(5) Analog override
You can change the servo motor speed by using OVC (Analog override). The following table shows
signals and parameters related to the analog override.
Analog input signal
Contact input signal
Parameter
(a) OVC (Analog override)
You can continuously set changed values from outside by applying voltage (-10 to +10 V) to OVC
(Analog override). The following shows percentage of the actual speed to input voltage and set
speed.
OVC (Analog override) applied voltage
POINT
To use OVC (analog override), set [Pr. Po11] to "_ _ 1 _".
The override function has two types. One is analog override by using analog
voltage input and another is digital override by using parameter settings.
Analog override target method: Point table method/program method
Digital override target method: Indexer method
OVR (Analog override selection) is for the analog override. The digital override
does not depend on OVR (Analog override selection).
Refer to [Pr. PT38], [Pr. PT42], and [Pr. PT43] for the digital override.
When using the analog override in the point table method or program method,
enable OVR (Analog override selection).
The following shows usable functions and non-usable functions.
(1) Analog override usable
Automatic operation mode (point table method/program method)
JOG operation in the manual operation mode
Automatic positioning to home position function in the point table method
(2) Analog override unusable
Manual pulse generator operation in the manual operation mode
Home position return mode
Test operation mode using MR Configurator2 (positioning operation/JOG
operation)
