Product information
Overview
Applications
- Positioning with rapid and slow traverse drives: Supports start/stop positioning, reference cams, reversing cams, and flying actual value setting.
- Drive direction and speed control: Digital outputs provide rapid traverse, creep, run right, and run left functions.
Key Features
- 3-channel positioning: FM 451 positioning module for rapid/slow traverse drives with 3 channels.
- Digital I/O capacity: 12 digital inputs and 12 digital outputs, with 4 inputs and 4 outputs per axis.
- Encoder interfaces: Supports symmetrical and asymmetrical incremental encoders and absolute encoders (SSI).
- Encoder signal performance: Symmetrical incremental encoder input frequency is max. 1 MHz; asymmetrical incremental encoder input frequency is max. 50 kHz, or 25 kHz for 100 m cable length.
- Supply and connection: Rated supply voltage is 24 V DC. The module requires 1x 48-pin front connector.
- Lifecycle and package: Product lifecycle: Announcement of product phase-out. Configuration package is included on CD.
