XGB Analog edition manual
15 - 54
It describes error codes and warning codes of the XGB built-in PID function. The error codes and
warning codes that may occur during use of the XGB built-in PID function are summarized as table.
If any error or warning occurs, remove potential causes of the error by referring to the tables.
15.6.1. Error codes
It occurs when max. MV is set lower than min. MV. Make
sure to set max. MV larger than min. MV.
It occurs when max. PV is set lower min. Pv. Make sure to
set max. PV larger than min. PV.
It occurs when the period of auto tuning or PID operation
loop is set under 100(10ms). Make sure to set output
period more than 100.
It occurs when SV is larger than PV at the start time of
auto-tuning if auto-tuning is forward or when SV is larger
than PV at the start time of auto-tuning if auto-tuning is
reverse.
It occurs when the junction designated as PWM output
junction is beyond between P20 ~ P3F.
It occurs when proportional constant is set lower than 0.
It occurs when integral time is set lower than 0.
It occurs when differential time is set lower than 0.
It occurs when control mode is not P, PI, PD or PID.
It occurs when operation direction is changed during auto-
tuning. Never attempt to change operation direction during
auto-tuning.
It occurs when period of operation is smaller than 100
(10ms) at Auto-tuning or PID operation.
Make sure to set period of operation larger than 100.
In mixed operation, It occurs when the direction parameter
of forward operation set to reverse operation or the
direction parameter of reverse operation set to forward
operation. Make sure set to appropriate direction each
loop.
In mixed operation, it occurs when the Set value of each
loop is not concurrent. Make sure set to Set value
concurrently.
