Programmable Full Scale Offset for Easy Set-Up

You can mount the resolver on the machine without any con-cern for mechanically matching the resolver zero to the machine zero. Once the resolver is coupled to the machine shaft, the only thing you have to do is to bring the machine to a known position, say home position, and set an offset number using the front panel thumbwheel switches until the display reads zero. Now the resolver zero is aligned with the machine zero. This is especially useful during initial start-up in that it reduces the set-up time. The offset can also be used to com-pensate for any wear on the machine.

Variety of Outputs, Built-in PC-Handshake, permit Interface to any PLC

BCD, natural Binary, or Gray Code output formats are avail-able with a choice of TTL, PNP (sourcing) transistor or NPN (sinking) transistor outputs. Optional PLC synchronization circuit provides an error-free method of interfacing BCD posi-tion data from the decoder to any PLC in the market. Upon receipt of a data transfer command from the PLC, the stable data is latched and made available to the PLC

Multiplexing Capability

The TTL type of outputs have multiplexing capability, which allows more than one decoder to be connected to the same control unit for multi-axis applications. For multiplexing PNP or NPN type outputs, consult the factory.

Up to 8192 Counts-per-turn Resolution at 1800 RPM

The DM5 series resolver decoders are available with resolu-tions ranging from 256 to 8192 counts-per-turn to match unlimited control needs. The high-performance ratiometric-tracking converter assures exacting performance at speeds up to 1800 rpm.

Highly Noise-immune Circuitry

The ratiometric tracking converter technique employed for resolver-to-digital (R/D) decoding provides the best protection against electrical noise generated by power line transients, radio frequency interference, and varying ground potentials. A ratiometric converter is practically immune to temperature variations and line frequency changes. Optional optical isolation adds another layer of protection and enhances system integrity.

Extremely Rugged and Reliable Resolver as Position Transducer

The DM5 series of resolver decoders combines the ruggedness of a resolver and reliability of an advanced solid-state control. The rugged heavy-duty NEMA 13 (IP54) resolver can be mounted on a machine shaft in any hostile industrial environ-ment, such as mechanical shock, vibrations, extreme humidity and temperature changes, oil mists, coolants, solvents, etc.; and the resolver-to-digital decoder can be mounted up to 2500 ft (762 m) away in a control panel.
