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
Coefficient for Constant Feeding Rate Time
E50 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
Coefficient for speed indication
(E50)
Constant feeding rate time (min) =
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.
E52
Keypad (Menu display mode)
E52 provides a choice of three menu display modes for the keypad as listed below.
Data for E52 Menu display mode Menus to be displayed
0 Function code data editing mode Menu #1
1 Function code data check mode Menu #2
2 Full-menu mode Menus #1 through #6 *
* Menus #1 through #7 when a remote keypad is connected.
Selecting the full-menu mode (E52 = 2) allows you to cycle through the menus with
the or key and select the desired menu item with the key. Once the entire
menu has been cycled through, the display returns to the first menu item.
