(a) Speed Reference Parameter Setting Examples
No. 5 = 3 digits
No. 34 = 3,000 min
-1
No. 36 = 65,536 pulses/rotation
Therefore, rated speed = 3,000 min
-1
= 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
-1
with the above settings:
OL

10 = 1,500 [min
-1
]
×
65,536 [pulses]
÷
60
= 1638400 [pulses/s]
OW

18 = 10000 (100%)
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

reference units/min)
a) Command Unit = Pulses
For a feed speed of 1500 min
-1
with the above settings:
OL

10 = 1,500 [min

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
with the above settings:
.
OW

18 = 10000 (100%)
4. To leave the setting of Speed Reference (OL

10) unchanged and reduce the operating speed to half
(50%):
OW

18 = 5000 (50.00%)
