11-2 Error Messages
An error message will appear if incoming data has any of the errors listed in table. Since the error is shown in the display for
informational purposes, the data transfer continues and you are allowed to perform the next operation.
To get the error message to go away, press the
ENTER
key.
Note that even though the error message is no longer displayed after you press thee
ENTER
key, the CM-500/400/300 will retain in
memory the fact that the error occurred. To clear the error internally, you can give the default instruction, IN; or the error code
output instruction, OE. (The error can be cleared by turning the power off.)
The error messages and their meanings are as follows:
Error massage Meaning
Er1:Command
Not Recognized
Appears if an instruction that the CM-500/400/300 cannot interpret is sent. This error is
generated if an instruction from the “mode2” set is sent when the unit has been set to
recognize “mode1,” or viceversa. Change the setting for the recognized instruction set, using
the control panel, and this error should no longer occur.
Appears if the number of parameters differs from the permissible number.
Er2:Wrong Number
of Parameters
Appears if the value specified for a parameter is out of the permissible range.
Er3:Out of
Parameter range
Appears if an unusable character is specified.
Er5:Unknown
Character Set
Appears if an output instruction is sent from the computer during execution of a previous
output instruction. More precisely, there is a certain amount of delay between the moment an
output instruction is given and the instant actual output begins. This error message appears if
the new output request arrives during this delay time. (The delay time can be set using the
[ESC].M instruction.)
Er10:Output
Request Overlap
Appears if a device control instruction that the CM-500/400/300 cannot interpret is sent.
Er11:Command
Not Recognized
Appears if an invalid parameter has been specified for a device control instruction.
Er12:Wrong
Parameter
Appears if the value for a device control instruction parameter exceeds the permissible limit.
Er13:Out of
Parameter range
Appears if the number of parameters for a device control instruction is more than that
permissible.
Er14:Termination
Error
Er15:Framing/
Parity Error
Appears if the I/O buffer has overflowed.(There is a problem with the connecting cable, or
the settings for Handshaking. Make sure you are using a cable appropriate for the computer
being used. Also, check that the setting for Handshaking is correct.)
Er16:Buffer
Overflow
Appears if the I/O buffer has overflowed.(There is a problem with the connecting cable, or
the settings for Handshaking. Make sure you are using a cable appropriate for the computer
being used. Also, check that the setting for Handshaking is correct.)
Er18:
Indeterminate
Appears if a framing error, parity error, or overrun error occurs at the time of data
reception.(There is a problem with one of these settings: Baud Rate, Parity, Stop Bits, or Data
Bits. The protocol settings for the CM-500/400/300 must be made correctly in order to match
the settings your computer is set to use.)
