Delta RMC151 - Manual (Page 873)

9 Register Reference
triggered on a Resolver axis if
the speeds or accelerations
exceed the maximums. See
the Resolver Module
specifications for details.
Position:
Quadrature If the RMC detects an illegal
transition (both A and B
signals transition
simultaneously), or an
overspeed condition (pulse
frequency exceeds maximum
specifications), for a period of
3 loop times, then the Noise
Error bit will be set. During
noise less than 3 loop times,
the Actual Position is
estimated, during which time
the Input Estimated Status bit
will be on.
Velocity,Pressure,
Force:
Analog
If the input rate of change of
the input exceeds the rate
specified by the Noise Error
Rate parameter, then this error
bit will be set.
9 PosOvertravel Positive Overtravel
This bit is set when the Target Position travels beyond the
Positive Travel Limit and is not in the Direct Output state.
The Target Position can exceed the Positive Travel Limit by
up to half a transducer count before this error is triggered.
Note:
This bit turns on only when exceeding the limit or attempting to
go further past the limit. It will turn off if a command is issued
that keeps the axis in the same place or moves it toward the
limit.
10 NegOvertravel Negative Overtravel
This bit is set when the Target Position travels beyond the
Negative Travel Limit and is not in the Direct Output state.
The Target Position can exceed the Negative Travel Limit by
up to half a transducer count before this error is triggered.
Note:
This bit turns on only when exceeding the limit or attempting to
go further past the limit. It will turn off if a command is issued
that keeps the axis in the same place or moves it toward the
limit.
11 CmdErr Command Error
When an invalid command or command with invalid
parameters is issued, this bit is set and an error number is
stored in the Last Error Number status register. Depending
on the Event Log filter settings, this error may also be
logged to the Event Log. See the Error Codes topic for a list
