(9) Reset selection at main circuit power ON (Pr. 30)
At initial status, inverter resets at main circuit power ON when using separated power source for main circuit (R/L1,
S/L2, T/L3) and control circuit (R1/L11, S1/L21). With this parameter, you can select to perform inverter reset or not at
main circuit power ON.
• Pr. 30 = "0, 1, 20, 21" ......................With inverter reset (Settings of "20 and 21" are for power failure)
• Pr. 30 = "100, 101, 120, 121" ..........Without inverter reset
* Settings of Pr. 30 = "2 (for FR-HC, MT-HC and FR-CV), 10 and 11(for DC feeding mode 1)" are for DC power supply,
and therefore reset selection is not available.
REMARKS
The MRS signal can also be used instead of the X10 signal. (Refer to page 117.)
Refer to pages 31 to 38 for connection of the brake unit, high power factor converter (FR-HC, MT-HC) and power regeneration
common converter (FR-CV).
When AC power is connected to terminal R/L1, S/L2, T/L3 during DC feeding with "2, 10 or 11" (DC feeding) set in Pr. 30, an
option alarm (E.OPT) occurs.
When DC feeding operation is performed with "2, 10, 11, 20, 21, 120 or 121" (DC feeding) set in Pr. 30, undervoltage protection
(E.UVT) and instantaneous power failure (E.IPF) are not detected.
CAUTION
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Please
set parameters after confirming the function of each terminal.
WARNING
The value set in Pr. 70 must not exceed the setting of the brake resistor used.
Otherwise, the resistor can overheat.
