Fixed output setting
The output range is limited by the setting of "Output limiter (MODE0 and MODE3)".
Output preset
In P control operation, the control calculation output will be 50% when the deviation is zero (PV = SV).
This output value can be set arbitrarily. This function can be used as a kind of manual reset.
Note that changing the output preset value during operation may cause rapid variation in output.
PV abnormal output
Sets the output value at the occurrence of measured value (PV) over-range, burnout, and internal data
error.
For the specification with 2output, the output 2 will be 0% under all conditions.
Preset manual
This function is used to set the output value at the READY status (constant value operation) beforehand.
The output value can also be set by "External input (MODEd)".

Control algorithm
The control algorithm may not be suitable for some control targets. The instrument has two types of
control algorithm.
Position PID control
The position PID control uses the PID calculation method that calculates the operation amount from the
deviation (difference between SV and PV). This method is effective for a control target with relatively slow
response.
Velocity PID control
The velocity PID control uses the PID calculation method that calculates the variation in operation amount
from the deviation (difference between SV and PV). This method is effective for a control target with
relatively fast response.
