... enables movement.
When the signal is reset, a rapid deceleration of the movement takes place.
On MD 37.15 = 0 program execution, or the movement, is canceled and the
residual distance is deleted.
On MD 37.15 = 1 machining resumes after emergency stop
Rapid deceleration of the movement.
On axis standstill FR+ or FR– = 0; BL = 1
–
if the drive remains activated and the servo enable active, the axis is
held in position control mode.
–
if the drive is deactivated, the user must activate "follow-up". This
deactivates zero speed control (the axis can be pushed away).
If an error occurs in this state (e.g. if the user starts a movement without a
start enable, etc.), an error response is initiated, e.g. the residual distance
is deleted, BL = 0, (a new path default must be defined).

... selects speed levels in Jogging mode.
... selects voltage/frequency levels in open-loop control mode.
... selects increment in Incremental relative mode (value 1...100 or 254).
... affects response of traversing movement. Range: 0-255%
... override has no effect in Control mode
Velocity override
Range: 0-255%
Speed adjusted by percentage
Example: Override doubled from 100% to 200%
