PARAMETERS
Power supply specification for DC feeding (Standard models and IP55
compatible models)
NOTE
• The voltage between P and N will temporarily increase to 415 V (830 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 = "2, 10, 11"
(DC feeding), an option fault (E.OPT) will occur.
• When set to Pr.30 = "2, 10, 11, 20, 21" (DC feeding) and operated by DC feeding, detection of undervoltage (E.UVT) and
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.

WARNING
The value set in Pr. 70 must not exceed the setting of the brake resistor used.
It may cause overheating.
