Signals from axis/spindle
DB31, ... DBX61.0 (drive test travel request)
If machine axes are traversed by special test functions such as "function generator", an explicit drive-test-specific
enable is requested for the movement:
DB31, ... DBX61.0 == 1 (drive test travel request)
The movement is carried out once the movement is enabled:
DB31, ... DBX1.0 == 1 (drive test travel enable)
DB31, ... DBX61.3 (follow-up mode active)
The machine axis is in follow-up mode.
DB31, ... DBX61.4 (axis/spindle stationary (n < n
min
)
"Axis/spindle stationary" is set by the NC if:
• No new setpoints are to be output AND
• The actual speed of the machine axis is lower than the parameterized zero speed:
MD36060 $MA_STANDSTILL_VELO_TOL (threshold velocity axis stationary)
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 (parameter set servo)
Active parameter set Coding accordingly:
DB31, ... DBX9.0 / 9.1 / 9.2 (controller parameter set selection)
