 Low current detection “IDL”, Low current detection 2 “IDL2”
This signal turns ON when the output current drops below the level specified by E37 (Low current detection, Level)
for the period specified by E38 (Timer). When the output current exceeds the “Low current detection level plus +5 %
of the inverter rated current,” it goes OFF (minimum output signal width: 100 ms). “IDL” is output even when the
inverter is stopped. “IDL2” is valid only during inverter output (“RUN” ON).
Fig. 5.3-22
The inverter rated current changes based on the F80: Operation mode (HHD/HND switching) setting value.
Refer to “Chapter 12 “SPECIFICATIONS” for details.
E36
Frequency detection 2 (Refer to E31)
Refer to the description of E31.
E37, E38
Current detection 2/Low current detection (level and timer) (Refer to E34)
For details about Current detection 2/Low current detection (level) (timer), refer to the description of E34.
E39
Display coefficient for transport time
Related function code: E50 (Display coefficient for speed monitor)
E39 specifies the constant-rate feeding time, load shaft speed, coefficient for line speed setting, and coefficient for
output status monitor indication.

The “Frequency” in the above formula is set frequency when each indication is the setting value (constant-rate
feeding time setting, load shaft speed setting, and line speed setting), whereas it is output frequency before slip
compensation when the indication is output status monitor.
When the constant-rate feeding time is 999.9 (min) or greater, or the denominator on the above formula is 0, “999.9”
is displayed.
E50 is the speed display coefficient applied when motor 1 is selected. A60, b60, r60, respectively, are applied when
motor 2, 3, or 4 is selected.
