2.1.10 Signals from axis/spindle (digital drives)
DB31, ... DBX92.0 (setup mode active)
On the drive, "setup mode" is active.
DB31, ... DBX92.1 (ramp-function-generator fast stop active) (not on 810D)
The drive signals back to the PLC that ramp-function-generator fast stop is active. The drive
is thus brought to a standstill without the ramp function (with speed setpoint 0).
DB31, ... DBX92.2 (torque limit 2 active) (not on 810D)
The drive signals back to the PLC that torque limit 2 is active for the axis/spindle. The torque
limit value is defined with the drive parameters.
DB31, ... DBX92.3 (speed-setpoint smoothing active) (not on 810D)
The PLC user program requests speed-setpoint smoothing filter for the axis/spindle. The
smoothing is activated in the drive module only under certain conditions.
DB31, ... DBX93.0, 1, 2 (active drive parameter set A, B, C)
The drive module sends this checkback to the PLC to indicate which drive parameter set is
currently active. With bit combination A, B, C, eight different drive parameter sets can be
selected by the PLC for the SIMODRIVE 611D.
