enable
... enables movement.
When the signal is reset, a deceleration of the movement takes
place.
If MD 37.15 = 0, program execution or the movement is aborted and
the distance to go deleted.
If MD 37.15 = 1, the following applies (machining resumed after
emergency stop):
S Rapid deceleration of the movement.
S On axis standstill FR+ or FR− = 0; BL = 1
the drive remains activated and Servo Enable active
S If an error occurs in this state (e.g. the user starts the movement
without a Start Enable, etc.), the relevant error response is initi-
ated, e.g. the distance to go is deleted; BL = 0 (a new path must
be specified).

... selects speed levels in Jogging mode
... selects frequency levels in Control mode
... selects increment in Incremental relative mode (value 1 − 100 or
254).
OVERRIDE OVERR Override ... affects response of traversing movement. Range: 0-255%
... override has no effect in Control mode
S Velocity override
Range: 0-255%
Speed adjusted by percentage
Example: Override doubled from 100% to 200%
− speed v is doubled
− acceleration and deceleration values are not affected
