Product catalog summary

Specifications:
The document outlines the specifications for a motor control system designed for brush sticking direct current (DC) motors operating at 24VDC. It is compatible with DIN rails EN 50022 and EN 50035. The input circuit specifications include an input current of 10mA and an analogue input for rotational speed control using an external potentiometer (10 KOhm) with a range of 0V to 10VDC. The nominal voltage range is 19V to 30VDC.

Output Circuit:
The output circuit features a start-stop ramp timing adjustable from 0.1 to 10 seconds, a maximum rated load current of 8A/5A, and current sensing with short circuit deactivation. It includes dynamic braking and IxR compensation for speed regulation. The power driver is a MOS-FET, and the system operates within an ambient temperature range of -20°C to +60°C.

Further Specifications:
The system includes overload protection and complies with DIN VDE regulations (VDE 0110, 0160). It is designed for snap-fit, modular installation with a screwed or plug-in connection. The case dimensions are 22.5mm x 114.5mm x 99mm.

Control Functions:
The motor control system supports direction reversal, speed control, start-stop ramp functions, and IxR compensation. The control inputs include A1 and A2 for motor start functions, A3 for dynamic braking, and EA and EB for external limit switches. Speed control is managed via a 0-10VDC input or an external potentiometer.

Wiring and Adjustments:
Standard wiring includes connections for start and stop ramps, IxR compensation, and limit switches. The system provides a reference voltage for the potentiometer and allows independent adjustment of start and stop ramp times using front-side trimmers.

Notes Input A1 to A3: The control is conceived for direction of rotation reversal. The clamp 1 (A1) and the clamp 2 (A2) are responsible for the starting functions of the motor. If A1 is powered, the motor starts, if A2 is powered the engine starts into the other direction of rotation. A1 and A2 may be activated not at the same time. When switching off the motor the dynamic brake is activated if the clamp 3 (A3) is not powered ( engine coil is switched to GND (0V). The motor stops immediately. If the clamp 3 (A3) is powered, the dynamic braking is deactivated and the motor is not braked. Input...
