It's better not to exceed the third levels for the big drive control small motor. The main reason is that the self-learning of motor parameters is not accurate, and VF will be better. But our VF is vectorized, which is also related to the motor parameters. So please use VF control, try to get rid of the influence of vector control, please start from the following directions:
(1) The rated parameters of the motor are set correctly
(2) Set the slip compensation factor P04.09=0
(3) Adjust the low speed and high-speed oscillation suppression factor properly, generally to set it bigger (fine-tune), to see the effect
(4) Carrier frequency can be increased, such as 2K ~ 4K

There are below possible reasons, please check one by one.
1. There is no short circuit jumper between + 24 V and PW on the terminals;
2. The + 24 V power supply on the terminal is abnormal, please test;
3. If only one digital terminal is invalid, that means the circuit corresponding to that terminal is damaged, other terminals can be used for test;
4. The terminal polarity is set incorrectly;
5. The function parameters of the corresponding terminals of VFD are set improperly, please check the parameters.

AH is the capacity of battary. The relationship between battary capacity and power quantity is as below: 1kWH=1000W*H=1000V*AH(V: voltage; A: Current; H: hour)

1.Keep cooling of all component,such as panels,distribution box,inverter.A water spray cooling device can be installed around the components.

2.Set up a sunshade for inverter.When installing inverters and distribution boxes, it is better to install them in places with sunshade and rain shelter.

32.

The maximum operating temperature of IGBT is 85 ℃.The maximum operating temperature of the phase-shifting transformer is 110℃

The current maximum power unit rating is 722A

The possible causes of this failure are:
1. The keypad is damaged or the keypad cable is not connected properly, so the keypad and keypad cable can be replaced and powered on again;
2. If the control board fails, the control board can be replaced and powered on again;
3. The connection line of the drive board is not in good contact, so it can be re connected and powered on;
4. The power supply of the drive board fails, and the power supply of the drive board can be replaced.
