Siko AP05 Electronic Position Indicator

The AP05 position indicator guides the user intuitively to the correct machine setting in the case of product or format change. The optimized backlit display indicates target values and actual values straight to the point. Two LEDs show the machine operator precisely the direction whereto the adjustment is to be performed.The AP05 helps avoid wrong machine settings and enhances process safety of flexible production machines.


Wide array of position indicators for spindles and axes

Mechanical position indicators are already used on many axes or spindles to display position values. From a formal perspective, Electronic digital position indicators are a logical further development of their mechanical counterparts. Both variants of the position indicators (mechanical or electronic) belong to the product line PositionLine: Position indicators. Thanks to comparable external dimensions and the trusted attachment principle on the shaft, it only takes a few minutes to convert the mechanical spindle display to a spindle positioning system that can be programmed electronically.

Electronic-digital position indicators of the DE range

The electronic digital displays of the DE range are a sensible alternative to mechanical counters in particular in cases where no suitable gear ratios are available for the mechanical versions. Because they can be programmed at will, the user can also choose to display positive and negative display values or to work in angle mode. The programming software ProTool DE is mainly of interest in special machine construction, because it allows for parameterization of the electronic displays directly prior to assembly on adjustment spindles.

Electronic-digital position indicators of the AP range with bus interface

The electronic position indicators from the AP range also have a bus interface. In bus-controlled operation, target values and actual values can be exchanged between the individual absolute position indicators and an upstream control unit.

Fieldbus and Ethernet communication for positioning displays of the AP range

Besides the RS485 and CAN bus interfaces, additional interfaces can be realized by means of a protocol converter such as Profibus, Profinet, EtherNet/IP, EtherCAT, CC-Link, DeviceNet. Functional modules, which facilitate the configuration of the electronic displays in the programming environment of your control are available for selected interfaces and controllers.

Electronic position indicators are focused on the user

This monitored spindle adjustment offers significantly better process reliability and shortens setup times for format adjustment. At the same time, this increases machine efficiency and the viability of the production equipment. The target value is displayed directly on the axle and the correct actual value entered manually is reported back, making incorrectly set stops and tool positions a thing of the past. The overall unit is not approved until all spindle positions have been reported as correct. As a result, there is no longer any scrappage or damaged tools due to incorrectly set adjustable axles.

Also possible – linear measurement with position indicators

By the combination of spindle position display AP10 or AP05, linear measurement system AP10S or AP04S and setpoint display AP10T or AP24 you can cover all adjustment points of a machine within the framework of monitored format adjustment. The hollow shaft construction allows the spindle displays AP10 and AP05 to be attached directly to an adjustment axis. The position displays AP10S and AP04S serve as positioning systems for slide adjustments in conjunction with the linear sensor MS500H. The remote displays AP10T and AP24 can be used to specify target values for format pieces or tool change directly on the machine module concerned.

Reliably and easily readable electronic position indicators

In an industrial environment, our customers especially appreciate the precise and reliable recording of measurement values offered by the electronic position indicators. The movement of the axis is then no longer recorded using a gear, but in a touchless manner – using either a magnet or a capacitor. The magnetic measurement method is particularly robust and resilient to dirt or vibration and is suitable for use in particularly rough environments. The generous LCD display technology also allows for a clear reading of the respective position values. A typical application: The stop adjustment on cross-cut saws depends on very precise display values. Additional flexibility is offered by the incremental measurement function implemented and by entering offset values.

The AP range is used even in more complex machine environments for easy-to-manage, semi-automated adjustment processes. The “team-based” communication is standardized, and incorrect adjustments are immediately visible in bus-operated mode.
