Note
•
The EPID1–2 output (EPID OUT) is bipolar, and is limited by the EPI-14 (EPID 1 Limit Hi)
and EPI-15 (EPID 1 Limit Lo) settings.
• The following are the variables used in PID operation, and how they are calculated:
- Unit MAX = EPID1 (EPID2) Unit 100% (PID-68 )
- Unit Min = (2xEPID1 (EPID2) Unit0%-EPID1 (EPID2) Unit 100%)
- Unit Default = (EPID1 (EPID2) Unit 100%-EPID1 (EPID2) Unit 0%)/2
EPID Basic Operation Setting Details
Code Description
EPI-01 EPID1 Mode
Sets the EPID1 modes.
Setting Function
0 None EPID1 is not used.
1 Always On EPID1 operates at all times.
2 During Run Operates only when the inverter is running.
3 DI
Dependent
Operates when terminal input (EPID1 Run) is
on.
EPI-02 PID Output
Displays the existing output value for the EPID controller. The unit,
gain, and scale that were set in the EPID group are applied on the
display.
EPI-03 EPID Ref
Value
Displays the existing reference value set for the EPID controller. The
unit, gain, and scale that were set in the EPID group are applied on
the display.
EPI-04 EPID1 Fdb
Value
Displays the existing feedback value set for the EPID controller. The
unit, gain, and scale that were set in the EPID group are applied on
the display.
EPI-05 EPID1 Err
Value
Displays the difference between the existing reference and the
feedback (error value). The unit, gain, and scale that were set in the
PID group are applied on the display.
EPI1-06 EPID1 Ref
Src
Selects the reference input for the EPID control. If the V1 terminal is
set to an EPID1 feedback source (EPID1 F/B Source), V1 cannot be
set as the EPID1 reference source (EPID1 Ref Source). To set V1 as
a reference source, change the feedback source.
