6.Wiring diagram

Main circuit wiring attentions
(1)Wiring specifications, please implement wiring in accordance with electrical regulations;
(2)Do not connect alternating current to the output end of the inverter (U, V, W), otherwise the inverter will be
damaged;
(3)Power supply wiring, please try to use the isolation wire and the wire tube, and the isolation wire or the two
ends of the wire tube grounding;
(4)The ground wire of the inverter shall not be grounded together with the welding machine, high-power motor
or high-current load, and shall be grounded separately;
(5)The earthing terminal Please correct
Control loop wiring attentions
(1)Please separate the control signal line from the main circuit line, other power line and power line.
(2)In order to prevent interference and cause wrong action, please use stranded shielding wire or double
shielding wire, the specification is 0.5~2mm squared
(3)Please determine the allowable conditions of each terminal, such as: Power supply, maximum allowable
current, etc.;
(4)Wiring requirements of all terminals, select accessories correctly, such as voltmeter, input power supply, etc.;
(5)Please check the wiring correctly after completion, and power on after confirmation.
7.The load is a single-phase motor
E8.29 Motor type selection:
0: Ordinary three-phase asynchronous motor,
1: Single-phase motor forward rotation (capacitor removed),
2: Single-phase motor reverse rotation (capacitor removed),
3: Single-phase motor (Without removing capacitor).
Single-phase motor description: (E8.29 function parameter is to select the motor type, support single-phase
motor and ordinary three-phase asynchronous motor).
Single-phase motors generally refer to single-phase 220V asynchronous motors. The stator has two-phase
windings and the rotor is a squirrel cage. The distribution of the two-phase windings and different power supply
settings will result in different starting characteristics and operating characteristics.
Ordinary single-phase motors are divided into single-capacitor and double-capacitors. Ordinary single-phase
generally consists of main winding (L1), secondary winding (L2), running capacitor (C1), starting capacitor
(C2), and centrifugal switch (K), as shown in the figure 1:
