Servo Drive for Linear mover

**

With this kind of a drive for the linear mover you can specify a number of positions on the edit mask. At runtime these positions can be selected by the PLC by their numbers.

The number of the target has to be assigned to a word of the PLC. If you have selected the option bit-coded the position of the least significant bit will be used as number in word.

The new target will be activated when the bit ‘start/enable’ has a rising slope or immediately if the appropriate check box ‘always 1’ is clicked. Even if you specify a bit you will be able to configurate that each setpoint changing is taken over immediately (without rising slope as well): activate the check box ‘immediately’ for doing this.

The servo drive will only run if the bit ‘start/enable’ is waiting or if the check box ‘always 1’ is clicked.

By the bit ‘position reached’ the servo drive will report if it remains under the distance to the target position that you have specified.

The position is headed for with the specified maximum speed by start- and stop-slopes. The steepness of the slope you do not specify by a time but by the distance after that the drive shall have the maximum speed resp. at which distance to the target it shall be started braking (while stopping). If you create the slope too small the drive will not be able to stop with control. This is not that different in reality and that is why we did not take great trouble to get rid of this effect. You can modify the speed as well as the slope by the PLC program by the help of a poke.

With ‘Shift+Ins’ and ‘Ctrl+Ins’ you can insert new lines in the table of the positions. With ‘Shift+Del’, ‘Ctrl+Del’ and ‘Ctrl+X’ you can delete lines. Take care to modify the target numbers in the PLC if you change the numbering by inserting or deleting positions.

With the button ‘teach’ you can take over the current position of the linear mover. Adjust this position with the slide controller ‘hot spot’ on the edit mask of the linear mover before.

You can specify the set position of the hot spot directly by the PLC as well.
