Hi Rubin, The A017 alarm does exist in CU2 (Even though it is not in the manual - I have had this before due to a transistor fault) 1/. If your drive does not have an option code (-Z K80) then the safe off function can be ignored. An internal hardware fault can also cause a simulated safe off (to protect hardware) 2/. Change P052=3 to upload a complete set of parameters. 3/. I don't either and I work for Siemens 4/. Correct!! 5/. Yes, set P733 = 1 and supply the DC bus with 24V, WITH NO MOTOR connected, you can run the drive and use an oscilloscope to check the drive pulses. But I think the A017 will stop you here, you need to determine what is wrong or repair first.. First thing I would do is to use a diode test across all phases and the DC bus and also between the DC Bus to the motor output terminals. That is 24 separate measurements - see the attached for a clue. Regards, Graeme

Please read the reply of Rubin & try by replacing IVI/IGD from Fibre optic to Flatband type. |
