The M1150-M10

Prescalable, Presettable; Yet Absolute

A wide-range of easy to set programmable scale factors (0.3-4095.999) eliminates the need of mechanical gear trains and prescales the display to readout directly in engineering units. Any preset number can be jammed into the position "counter" by a front panel switch or an external signal, thus "offsetting" or "rezeroing" the machine in no time. The M1150-M10 is unique in that it can be prescaled and preset and still is absolute over the entire-range in single-turn operation. In multi-turn applications it keeps track of the true position, if the resolver movement does not exceed half-a-revolution after power loss.

Simple Front-Panel Programming

TheM1150-M10 is fully front-panel programmable for all variables, and yet secure against any unauthorized program changes. Opening of an external user-provided keyswitch inhibits any program changes on the front panel.

No Batteries, Nonvolatile Memory

Nonvolatile EEROM memory retains information indefinitely after power loss or machine shutdown, eliminating batteries and related hazards.

Replacing Electromechanical Selsyn Systems

In new installations, the M1150-M10 together with AVG Automation's brushless resolver series RL100 is a 100% solid-state replacement for electromechanical Selsyn systems.

PC-Handshake for PLC Synchronization

On an external command, such as data transfer command from a PLC, the digital shaft-angle position can be "frozen" at the input of the PLC in order to ensure that the data is not sampled during transition from one angle to the next, and that the PLC always reads a valid data. The unit may be set-up in transparent mode using keyboard commands.

Reliable Under Extreme Environments

The M1150-M10 combines the ruggedness of a brushless resolver and reliability of a solid-state control. The resolver can be mounted on a machine shaft in any hostile environments such as mechanical shock, vibrations, extreme humidity and temperature changes, oil mists, coolants, solvents, etc., and the pro-grammable unit M1150-M10 can be mounted up to 2500 ft (762 m) away in control panel. The splash-proof, oil-tight front plate of the M1150-M10 unit guarantees perfect operation even in unfavorable conditions like steel mills. The ratiometric converter assures high-tracking speed (700 RPM) and high-noise immunity.

Built-in Tachometer and Motion Detector

The shaft RPM is displayed continuously on the front panel. The motion detector output is energized when the shaft is rotating within programmed motion limits.
