[ a ] Speed Reference Parameter Setting Examples (1)

No. 5 = 3 digits
No. 34 = 3,000 min

−1

No. 36 = 65,536 pulses/rotation

Therefore, rated speed = 3,000 min

–1

= 3000 × 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 [pulse] ÷ 60

= 1638400 [pulse/s]

OW††18 = 10000 (100%)

b)Command Unit = mm (1 reference unit = 0.001 mm)

For a feed speed of 500 mm/s with a machine that travels 10 mm for each rotation
with the above settings:

OL††10 = 500000 (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

× 65,536 [pulse] ÷ 1,000

= 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 settings:
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%)
