9105
[PID ERROR]
A data error has occurred in control parameter or
during PID operation because the derivative time
(T
D
) setting is out of the range (T
D
<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
LCPU
QnUDV
9106
[PID ERROR]
The sampling time (T
S
) setting is shorter than the
operation cycle.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Set the sampling time (T
S
) so that it will be
longer than the operation cycle.
RUN: On
ERR.:On
CPU Status:Continue

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