11-7 Override
Override is used to change the speed of axis startup.
[1] Outline of function
While override enable is ON, the override set to the operation data area is captured to change the
target speed.
An override within the range 1 to 999% is valid. The target speed set in program operation, direct
operation and jog operation is set as 100%.
Target speed = Specified speed ×

An override applied on pulse output during a zero return is invalid. Note, however, that when origin
compensation is set to ON, override on the compensation data worth of pulse output is valid.
• "0%" cannot be specified for the override. When "0%" is specified, the override is enabled, and
pulse output stops.
• Operation is performed at the maximum speed when the maximum speed (parameter 1 address
A+0014 to 0017) is exceeded by an override.

• "****" in N+**** indicates the numerical value of the address.
