Approach Speed
Setting
(Napr)
OWC00A
0 to 32767
(Default = 0)
The unit will vary with the speed reference selec-
tion (OBC001D).
When the speed reference value selection = 0.
1 = 10
n
reference units/min
(n = Number of digits below decimal)
Pulse unit: 1 = 1,000 pulses/min
(PO-01: 1 = 100 pulses/min.)
mm unit: 1 = 1 mm/min
deg unit: 1 = 1 deg/min
inch unit: 1 = 1inch/min
When the speed reference value selection = 1.
1 = 0.01% (1000 = 10.00%)
