System 200V - Function modules

Structure and Function

Function modules are intelligent modules, the technological tasks such as position determination, counting and positioning, and other complex functions in the automation run autonomously.

FM 250 - SSI-Modules

The SSI module enables the connection of absolute coded reading recorders with an SSI interface. The module converts the serial information of the reading recorder into parallel information and makes this available to the controller. There is a possibility to transmit the data in Gray or binary code. In addition to the SSI signals clock, data and encoder supply there are two additional outputs that can be set or reset when crossing.

FM 250 - Counter

The counter counts the pulses of the connected sensor and processes these stimuli according to the selected module. The module has 2 or 4 channels at a width of 32 bit or 16 bit respectively, with 20 counter modes and two DC 24 V outputs, which are controlled depending on the mode.

FM 253/254 – Positioning Modules

Positioning modules can be used for point-to-point positioning and for complex travel profiles with the highest standards of accuracy, dynamism and speed. The FM 253 is a Positioning module for controlling a stepper motor. Stepper motors are used when maximum torque at low speeds is required and the target position is to be achieved and maintained without overshooting. The FM 254 is a positioning module for controlling a servo drive. The module operates independently and is controlled by a corresponding application program from the CPU. The module has 3 inputs for connecting limit switches and can control 2 outputs.
