CAUTION
Stop command to CNC is not executed.
Possible damage to machine.
Similar to other control units, a command from an external application, e.g. an HMI, is indicated in request_r. If the PLC operates this control unit and therefore set enable_w to TRUE, the command from the external application only becomes effective when request_r is written to command_w. Here the semaphores must be operated as usual.
This must also be considered if the PLC operates the control unit in order to switch operation modes (see section 8.2) and therefore sets the enable_w to TRUE A HOLD command sent by this control unit triggers the NC kernel to send a request to activate feedhold. This is again indicated in request_r of the control unit described here and only becomes effective when the PLC copies PLC request_r to command_w. This also applies to cancelling feedhold.
The figures below depict these functions.
Feedhold ON/OFF type 2 | |
Description | When this element is set to TRUE, the feed rate is immediately ramped down to feed rate = 0 during interpolation. |
Data type | MC_CONTROL_BOOL_UNIT, see description Control Unit |

Single-block mode | |
Description | Activating/deactivating single-block mode. Single-block mode refers only to motion blocks.

The following blocks can then only be executed by setting the element “continue motion” if all axes are located in the control window. |

If the function M01 (optional stop) is programmed in the current block of the NC program, set this element to the value TRUE to stop at block end (ramped-down deceleration complying with the permissible accelerations). The following block can be enabled by activating the element “continue machining” if the NC kernel indicates that all axes are located within the control window by resetting the status flag wait_axes_in_position_r. |

Resumption of motion | |
Description | If program execution is interrupted by selecting "Single block mode" or"Optional stop" or by M00, this control unit can resume NC program execution. A falling edge for the command value (command_w) of the control unit "Continue motion", i.e. a transition from TRUE to FALSE, leads to a resumption of NC program execution. The condition for this is that all axes are located in the control window. |

Parameterisation/ mode of operation | Rapid traverse override is only active if this function is also activated in the channel parameter list. Otherwise, there is no distinction made between feed and rapid traverse blocks. Setting options in the channel parameter P-CHAN-00181: Rapid traversing override is inactive. Rapid traversing override acts on feed and rapid traversing blocks. Rapid traversing override is active. Feed override acts on feed blocks and the minimum of feed and rapid traversing override acts on rapid traversing blocks. Rapid traversing override is active. Feed override acts on feed blocks and only rapid traversing override acts on rapid traversing blocks. |
Interrupt output of command values to real axes | |
Description | This interrupts the output of NC channel command values to physical axes. The NC channel is stopped and assignment to the real axes is disabled. Physical axes can then be requested and moved by another channel. A different logical axis can be linked to a physical axis here. After clearing this interruption, the axes can be requested again and the original channel continues its motion. |

If the #STOP REVERSIBLE [LEVEL=<bitmask>] is programmed in the current block in the NC program,<bitmask>the program stops at block end (ramped deceleration based on the permitted deceleration values) if the same value assigned to the LEVEL option in the NC program is already sent by this control unit to the MOTION Controller thus activating the STOP instruction. The next block is enabled by a control unit command "Continue motion" (continue_motion) if the NC kernel displays that all axes are located in the control window by resetting the status display "Wait for axis group in position" (wait_axes_in_position_r). |
