Specifications

The M1150-M10 is a multi-turn programmable decoder. It
takes the input from a single turn resolver like AVG
Automation's series RL100, which is mounted on the shaft of
the rotating machinery. The M1150-M10 decodes the resolver
signals using highly noise immune ratiometric decoding tech-
nique, scales the digital data based on the programmed Scale
Factor and displays it on the front panel. The position infor-
mation is also made available to the output port in BCD for-
mat for connecting to a remote display or a PLC The position
information is continuously compared to two programmable
preset limits and the outputs are activated when limit condi-
tions are satisfied. All outputs of the M1150-M10 are optically
isolated and the resolver inputs are differential, insuring
extremely reliable operation of the unit even in the harshest of
industrial conditions.
The M1150-M10 will decode the shaft angle to 1/4096th of a
revolution (12-bits) and keep track of multiple revolutions. The
decoder also features tachometer and motion detector, fraction-
al scaling, preprogrammed preset value with an external trigger,
two channels of PLS outputs, full decimal point control, and
PLC synchronization/handshaking for the BCD outputs.
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 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
The M1150-M10 is fully front panel programmable for all
variables, yet secure against any unauthorized program
changes. Opening of an external user-provided keyswitch
inhibits any program changes on the front panel.
