Note
Precautions for 1–phase input to 3-phase drive
•
Warning – 480V units only - When using single phase input, the built-in EMC filter
must be disconnected. See section 2.2, Cable Wiring, Step 6.
•
Please connect single-phase input to R(L1) and T(L3).
•
AC or DC reactor is necessary to reduce DC ripple. For 0.5HP-10HP (0.4~7.5kW), 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, turn off the input phase protection(PR-05).
•
Protection for output current like OCT or IOLT is based on 3-phase ratings. 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.
