Code Description
EPI-07 EPID1 Ref Set
Set the EPI control reference type (EPI-06) to ‘0 (Keypad)’ to enter the
reference value.
EPI-09 EPID1 P-Gain
Sets the output ratio for differences (errors) between the reference and
feedback. If the P-Gain x 2 is set to 50%, then 50% of the error is output.
The setting range for P-Gain is 0.0-1,000%.
EPI-08 EDPID1 Fdb Src
Selects the feedback input for the EPID control. When the V1 terminal is
set to an EPID feedback source (PID F/B Source), V1 cannot be set as the
PID reference source (PID Ref Source). To set V1 as a reference source,
change the feedback source.

1 V1 -10-10 V input voltage terminal
3 V2 I2 analog input terminal [When analog
voltage/current input terminal selection switch
(SW4) at the terminal block is set to I (current),
input 0-20 mA current. If it is set to V (voltage),
input 0–10 V voltage]

EPI-10 EPID1 I- Time
Sets the time to output accumulated errors. When the error is 100%, the
time taken for 100% output is set. When the integral time (EPID I-Time) is
set to 1 second, 100% output occurs after 1 second of the error
remaining at 100%. Differences in a normal state can be reduced by
EPID I Time.
All the accumulated errors can be deleted by setting the multi-function
terminal block to ‘42 (EPID1 ITerm Clr)’ or ‘48 (EPID2 ITerm Clr)’.
EPI-11
EPI1 D-Time
Sets the output volume for the rate of change in errors. If the differential
time (EPID1 D-Time) is set to 1 ms and the rate of change in errors per
sec is 100%, output occurs at 1% per 10 ms.
EPI-12 EPID1 FF-Gain
Sets the ratio that adds the target to the EPID output. Adjusting this
value leads to a faster response.
EPI-13EPID1 Out LPF
Used when the output of the EPID controller changes too fast or the
entire system is unstable, due to severe oscillation. In general, a lower
value (default value=0) is used to speed up response time, but in some
cases a higher value increases stability. The higher the value, the more
