Pid Error (Pv–Sp) Deviation Threshold - Hitachi SJ200 Series Instruction Manual

The Error for the PID loop is the magni-
tude (absolute value) of the difference
between the Setpoint (desired value) and
Process Variable (actual value). The PID
output deviation signal [OD] (output
terminal function option code 04)
indicates when the error magnitude has
exceeded a magnitude you define.

signal
Description
Sets the overload signal level
between 0% and 200% (from 0
to two times the rated current
of the inverter)
Sets the frequency arrival
setting threshold for the output
frequency during acceleration,
range is 0.0 to 400.0 Hz
Sets the frequency arrival
setting threshold for the output
frequency during deceleration,
range is 0.0 to 400.0 Hz
Sets the allowable PID loop
error magnitude (absolute
value), SP - PV, range is 0.0 to
100%, resolution is 0.1%
When the PV exceeds this
value, the PID loop turns OFF
the PID Second Stage Output,
range is 0.0 to 100.0%
When the PV goes below this
value, the PID loop turns ON
the PID Second Stage Output,
range is 0.0 to 100.0%
