Heidelberg CPTronic Press cannot inch/run.

Hi Forumers,
We have in our fleet a CPTronic MOz that can neither inch nor Run because of an error Initest SVT 0302,Dyn Test SVT 7FFE which is shown on the CPTronic Screen after Powering the machine On;
All applied remedies has failed.These include testing of the SVT,REKs,SAK,ESK,SRK, 120volts dc supply to field via K48 cpontaactor,Caable,ble linkingSRK to SVt,Complete SLT,RER backplane motherboard on a siimilaar press where they all tested okay but when returned to this press we have these errors.
We will therefore require the assistance of the Gurus or someone who has seen and resolved this problem before to please give us suggestions on how to resolve this notty problem.
Thanks in advance of help.

SVT 0302 in init test 1 shows power converter board SRK has failed.

 

Thanks Junker,
We have used the power converter board SRK,the SVT board and other boards mentioned in my earlier post above on a similar machine without these errors hence i concluded that they are okay.

Dear forumers,pls forgive my omission of the additional errors SBM 0000 and SLTCON 0000- on Initest in addition to the SVT 0302 error on Initest and Dynamic Test SVt 7FFE.
Thanks.

Do you have errors on KVT?

 

Hi Nimesh,
Machines with SVT ,SLT dirveboards are not equipped with a KVT board for brushless drives.

Dear Forumers,
This Fault is now cleared and machine is now okay.Problem was due to frequency deviation which was low from the private power supply generating set .
Immense thanks to the contributors for their timely responses.
