Index of the position offset group
Description	A position offset defines an additional offset allowing, for instance, differing clamping positions of a workpiece in the working area of a machine to be taken into consideration. Position offsets are defined in the position of offset data. The position offsets for each axis are specified within a position offset group. Selection of a position offset group is performed based on the index of the group. The data of the position offsets is evaluated by the CNC at the start of the program.

In the current operation mode the channel can be stopped by a FEEDHOLD or by a MCM-STOP-command (see States graph of the operating modes). In both cases the operation mode shows the state HOLD.

Otherwise after a stop the channel can be continued by removing the FEEDHOLD or by a MCM-RESUME.

This means the signals FEEDHOLD or MCM-STOP can be used symmetrical. A MCM-STOP internal creates a FEEDHOLD. This means, the PLC must provide the feedhold-control unit to push the MCM-STOP-command.

Emergency stop
Description	If this element is set active (TRUE) for emergency stop, interpolation is aborted immediately by output of the zero setpoint or by a deceleration in accordance with emergency deceleration. The NC kernel reverts to Error state. This type of movement influencing has maximum priority.

Single-Block mode
Description	Activating/deactivating Single-Block mode. Single-Block mode refers only to motion blocks. For as long as Single-Block mode is activated, the system is decelerated to feed rate = 0 at the end of each motion block. The following blocks can then be executed only by setting element continue motion if all axes are in the control window. The next NC block is then executed with each leading edge of the signal.

Optional stop
Description	Activating/deactivating optional stop. If function M01 (optional stop) is programmed in the current block of the NC program, setting this element to value TRUE allows a stop at the end of the block (ramped deceleration in accordance with the permitted accelerations). The following block can be enabled by activating element Continue Machining if the NC kernel indicates that all axes are in the control window by resetting status flag X_WaitAxesInPosition.

Description	If the value of element Continue Motion is set to TRUE, program execution interrupted by selection of Single-Block mode and/or Optional stop and/or by M00 in the NC program is resumed. The precondition for this is that all axes be in the control window. An NC block is executed with each leading edge at this input.

Characteristics
Parameterization/ mode of operation	The rapid feed override is only active, if this function is also activated in the channel parameters list. Otherwise, there is made no distinction between feed and rapid feed blocks. The several modes can be set by the channel parameter P-CHAN-00181: The rapid feed override is not active. The feed override effects on feed and rapid feed blocks. The rapid feed override is active. In feed blocks the feed override is active, in rapid feed blocks the minimum of feed and rapid feed override is active. The rapid feed override is active. In feed blocks the feed override is active and in rapid feed blocks only the rapid feed override is active.

Acceleration override

Interrupt output of command values on real axes
Description	The output of command values of the NC-channel on physical axes is interrupted. The NC-channel is stopped and the assignment to the real axes is disabled. After that the physical axes can be requested and moved by another channel. During this a different logical axis can be assigned to a physical axis. After removing this interruption the axes can be requested again and the original channel can continue with movement.
