I have a transformer of 600V AC Ouput. Can I Use Drive Whose Input Voltage Rating 3phase 690V AC on the Above mentioned Transformer without any harm or i shall use a transforer whose output shall be 690V AC.?

Hello shivsharma,

The answer to your question depends upon the specific input voltage operating range for the drive.

Drives are normally rated to operate within a specific voltage range.

If drive is rated to operate with input voltage in range of 600 VAC to 690 VAC then the 600 VAC transformer output voltage would be acceptable for drive itself.

However, due to the 600 VAC input you may not be able to achieve the maximum amount of power out of drive to motor to perform application (i.e. due to the lower input voltage the output voltage to motor will be lower and more current will be needed through motor to perform application).

Dear Sir
Our Motor Max. Armature Voltage is 600V DC.I want to know That If i Use 690V Input Supply drive on 600V AC Supply,What will be The Effect. And Our Source Capacity(Transformer) is Sufficient To deliver required Amount of Power To drive.

Dear Sir

DC Motor Details As:

Type: NP400KXSPVA/83 Duty-S1 IP-23

KW 870

V_a 600V DC

I_a1549/1720

V_f330

I_f 13/5.6

RPM 930/1800

Now We Want to Select The Converter for This Motor . We have Source of Supply Voltage 600V AC. So What Shall be the Converter Specification For Trouble free Operation?

Hello,
I would like to suggest you to check 6RA7095-6 or 4 KV62. Please see the attached sheet. Please note the drive selection also depends options to be selected depending upon number of digital I/Os, any other specific logic if needed, technology etc. I would recomend you to contact your near Siemens RSC for more information. Please check the manual of 6RA70 here for more information. Also please check the transformer configuration & drive AC power requirement, power losses & actual application load power demand requirements.
