Application
The TM PosInput 1 counter and position detection module detects fast signals with high frequencies and returns the counter reading or position and the current speed to the controller. The counter control ensures a precise counter result and rapid response in the system via integrated digital input and output signals. Comprehensive parameterization options provide optimum adaptation to the task at hand and reduce control load.
The module supports position detection with SSI absolute encoders with a telegram length of 10 to 40 bits. Max. 31 of these bits are position information, the other bits are sensor status information. Single-turn and multiturn encoders are supported at a clock frequency up to 2 MHz.
Design
Suitable BaseUnits
The standard BaseUnits (A0) of ET 200SP are available for connection. The individual signals of the PosInput module are connected to the appropriate terminals.
A light BaseUnit opens a new load group. The supply voltage must be fed in via this BaseUnit. The first BaseUnit next to the interface module must always be a light BaseUnit.
A dark BaseUnit forwards the supply voltage of the adjacent light BaseUnit on the left via self-assembling voltage buses. A new infeed is therefore only required on the next light BaseUnit to the right.
All variants that correspond to BaseUnit type A0 can be used as BaseUnits.
Labeling
Light gray and yellow labeling strips in two different materials are available for labeling the modules:
- Foil, roll with 500 strips, for thermal transfer roll printer
- Paper (280 g/m2), DIN A4 sheets with 100 strips each, for laser printer
System-integrated shield connection
For the space-saving and EMC-optimized connection of cable shields, a shield connection is available that is quick and easy to mount. This consists of one shield connection element that can be plugged onto the BaseUnit and one shield terminal for each module. The low-impedance connection to functional ground (DIN rail) is carried out by the user and requires no additional wiring.
