6ES7453-3AH00-0AE0 Siemens SIMATIC S7-400 FM453 3 channel 24VDC

1.Overview of the 6ES7453-3AH00-0AE0 Siemens

The Siemens 6ES7453-3AH00-0AE0 is the FM 453 positioning function module from the SIMATIC S7-400 family. It plugs and plays within the same chassis, enabling independent or coordinated positioning control of three axes without consuming additional CPU resources. Powered by a 24 V DC power supply and consuming only 8 W typical, the module can provide encoder power up to 300 mA at 5 V for servo or stepper motors. It also supports 5 V and 24 V encoder interfaces with cable lengths up to 35 m and 100 m, respectively, meeting the long-distance signal requirements of large equipment.

Each channel features six configurable digital inputs and four short-circuit-protected digital outputs, with input latency as low as 15 µs, enabling rapid capture of high-speed signals such as origin, limit switches, and probes. The outputs can directly drive motor enable, brakes, or external relays, achieving a compact design with zero external components. Built-in electronic cams, absolute/incremental encoders, and an SSI multi-turn interface support complex processes such as linear axes, rotary tables, flying shears, and trailing shears. Positioning accuracy ≤ ±0.01 mm and repeatability ≤ ±0.001 mm ensure single-calibration and long-term stability for high-speed filling, labeling, and handling production lines.

The module comes with a STEP 7 configuration package and graphical debugging tool, allowing wizard-based configuration of mechanical parameters, speed profiles, and acceleration/deceleration times in just ten minutes. It supports S7 standard function blocks (FC/FB) and synchronizes with the CPU cycle, with a refresh rate of as fast as 1 ms. With its compact IP20 form factor (290×210×50 mm) and wide operating temperature range of -25°C to +60°C, the 6ES7453-3AH00-0AE0 is widely used in high-end OEM equipment such as packaging machinery, lithium battery winding, semiconductor packaging, and robotic handling. It is an ideal choice for multi-axis, high-speed, and precise positioning.
