5.3 Description of Function Codes 5.3.2 E codes (Extension terminal functions)
Initial diameter set command “D-SET” assignment (Function code data = 169)
Winding diameter calculation hold command “D-HLD” assignment (Function code data = 170)
This signal is used with winding diameter calculation used to calculate the roll winding diameter from the peripheral
speed (line speed) and roll rotation speed when performing constant surface speed control.
( Function codes d158 to d166)
PID control multistage command 1, 2 “PID-SS1”, “PID-SS2” assignment (Function code data = 171, 172)
“PID-SS1” and “PID-SS2” can be used to select 4 different PID commands.
( Function codes J136 to J138)
Acceleration time 2 to 4, Deceleration time 2 to 4 (Refer to F07)
Acceleration/deceleration time 2 to 4 settings are described in detail at the function code F07 section.
Torque limiter 2 (driving), 2 (braking) (Refer to F40)
For the torque limiter 2 (driving) and 2 (braking) settings, refer to the description of F40.
Terminal [Y1] to [Y4](Function selection)
Terminal [Y5A/C], [30A/B/C] (Ry output)
E20 through E24 and E27 assign output signals to general-purpose, programmable output terminals [Y1] to [Y4],
[Y5A/C] and [30A/B/C]. These function codes can also switch the logic system between normal and negative to
define how the inverter interprets the ON or OFF state of each terminal.
The factory default setting is normal logic system “Active ON.” Terminals [Y1] to [Y4] are transistor outputs, and
terminals [Y5A/C] and [30A/B/C] are contact outputs. In normal logic, if an alarm occurs, the relay will be energized
so that [30A] and [30C] will be closed, and [30B] and [30C] opened. In negative logic, the relay will be de-energized
so that [30A] and [30C] will be opened, and [30B] and [30C] closed. This may be useful for the implementation of
failsafe power systems.
• When negative logic is employed, output signal is OFF (active) while the inverter is powered OFF. To
avoid causing system malfunctions by this, interlock these signals to keep them ON using an external
power supply. Furthermore, the validity of these output signals is not guaranteed for approximately 1.5
seconds (for FRN0115G2S-2G/FRN0060G2 □ -4G or below) or 3 seconds (for FRN0146G2S-
2G/FRN0075G2□-4G or above) after power-ON, so introduce such a mechanism that masks them
during the transient period.
• Contact outputs (terminal [Y5A/C], [30A/B/C]) are mechanical contacts. They cannot stand frequent
ON/OFF switching. Where frequent ON/OFF switching is anticipated (for example, by using frequency
arrival signal), use transistor outputs [Y1] to [Y4] instead.
The service life of a relay is approximately 200,000 times if it is switched ON and OFF at one-second
intervals. For signals expected to be turned ON/OFF frequently, use terminals [Y1] to [Y4] for output.
The tables given on the following pages list functions that can be assigned to terminals [Y1] to [Y4], [Y5A/C], and
[30A/B/C]. Each signal has been described at data allocation order. However, the signal is related has been
described together. Refer to the function codes or signals in the “Related function codes/signals (data)” column, if
any.
Explanations of each function are given in normal logic system “Active ON.”
