Position data can be shifted by the value set in this
register.
The parameter is valid during RUN operation, but
set it while the system is OFF.
This register contains data used by MP940 Mod-
ules for position control and the following move-
ments are affected if this register is set incorrectly.
Check to see if the data is set correctly prior to
starting operation.
Obstructions may damage tools and lead to per-

Approach Speed
Setting (Napr)
OWC00A
0 to 32767
Set the approach and creep speed when returning to
the zero point (ZRET).
The setting unit depends on OBC001D: Speed Ref-
erence Selection.
1. When OBC001D = 0 (specified in reference
units)
1 = 10
n
reference units/min (n = number of dig-
its below the decimal point)
Pulse unit: 1 = 1000 pulses/min
mm unit: 1 = 1 mm/min
deg unit: 1 = 1 deg/min
Inch unit: 1 = 1 inch/min
2. When OBC001D = 1 (% specified), then 1 =
0.01% (percentage of the rated rotation speed).
Note: A percentage is specified regardless of the
setting at OBC01D in Zero Point Return
Mode.
