The existing axis-specific feedrate override or spindle override is not active.
If the feedrate override is inactive, "100%" is used as the internal override
factor.
Note:
The 1st switch position of the gray-coded interface for the value is an
exception. Also here, for "Override inactive", the override factor of the 1st
switch position is used and for axes, 0% is output as override value (acts the
same as "Feedrate disable"); correspondingly 50% for the spindle.
•
The spindle override is always accepted with 100% in the spindle
"Oscillation mode".
•
The spindle override acts on the programmed values before limits (e.g.
G26) intervene.
•
The feedrate override is inactive when G33 is active.

Function Manual Basic Functions V1
Controller enable
Signal(s) to axis / spindle (PLC → NCK)
Signal(s) updated: Cyclic
The position control loop of the axis / spindle is closed; the axis / spindle is
in closed-loop control.
When "controller enable" is set by the PLC user program:
•
Position control loop of axis is closed.
•
Position actual value is no longer switched to the position setpoint.
•
The controller enable of the drive is output.
• The interface signal:
DB390x DBX1.5 (position controller active)
is set to a 1 signal.
When "controller enable" has been issued no new actual value
synchronization of the axis (reference point approach) of the axis is
necessary if the maximum permissible limit frequency of the axis measuring
system has not been exceeded during follow-up mode.
As a function of the interface signal:
DB380x DBX1.4 (follow-up mode)
it is possible to select whether or not the axis first traverses back to the
earlier setpoint position (i.e. the positional deviation caused by the clamping
process is moved through to eliminate the deviation).
