Drives

[Elsys]

We have two VSDs (PF 700S) that are configured for sugar centrifugals we are using here at our factory. Both applications run with and active regeneration units,

(1336 R) which activate when slowing the centrifugal down after its high speed cycle.

Both machines have been running well for approximately 8 months with no problems.

Today for no reason one of the machines VSD stopped on a fault F# 129 and does not enable even when the input 16 (drive enable) is made.

The power supply to the out puts of the drive is also present. Non of the wiring has been changed.

If I look at the diagnostics menu on the HIM (PF 700S) then on the “view fault queue” we have the following faults,

 FLT# 1 129

                                                                                                                                     FLT# 2   11 Motor overload

                                                                                                                                     FLT# 3   11 Motor overload

                                                                                                                                     FLT# 4   39 Power EE CRC fail

                                                                                                                                     FLT# 5 130 Fault queue cleared.

The status LED on the HIM is flashing green. Can you please assist with this problem and advise what to do. Urgent please

what is F129 it does not show in the fault code

Hi, the Fault F129 *is* in the manual, page 4-11 ....

It is just an indication that the Faults have been cleared... just check if F11 is an old indication or it maybe the cause of your stop...

Anyway the Green status led just indicate the drive is ready to work ..., so right now no faults are present...

Hope this helps,
