        Overview Manuals Signal Inputs Encoder Paths Cam Outputs Front Wiring

        Features:

        • Eleven digital inputs capture reference, measurement, brake, and cam-track enable signals.
        • Incremental, SSI absolute, and two-wire feedback options cover several position-sensor formats.
        • Sixteen short-circuit-protected 24 V outputs switch the configured electronic cam tracks.
        The controller converts encoder position and configured track data into deterministic output changes for machine motion sequences.

        Differential RS422 paths carry high-frequency incremental or SSI information, while the 24 V path handles asymmetrical pulses.

        Encoder supplies, input functions, and cam outputs converge at the 48-pin front connector for cabinet field wiring.

        The Siemens 6ES7452-1AH00-0AE0 FM 452 Electronic Cam Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Machine Reference and Control Signals

        • Input bank: Eleven 24 V digital inputs receive the configured machine and measurement signals.
        • Reference capture: A reference-point switch can establish the positional reference for cam processing.
        • Measurement tasks: Flying actual-value setting and length measurement use configured input events.
        • Output enable: Dedicated functions release the brake and enable cam-track outputs three through ten.

        Supported Position Feedback

        • Differential incremental: A symmetrical 5 V RS422 encoder supplies A, inverted A, B, inverted B, and zero-mark pairs.
        • Single-ended incremental: A 24 V asymmetrical encoder provides A, B, and zero-mark signals.
        • Absolute position: An SSI encoder transfers serial DATA and clock pairs using the differential interface.
        • Sensor option: The module also accepts the documented two-wire sensor connection.

        Position-Dependent Switching

        • Track bank: Sixteen 24 V digital outputs represent configured electronic cam tracks.
        • Load drive: Each active output can supply the documented current within the 0 to 55 °C operating range.
        • Protection: Short-circuit protection limits output damage from a connected field-circuit fault.
        • Timing source: Cam transitions are calculated from the selected encoder position and configured track data.

        Rack-to-Field Connection

        • Connector: One 48-pin front connector carries the digital, encoder, and supply circuits.
        • Encoder power: Separate 5 V and 24 V supplies support the matching feedback-device interface.
        • Cable limits: Maximum encoder lead length depends on voltage, signal type, and selected clock or pulse rate.
        • Rack boundary: The IP20 module remains inside the S7-400 cabinet while field wiring exits through the front connector.
        Description
        Siemens 6ES7452-1AH00-0AE0 is an FM 452 electronic cam controller for generating position-dependent output states in a SIMATIC S7-400 station. Eleven digital inputs collect reference, measurement, brake, and enable signals, while 16 protected digital outputs form the cam tracks.

        Position feedback for 6ES7452-1AH00-0AE0 can come from a symmetrical incremental encoder, a 24 V asymmetrical incremental encoder, an SSI absolute encoder, or a two-wire sensor. The symmetrical and SSI paths use 5 V differential RS422 signaling.

        The SSI interface on 6ES7452-1AH00-0AE0 accepts parameterized 13-bit or 25-bit Gray-code telegrams with clock rates up to 1 MHz. Incremental inputs separately handle A/B track and zero-mark signals at the documented frequency for their electrical format and cable length.

        A 48-pin front connector carries the field wiring for 6ES7452-1AH00-0AE0. Separate 5 V and 24 V encoder supplies, 24 V input/output levels, and short-circuit-protected cam outputs let the module interface the position sensor and machine actuators from one rack position.
