Debugging and Application
Before the products manufactured by our company are delivered out from factory, all have inspected
comprehensively. However the process of loading, discharging and transportation, all may bring harmful
effect to the products. For that reason, after you get the products, you should test them all-round in
accordance with the following specific steps firstly:
6.1 Debugging Operating
6.1.1
Debugging Wiring
Power Supply through the air switch connects the power input terminals L1 and L2, the ground wire connects
to PE and put the output terminals U,V and W to the winding motor and U1,V1 and W1 to the Extra-feeding
motor.
6.1.2
Inspection before Power On
◆
Whether or not the converter is installed in the environmental requirements
◆
Whether or not the wiring of converter is correct and the sectional area of the power circuit is satisfactory.
◆
Whether or not the rating input voltage and the rating input power can match to the AC power source.
When finished the wiring, it is to be sure that inside the converter and on the field must put in order.
◆
◆
The converter must be operated by the specially trained technicians.
6.1.3
Debugging with Power on
1. After convinced that the connection is right and every preparation is ready, then can put on the power to
the converter. After the power supply is put on, the keyboard controller displays “-YT-”, about after 5
seconds, the converter enters its normal standby mode and displays the length of last time of the machine
operating.
2. Entering into the parameter’s setting mode, its concrete steps please refer to the “Operation Illustration of
the Keyboard.”
3. After finishing the parameter’s setting
，
pushing the operating key can make the converter run and can
employ the electromagnetic or electrodynamics
multi-meter to measure and test the output voltage of the
converter. It must be sure that the three phase voltage of the terminals U, V, W and U1, V1, W1 ought to
balance, namely each voltage between every two phase must be equal by each other. When the operating
frequency attains 50Hz, the output voltage by measuring should be equal to 220V and the three voltages of
the three phases ought to be equal.
