Approach
Speed Setting
(Napr)
OW0A
0 to 32767
Set the approach and creep speed when returning to
the zero point (ZRET).
The setting unit depends on OB01D: Speed Ref-
erence Selection.
• When OB01D = 0 (specified in reference
units)
1 = 10
n
reference units/min (n = number of digits
below the decimal point)
Pulse unit: 1 = 100 pulses/min
mm unit: 1 = 1 mm/min
deg unit: 1 = 1 deg/min
Inch unit: 1 = 1 inch/min
• When OB01D = 1 (specified in reference
units)
When OB01D = 1 (% specified), then 1 =
0.01% (percentage of the rated rotation speed).

Linear Acceler-
ation Time Con-
stant (NACC)
OW0C
0 to 32767
Set the linear acceleration/deceleration time.
Unit: ms
Set acceleration time from 0% to 100% (rated motor
speed).
The deceleration time is the same as the acceleration
time.
