Description
QPP MDI BLOCK LOOKAHEAD ERROR
Only one of two necessary blocks was programmed in MDI using QuickPath Plus commands
that require two blocks for proper execution.
QPP NOT ALLOWED DURING POLAR MODE
With polar coordinate programming active, you cannot use QPP.
R
R WORD FORMAT FINER THAN
The word format programmed is requesting a finer resolution than the axis word format for the
corresponding axis allows. These word formats are set in AMP.
RAPID SPEED TOO HIGH FOR AMPED CONFIG
AMP configuration error. The axis resolutions and feedback device resolutions will not permit
the rapid and maximum feedrates assigned in AMP.
RADIUS TOO SMALL
An arc (or helix) was programmed (G02 or G03) that defines a radius that is too small to connect
the start-point of the arc to the end-point. The value of R is too small.
RAPID TOO HIGH FOR AMPED CONFIG
AMP configuration error. The axis and feedback device resolutions will not permit the rapid
feedrates assigned in AMP.
RAPID TRAVERSE ERROR :
An attempt was made to jog an axis using rapid traverse when it is not permitted. Typically, to
use the TRVRS function while jogging, the control must be in manual mode; continuous jog
must be selected; and, if the axis being jogged has an overtravel value, that axis must first have
been homed.
READ ERROR
An attempt to read a program from a tape or disk drive has failed.
RECIP AXIS IN WRONG PLANE
The reciprocation axis specified in a G81 or a G81.1 programming block is not in the currently
selected plane.
RECIP AXIS NOT PROGRAMMED
No reciprocation axis was specified in a G81 or a G81.1 programming block.
RECIPROCATION NOT STOPPED
An attempt was made to deactivate the current part program while reciprocation is still active.
You must deactivate reciprocation before deactivating the current part program.
REMOTE I/O COMMON RAM FAULT ON RESET
The RIO module tests the common RAM after reset and detects an error. The Interboard
Communications Fault LED is turned ON.
REMOTE I/O CTC CHIP TEST FAULT
The RIO module tests the CTC chip after reset and detects a fault. The Processor Fault LED is
turned ON.
REMOTE I/O DENIED COMMON ACCESS ON RESET
The RIO module was denied access to CRAM for more than 1 second after reset. The
Interboard Communications Fault LED is turned ON.
REMOTE I/O EPROM INTEGRITY FAULT
The checksum test over the RIO program area in the EPROM chip found a fault. The Processor
Fault LED is turned ON.
REMOTE I/O INCORRECT USER BT DATA AMOUNT
The RIO module attempted to read a block of data from one of the user output block transfer
data buffers in common RAM and found the word count of the data to be outside of the range of
1 to 64. The Interboard Communications Fault LED is turned ON.
REMOTE I/O INITIALIZATION ERROR
Remote I/O hardware or network has failed to initialize. Cycle power to try to restart or check
remote I/O hardware (9/290 only).
REMOTE I/O INTERNAL RAM FAULT
The RIO module tests its internal RAM chip after reset and during operation. A fault has been
detected. The Processor Fault LED is turned ON.
REMOTE I/O INTERRUPT HARDWARE FAULT
The RIO module detects that its CPU was not interrupted by any expected external interrupts.
This condition indicates a problem in recognizing interrupts. The Processor Fault LED is turned
ON.
REMOTE I/O INVALID RACK ADDRESS SET UP
The RIO module’s rack address is illegal. This fault is the result of the user setting the rack
address, via the dip switches, to an invalid rack size and/or starting module group number.
REMOTE I/O INVALID USER BT DATA CHECKSUM
The 16-bit 2’s complement checksum calculated by the RIO module using data from a user
output block transfer data buffer does not match the checksum placed in the buffer by the user
device. The Interboard Communications Fault LED is turned ON.
REMOTE I/O INVALID USER DATA CHECKSUM
The 16-bit 2’s complement checksum calculated by the RIO module using data from the user
output data table in common RAM does not match the checksum placed by the user in the user
output data table in common RAM. The Interboard Communications Fault LED is turned ON.
