Siemens 6SE70 inverter alarm F026 F026 fault detection circuit is driven by the sampling, feedback to the CUVC circuit board through the optocoupler, the current detection is too large, automatic detection circuit protection, block pulses.
1, run start to report F026, can not be reset
The fault is manifested in the loss of the drive pulse, self-test alarm of the current Z, and the circuit originals are mostly poor performance of the single drive ceramic chip, and the internal trigger of the IGBT is damaged and the resistance is increased. Peripheral motor short circuit, ground fault will cause fault alarm.
2, start the alarm F026, press the P key can not be reset
This situation occurs more often after the machine is stopped for a few days. When the power is turned on, it is reported as electricity. Due to the bad environment, lack of maintenance, the environment is humid, and the moisture is too high. I parallel resistors cause false alarms in the detection circuit. Usually the processing method is to remove the machine, remove dust and dehumidify. Basically 80% failure is eliminated. If the circuit board is supplied with plus or minus 15 voltages, it will be reported when the drive is not working.
3, CUVC circuit detection chip damage will alarm F026, can be excluded by alternative
