Hello to everyone, i need help. I have a Siemens motor 1LG4186-4AA10 Z=A23+H57+K20, connected to a S120 Chassis drive 6SL3120-1TE24-5AA3, with a 6SL3055-0AA0-5CA2 connected to the Siemens Encoder 1XP8001-1. The problem is that at the start and at the stop, the motor is vibrating, and the encoder feedback speed is oscillating. I made the autotuning from the drive, at standistill (i tried to make the tuning in movement with the encoder, but i cannot because the drive automatically activate the U/f testing mode, and give error, and this is also another problem that i don't understand), then i made the speed optimization with encoder, without problem. If i start the motor from the master comand of the Scout (4.3.2), no problem, but if i comand the motor from the machine, it starts vibrating for half second, then when increase the speed and reach the cruise speed don't vibrate anymore; but start vibrating when decelerate and is close to stop. I tried to decrease the acceleration and deceleration time, and is little better, but the problem is still there. I check and try to modify all the parameters, also Kp and Ki without success. What can i check to find out and solve the problem? Now i'm in Brasil to start the machine, and i don't know what to do. PS. Other motors ahs the same problem, but is very little, the vibration is very small, but this motor is little more bigger. Here's some graphs from the Scout. Thanks.

Can you give us a reference for the document, so we can ask it at our Siemens representative. Thanks. |
