3.4.3 Override

POINT

When using the override (VC), make the override selection (OVR) device available.

The override (VC) may be used to change the servo motor speed. The following table lists the signals and parameter related to the override:

Item	Name		Remarks
Analog input signal	Override (VC)
Contact input signal	Override selection (OVR)	Servo Configuration Software setting required.
Parameter	No.25 override offset		999 to 999mV

(1)Override (VC)

By applying a voltage ( 10 to 10V) to the override (VC) terminal, change values can be set from outside consecutively. The following graph shows the relationship between the input voltage and the ratio of actual speed to preset speed.

Note. 0 : OFF 1 : ON

(3)Override offset (parameter No.25)

Using parameter No.25, the offset voltage can be set relative to the input voltage for the override (VC).

The setting is between 999 to 999mV.
