6.1 Support Functions for Controlled Axes
6 -5
Parameter
No.
Default Description Name
21 Gear ratio, load end Setting example 1
m (Servomotor
shaft rotations)
7 rotations
n (load shaft rotations)
4 rotations
9 rotations
3 rotations
In the preceding diagram: Deceleration ratio: n/m = 3/7 ¢ 4/9 = 4/21
Consequently, set the gear ratio (Servomotor end) at 21 and the gear ratio (load
end) at 4.
6.1.3 Override Function
When an axis is moving via rapid traverse or interpolation feed for example, the speed of move-
ment can be changed by setting a percentage (override percentage) with respect to the specified
speed.
D The procedure used to set override is different in rapid traverse and interpolation systems.
Rapid traverse JOG
STEP
Rapid traverse (MOV)
By axis:
Override enabled/disabled (fixed parameter 17 b9)
Override (setting parameter OWxx2C)
Interpolation Linear interpolation
(MVS)
Circular interpolation
(MCW/MCC)
Skip (SKP) Set in a group definition by each group. The default
setting is MW00001. This override is always enabled.
MW00001 (100 % = 10000)
D An override in the range of 0% to 327.67% can be selected for the Rapid Traverse Speed.
Set Override (OWxx2C) in the setting parameter for each axis.
z Override
Override often means “to invalidate.” In this manual, however, it should be taken to mean “change” the set value.
