9 Register Reference
wire, as indicated by the A Wire
Break and B Wire Break status bits.
This bit is not used by the RMC150.
Resolver The RMC detects an over-speed,
over-acceleration, or voltage error on
the Resolver.
SSI The RMC does not detect any valid
data. The data line is the wrong
polarity at either the beginning of the
serial data stream or the end of the
serial data stream, indicating the line
is not being actively driven by the
transducer.
In general (see the Input Estimated status bit for details and
exceptions, including the RMC150 MDT module), the No
Transducer error bit is not set until the error condition is
present for three consecutive loop times. When a No
Transducer error condition is first detected, the RMC
estimates the position by extrapolating the last two
positions. The Input Estimated Status bit be will be on while
this occurs. After the condition is detected 3 times in a row,
the No Transducer error bit is set. The Input Estimated bit is
always set while the error condition is active, even after the
No Transducer error bit is set following the first 3 loop
times.
Once the No Transducer error bit has been set, it cannot be
cleared until a transducer is detected three loop times in a
row.
7 TransOverflow Transducer Overflow
This bit is set when the RMC detects an overflow on the
input from the transducer. The following list indicates when
this occurs for various transducer types.
Analog
Voltage
±10V Range (RMC70): The voltage
is greater than +10.1V or less than -
10.1V.
±5V Range (RMC150): The voltage
is greater than +5.04V or less than -
5.04V.
±10V Range (RMC150): The
voltage is greater than +10.08V or
less than -10.08V.
Analog
Current
RMC70: The current exceeds 21mA.
RMC150: The current exceeds
20.1mA.
MDT RMC70: The RMC does not detect a
stop pulse (for Start/Stop) or falling
edge on the Return pulse (for PWM)
by the end of the control loop.
RMC150: The RMC has not detected
a stop pulse (for Start/Stop) or falling
