Dear NADIM Please Check the following : 1) Re-check the parameters set by you P081= 1 - Field Weakening Activated: For this settingField Weakening Optimisation must be executed P083=4 - Actual Speed Feedback - Freely Wired ? P100=1 - Rated Armature Current = 1 Amp P102=0.01 - Rated Field Current = 10ma !!!!! - Tthe Parameters set by you are for DC Motor with Field Wekening. For Bulb Load , you should set as follows : P081 = 0 : No Field Weakening P082 = 0 : Disable Field P083 = 3 :Actual Speed Feedback = EMF Actual Value 2) Do you have the Safety Shutdown contact wired across XS : 105 - 106 ? 3) What is the Operating Status r000 indicated on the drive. This will indicate whether the Drive is waiting for any pre-conditions for Run. a) Pl Download the 6RA70 Manual and read Ch 6 & 7 for wiring and Startuo b) Pldownload and use Drivemonitor software from the link and use the same for commissioning. Drivemonitor also includes an "Assisted Commissioning" wizard to easily startup and run a drive. Hope this helps Cheers Navnag |

Hello NADIM For this, you should simply use a adjustable DC power supply. That will be much simpler and easier than using a 6RA70 for the task. We have a saying ... why use a sword, where only a needle is needed to do the job Cheers Navnag |

Hello Mr Nadim, Regret for late reply. From your posts what I understood you is you want 40Volt 55 watt DC power supply, simply for powering electromagnet application. Considering the application, it is not appropriate or economical as well as wise decision to go for 6RA70 DC drive. (Though customer insist. Some time we should suggest customer the appropriate & economical solutions, as customer may not be technical competent in electrical field. If customer doesn’t agree then it is left at him/her)In your case you should go for simple step down transformer with full rectifier bridge of appropriate current capacity. (Transformer VA rating should be250 VA & rectifier capacity should be 15 A, to be on safer side considering inrush current) One more suggestion to you is, MR. KSNis very sound technical expert in DC convertors as well as other Siemen’s products & Mr Navnagis quite senior forum member. So you must respect their views & try to understand them. It’s good for your technical knowledge improvement. Hope you will take this advice in right spirit. |

Hello. For those who are still interested there is a link to the newFAQ, related to the question of this thread. For NADIM:
Please, don't click on above posted link, this is pdf manual, which does not contain full parameter list for your application.
