OW 18 = 10000 (100%)
3. Speed Unit set to 2 (percentage)
For a feed speed of 1,500 min
1,500 [min
OLxx10 =
3,000 [min
= 5,000
OW 18 = 10000 (100%)
