Override
Analog override
Analog override can be used with the point table method and indexer method.
To use the analog override function, set "Override selection" in [Pr. PT38] to "2".
When using analog override in the point table method or indexer method, enable bit 7 (C_OVR) of Control DI7
(2D07h).
The following shows the functions in which analog override can be used.
• Point table mode (pt)/Indexer mode (idx)
• Jog mode (jg)
• Home position return mode (hm) in point table method/indexer method
• Automatic positioning to home position function in point table mode (pt)
The following shows the functions in which analog override cannot be used.
• Test operation mode in MR Configurator2 (Positioning operation/jog operation)
If the servo motor speed changed by the analog override value exceeds the maximum speed of the servo
motor, the servo motor speed is limited by the maximum speed of the servo motor.
The servo motor speed can be changed with Override (2DB0h). The following table lists the objects related to analog override.
Use bit 7 of Control DI7 (2D07h) to select the change value.

Bit 7 of Control DI7 (2D07h)
Setting bit 7 of Control DI7 (2D07h) to on enables the analog override
setting.
