Check the following before operation:
(1) Check whether the connection is correct,
For 3-phase 230V series, check whether the power supply is connected correctly to the L1/R,
L2/S and L3/T terminals. For single-phase 230V series, check whether the power supply is con-
nected correctly to the L1/L and L2/N terminals. Also check whether the drive grounding terminal
