DB31, ... DBX9.3 (disable parameter-set default setting by NC)
Parameter-set changeover request will be ignored.
2.1.8 Signals from axis/spindle
DB31, ... DBX61.0 (travel request)
The machine axis is to be traversed, e.g., by means of a part-program instruction or
manually. The NC sends the travel request to the PLC. On the basis of the travel request,
the PLC user program can then cancel the clamping of the axis, for example, and set the
"servo enable".
DB31, ... DBX61.3 (follow-up mode active)
The machine axis is in follow-up mode.
DB31, ... DBX61.4 (axis/spindle stationary)
"Axis/spindle stationary" is set by the NC if:
• No new setpoints are to be output AND
• The actual velocity of the machine axis is less than the assigned standstill velocity:
MD36060 $MA_STANDSTILL_VELO_TOL (threshold velocity axis stopped)
DB31, ... DBX61.5 (position controller active)
The machine axis position control loop is closed and position control is active.
DB31, ... DBX61.6 (speed controller active)
The machine axis speed control loop is closed and speed control is active.
DB31, ... DBX61.7 (current controller active)
The machine axis current control loop is closed and current control is active.
DB31, ...DBX69.0 / 69.1 / 69.2 (controller parameter set)
Active parameter set Coding accordingly:
DB31, ... DBX9.0 / 9.1 / 9.2 (controller parameter set selection)
