Configuring the CX1000/CX2000
Proportional band (P)
Specify between 0.1 and 999.9%.
Integral Time(I)
Specify between 0 and 6000s.
Derivative Time(D)
Specify between 0 and 6000s.
Output Lower Limit
Set the output lower limit between –5.0 and 105.0% such that upper limit > lower limit.
Output Upper Limit
Set the output upper limit between –5.0 and 105.0% such that upper limit > lower limit.
Shutdown
Turn the shutdown function ON or OFF. Available when the Setup tab’s Internal
Loop > Output Process > Control output setting is set to Current output, and analog
retransmission is set to 4-20 mA.
Manual Reset
Set the manual reset between –5.0 and 105.0% of the output value.
Relay Hysteresis (Value)
Set the relay hysteresis in EUS (0.0 to 100.0%).
Relay Hysteresis (Point)
Select the Hysteresis operating point when using ON/OFF control from [Mid], [Lower
Limit], or [Upper Limit].
Preset Out
Select a fixed control output value from -5.0 to 105.0% to be used when operation is
stopped.
Reverse/Direct
Select reverse/direct switching from [Direct] or [Reverse].
Note
[Relay Hysteresis (Value)] and [Relay Hysteresis (Point)] appear in PID Parameters when
[Control Output] is set to [On/Off-control] under [Setup] > [Internal Loop] > [Output process]. In
that case, [PID], [Output Limit], [Shutdown], and [Manual Reset] are not shown.
