Siemens 6FM1715-3AA10 Cam Control Unit

This Siemens cam control unit generates precise switching signals based on shaft position. The Siemens 6FM1715-3AA10 replaces mechanical cams with electronic accuracy. Its robust design ensures reliable operation in demanding production environments. This unit suits packaging, printing, and textile machinery applications. The Siemens 6FM1715-3AA10 provides flexible cam adjustment without mechanical modifications.

Physical Dimensions and Mounting Specifications

The cam control unit measures 232 mm in height and 25 mm in width. Its overall depth reaches 160 mm including the front connector. This unit weighs approximately 0.52 kilograms for stable rack installation. The housing supports standard 35 mm DIN rail mounting in S5 racks. The Siemens 6FM1715-3AA10 features a 20-pin front connector for all signal wiring. This connector accepts conductor cross-sections from 0.5 mm² to 2.5 mm².

Cam Configuration and Output Specifications

This unit provides 8 programmable cam outputs for switching applications. Each output delivers 24 V DC at 0.5 A for direct actuator control. The cam resolution reaches 1 degree of shaft rotation for precise switching. Switch-on and switch-off points adjust independently for each cam. The Siemens 6FM1715-3AA10 accepts encoder signals for position detection. The unit supports incremental encoders with 5 V differential outputs. A reference input allows synchronization with machine cycles.

Electrical Characteristics and Data Storage

The unit draws a typical current of 120 mA from the 24 V DC supply. It includes a 470 µF capacitor for energy storage during brief interruptions. This capacitor ensures stable operation during momentary power dips. The Siemens 6FM1715-3AA10 stores cam settings in non-volatile memory. A lithium battery maintains cam parameters for up to 5 years. LED indicators display the status of each cam output channel.
