Siemens G120c debugging synchronous motor, alarm current is too low
|
|
Siemens G120c debugged the synchronous motor through Botu v15. According to the debugging and guiding steps, there is no mistake. It has repeatedly confirmed that there is no problem with the motor parameters. However, once it is running, it will report 7929 warning, and the motor can not be detected. The reason is that the current is too small to be detected online, about 0.1A, and the nameplate of the motor is 6.3A. What's the matter, please? Do you need to deal with it?
It must be loaded, the load is not small, 140 times the speed reducer with a transmission roller.
1. Has the motor static identification been done after fast debugging? It must be done in the vector control mode.
2. Check the feeder circuit and whether the motor is running.
3. Check if the given speed is too small.
4. Appropriate adjustment of initial load detection current limit P2179, output load detection delay.
Motor Static Recognition Reference "G120 Static Recognition"
Has the motor been loaded yet? What's the rating?
No load, low rating current is normal, too small to see if it is a hardware problem.
Check wiring and motor winding.
Let's do motor identification and optimize the motor.
Is it a third-party motor? Maybe the static identification of the motor has not been done, maybe refer to the manual to do static and dynamic identification before looking at it.
It should be that the load of the motor is low.
