[<CHK>ERR ***-***]
Error detected by the CHK instruction. (The "***"
portion of the error message indicates the
numbers of contact and coil that have been
detected.)
■Collateral information
• Common information: Program error location
• Individual information: Failure No.
■Diagnostic timing
• When instruction executed
Read the individual information of the error
using the programming tool to identify the
numeric value (error number). Check the
program corresponding to the value.
RUN: On
ERR.:Off
USER:On
CPU Status:Continue

[BOOT OK]
Storage of data onto ROM was completed
normally in automatic write to the standard ROM.
(The BOOT LED also flashes.)
■Collateral information
• Common information: -
• Individual information: -
■Diagnostic timing
• At power-on/At reset
Use the DIP switches to set the valid
parameter drive to the standard ROM. Then,
switch power on again, and perform boot
operation from the standard ROM.
RUN: Off
ERR.:Flashing

• Individual information: -
■Diagnostic timing
• When instruction executed
Check and correct the control parameter
setting.
RUN: On
ERR.:On
CPU Status:Continue

9102
[PID ERROR]
A data error has occurred in control parameter or
during PID operation because the proportional
gain (K
P
) setting is out of the range (K
P
<0).
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Check and correct the control parameter
setting.
RUN: On
ERR.:On
CPU Status:Continue

)
setting is out of the range (T
I
<0).
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Check and correct the control parameter
setting.
RUN: On
ERR.:On

) setting is out of the range (K
D
<0 or 201K
D
).
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Check and correct the control parameter
setting.
