Applications
- Servo and stepper motor positioning: Provides 3-channel positioning for servo and stepper motors.
Key Features
- 3-channel positioning: FM 453 function module for positioning with servo and stepper motors; 6 configurable digital inputs and 4 configurable digital outputs are provided for each channel/axis.
- Encoder interfaces: Supports symmetrical incremental encoders and absolute encoders with SSI; encoder signals use a 5 V difference signal (phys. RS 422).
- 24 V supply: Rated auxiliary and load voltage is 24 V DC. The permissible range is 20.4 V to 28.8 V, with dynamic limits of 18.5 V to 30.2 V.
- Signal and timing data: Incremental encoder input frequency is up to 1 MHz for 10 m cable length and 0.5 MHz for 35 m cable length. Stepper drive pulse frequency is 200 kHz.
- Front connection: Requires 1x 48-pin front connector. Module dimensions are 50 mm width, 290 mm height, and 210 mm depth.
- Protection and isolation: Digital outputs have short-circuit protection. Digital inputs and digital outputs are electrically separated by optocouplers.
