FM 451 — 3-channel positioning module for rapid/slow (fast/creep-speed) traverse drives, 24V DC supply, typ. current 550mA, includes configuration package on CD, supports reference cams, reversing cams, flying actual value setting. [VERIFIED via Siemens official datasheet]

Technical Specifications

Module Type Function Module (Positioning)
Channels 3 (4 digital inputs per axis, 12 total)
Compatible Drive Speed Range Rapid/slow traverse (fast and creep-speed) drives
Power Supply 24V DC
Typical Current Consumption 550 mA
Supported Functions Reference cams, reversing cams, flying actual value setting, start/stop, SSI absolute encoder support
Included Configuration package on CD

Typical Applications

Used for positioning control specifically suited to two-speed (rapid/slow) drive systems, an earlier-generation alternative to the FM 453 for motion control applications on S7-400 systems where the drive operates at distinct fast and slow traverse speeds rather than continuously variable speed.
