The override operation is used to change the speed of an active axis. While
the Override Enable Bit is ON, the target speed is changed by applying the
override value that is set in the Axis Operating Output Memory Area.
The override can be set from 0.01% to 327.67% in units of 0.01%. The speed
command values (Speed command value for speed control in speed control
mode) set for direct operation, origin return, jogging, and speed control opera-
tions are taken to be 100%.
The override function is disabled during origin search or torque control.
The target speed when override is enabled is as follows:
3E8 hex (1000)
1000
5DC hex (1500)
