Low current detected --
IDL
This signal turns ON when the output current drops below the low current detection level
(E34) and remains at the low level for the timer period (E35). When the output current
exceeds the "Low current detection level plus 5% of the inverter rated current," it goes OFF.
(The minimum ON-duration is 100 ms.)
E39
E50
Coefficient for Constant Feeding Rate Time
Coefficient for Speed Indication
E39 and E50 specify coefficients for determining the constant feeding rate time, load shaft
speed, and line speed, as well as for displaying the output status monitored.
Calculation expression
Constant feeding rate time (min) =
Coefficient for speed indication (E50)
Frequency × Coefficient for constant feeding rate time (E39)
Load shaft speed = Coefficient for speed indication (E50) × Frequency (Hz)
Line speed = Coefficient for speed indication (E50) × Frequency (Hz)
Where, the "frequency" refers to the "reference frequency" to be applied for settings (constant
feeding rate time, load shaft speed, or line speed), or to the "output frequency before slip
compensation" to be applied for monitor.
If the constant feeding rate time is 999.9 min. or more or the denominator of the right-hand
side is zero (0), "999.9" appears.
E51
Display Coefficient for Input Watt-hour Data
Use this coefficient (multiplication factor) for displaying the input watt-hour data (
5_10
) in a
part of maintenance information on the keypad.
Input watt-hour data = Display coefficient (E51 data)
Input watt-hour (kWh)
Setting E51 data to 0.000 clears the input watt-hour and its data to "0." After
clearing, be sure to restore E51 data to the previous value; otherwise, input
watt-hour data will not be accumulated.
