Detailed description
2.1 NC/PLC interface signals
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)
DB31, ... DBX76.0 (lubrication pulse)
Following a control POWER ON/RESET, the signal status is 0 (FALSE).
The "lubrication pulse" is inverted (edge change), as soon as the machine axis has covered
the parameterized traversing distance for lubrication:
MD33050 $MA_LUBRICATION_DIST (distance for lubrication by PLC)
2.1.9 Signals to axis/spindle (digital drives)
DB31, ... DBX20.1 (ramp-function-generator fast stop) (not on 810D)
A "fast stop" is requested for the drive. The drive is then stopped without a ramp function
(speed setpoint 0). Servo enable is maintained.
DB31, ... DBX20.2 (torque limit 2) (not on 810D)
Request for torque limit 2. The limit value is specified in the drive parameters.
DB31, ... DBX20.3 (speed setpoint smoothing) (not on 810D)
Request to smooth the speed setpoint.
DB31, ... DBX21.0 / 21.1 / 21.2 (drive parameter set selection A, B, C)
Request to change over drive parameter set:
