Note
Precautions for 1–phase input to 3-phase drive
• Please connect single-phase input to R(L1) and T(L3).
•
AC or DC reactor is necessary to reduce DC ripple. Please select built-in reactor type
for 30-75kW. For 0.4-22kW, external AC or DC reactor should be installed.
• Same peripheral devices (including a fuse and reactor) as 3-phase can be used for 1-
phase as well.
•
If phase open trip occurs, please turn off the input phase open protection(PR-05).
• Protection for output current like OCT or IOLT is based on 3-phase input ratings which
is larger than single-phase input. User should set the parameters that are relative to
motor information(bA-11~16), overload trip(Pr-17~22) and E-thermal functions(Pr-
40~43)
•
Performance of sensorless control could be unstable depending on DC ripple.
• The minimum input voltage must be larger than 228Vac for 240Vac supply and 456Vac for
480Vac supply to ensure motor voltage production of 207Vac and 415Vac, respectively.
• To minimize the effect of voltage deprivation, please choose 208Vac motor for 240Vac
supply and 400Vac motor for 480Vac supply.
