D In the normal speed control mode (including when the soft start/stop
function is used), this function overrides speed, with analog voltage
input from an external unit to the spindle amplifier.
D The override function with analog input voltage is enabled when this
signal is set to 1 in the normal speed control mode (including when the
soft start/stop function is used).
D A limit (100% or 120%) of this function should be assigned to the
following parameters:
FS0 FS15 FS16 Contents of parameter
6506#5 3006#5 4006#5 Setting of input range of spindle
analog override:
0 : 0 to 100%
1 : 0 to 120%
The maximum analog input voltage is +4.5 V. If an override speed
exceeds the maximum speed, it is clamped by the maximum speed.
D An override type is specified using the following parameter.
FS0 FS15 FS16 Contents of parameter
6506#6 3009#5 4009#6 Override type setting
0 : Linear function type
1 : Quadratic function type
Linear function type override
An actual override value corresponds to the entered override
value on a one–to–one basis.
OVR

= OVR
IN
Quadratic function type override
An actual override value corresponds to the entered override
value on the quadratic function basis. The speed resolution of
quadratic function type override is low in a high speed range and
high in a low speed range, as compared with that of linear
function type override.
