 Power supply specification for DC feeding (Standard models)
Rated input DC voltage
Permissible fluctuation
NOTE
• The voltage between P and N will temporarily increase to 1057 V or higher during the regenerative driving, so take caution
on the selection of the DC power supply.
• When an AC power supply is connected to the R/L1, S/L2, and T/L3 terminals during the DC feeding with Pr.30 = "10" (DC
feeding), an option fault (E.OPT) will occur.
• When the input voltage is insufficient during inverter operation with Pr.30 = "10, 20" (DC deeding), the inverter output will
be shut off. (The undervoltage protection function (E.UVT) is not activated.)
• When set to Pr.30 = "10, 20" (DC feeding) and operated by DC feeding, detection of Instantaneous power failure (E.IPF)
is not performed.
• When DC power is switched on, a larger inrush current flows than in AC power. The number of power-on times should be
minimized.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) or Pr.190 to Pr.196
(Output terminal function selection) may affect the other functions. Set parameters after confirming the function of each
terminal.
