Specifications

receipt of a data transfer command from the PLC, the stable
data is latched and made available to the PLC. The PC-
Handshake, being an edge-triggered device, allows stable data
to be read every scan by a 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.
High-Resolution, Up to 17-bit Total
The DM960 is a multi-turn system with a resolution of 10-
bits-per-turn over 64 or 128 turns. This means 17-bit resolu-
tion over total travel with 128-turn system or 16-bit resolution
with 64-turn system. The high-speed ratiometric-tracking con-
verter utilized in the DM960 decoder series permits operation
at speeds up to 1800 rpm and still assures 1 part in 1000 per
turn resolution.
Highly Noise Immune Circuitry
Ratiometric tracking converter technique employed for
resolver-to-digital 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 isola-
tion adds another layer of protection and enhances system
integrity.
Extremely Rugged and Reliable Resolver as
Position Transducer
The DM960 resolver decoder combines the ruggedness of
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 environment, such
as mechanical shock, vibrations, extreme humidity and tem-
perature 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.
