Learning Advanced Features
• 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
EPID1 operates at all times.
Operates only when the inverter is running.
Operates when terminal input (EPID1 Run) is
on.
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.
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.
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.
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.
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.
