NCK alarm with processing stop present (DB3300.DBX4.7)
The control sends this signal to the PLC to indicate that at least one NCK alarm, which has interrupted or aborted the current
program run (processing stop), is active for the channel.
Follow-up active (DB390x.DBX1.3)
Follow-up mode for this axis is active.
See Section: Signals from PLC to NCK, follow-up mode (Page 13) (DB380x.DBX1.4)
Axis/spindle stationary (DB390x.DBX1.4)
The current velocity of the axis or actual speed of the spindle is within the range which is defined as standstill. This range is
defined with MD36060 STANDSTILL_VELO_TOL (maximum velocity/speed for signal "Axis/spindle stationary").
Position control active (DB390x.DBX1.5)
The position control loop for the axis/spindle is closed; the position control function is active.
For details, see Controller enable (Page 13).
Speed control active (DB390x.DBX1.6)
The speed control loop for the axis/spindle is closed; the speed control function is active.
For details, see Controller enable (Page 13).
Current control active (DB390x.DBX1.7)
The current control loop for the axis/spindle is closed; the current control function is active.
Lubrication pulse (DB390x.DBX1002.0)
The IS "Lubrication pulse" is sent by the NCK and
once the axis/spindle has traveled a greater distance than
that set in MD33050 LUBRICATION_DIST (travel distance for lubrication from PLC)
Signals for digital drives, from axis/spindle
Drive ready (DB390x.DBX4001.5)
Checkback signal indicating that the drive is ready. The conditions required for traversing the axis/spindle are fulfilled.
Integrator for n-controller disabled (DB390x.DBX4001.6)
The speed-controller integrator is disabled. The speed controller has thus been switched from PI to P controller.
Pulse enabled (DB390x.DBX4001.7)
The pulse enable for the drive module is available. The axis/spindle can now be traversed.
Ramp-up procedure completed (DB390x.DBX4002.2)
This signal confirms that the actual speed value has reached the new setpoint allowing for the tolerance band set in the drive.
The ramp-up procedure is thus completed. Any subsequent speed fluctuations due to load changes will not affect the
interface signal.
Signals from PLC to HMI
OP key disable (DB1900.DBX5000.2)
IS "OP key disable" can be applied to disable (1 signal) or enable (0 signal) the connected keyboard.
Program number (DB1700.DBB1000)
A declared program number is transferred from the PLC to HMI if an NC program is selected by the PLC. The current NC
program selected can be stored via the command interface (see DB1700.DBB1001) and also selected again.
