1. If the fault code presented on the Schneider inverter is AnF, it means that the load of the inverter has slipped, that is, the speed of the encoder does not match the initial value. First of all, we need to check whether the parameters of the motor are stable and the size of the load, and then replace a brake resistor and mechanical coupling.
2. If the fault code presented on the inverter is brF, it means that the mechanical braking of the inverter has failed, that is to say, the contact and logic are different, we need to check whether the mechanical state of the braking circuit and the brake is normal.
3. If the fault code presented on the inverter is bUF, it means that the braking unit of the inverter has been short-circuited or the inverter is not connected to the braking unit at all. Let's see if there is a problem with the braking unit and resistors.
4. If the fault code presented on the inverter is ECF, then it means that there is a problem with the encoder connection, or the connector is broken, we only need to check whether there is a problem with the mechanical coupling of the encoder, and if there is a problem, replace a mechanical coupling.
5. If the fault code presented on the inverter is EnF, then it means that the encoder presents a problem, first of all, we need to check whether the number of pulses is correct and whether the encoder type is correct, if it is accurate, we will check whether the encoder is operating normally.
6. If the fault code presented on the inverter is FCF1, then it means that the output contactor may not be opened.
7. If the fault code presented on the inverter is OCF, it means that the inverter presents an overcurrent problem, which may be because the parameters of the inverter are set incorrectly or the load is too large.

The method of controlling the speed of the motor by the inverter - Schneider
1. Why can the rotation speed of the motor be changed freely?
Motor rotation speed unit: r/min number of rotations per minute, can also be expressed as rpm.
Example: 2-pole motor 50Hz 3000 [r/min]
4-pole motor 50Hz 1500 [r/min]
Conclusion:...

How Schneider UPS properly configures the backup battery
In order to ensure that the APCUPS power supply can continue to supply high-quality power to the computer even in the event of a power outage, it is important to equip the battery backup battery. When the load is not allowed to be powered, the UPS battery backup time in the communication room should be greater than the time from the mains power interruption to the rehabilitation or to the generator set is positive.

Schneider Thermal Relay Model Meaning
The function of the thermal relay is mainly used to carry out overload maintenance on the asynchronous motor, and his operating principle is that after the overload current passes through the thermal element, the bimetal sheet is heated and twisted to advance the action organization to drive the contact action, so as to disconnect the motor control circuit to realize the motor power-off thermal relay ...

Schneider thermal relay selection method
1. In principle, the ampere-second characteristics of the Schneider thermal relay should be as close as possible to or even coincide with the overload characteristics of the motor, or under the overload characteristics of the motor, and at the same time, the Schneider thermal relay should not be affected (not acting) at the moment of short-term overload and start of the motor.
