This is slightly OT but I hope some of our members who use Siemens AC variable frequency drives can help me out. I am trying to diagnose some communication problems between Siemens drives using a DeviceNet CBD interface board and an Emerson DeltaV controller.
The drives are Siemens SIMOVERT VC drives, specifically part number 6SE7221-3ES00-3AC0-Z and have the OPS1 keypad /LCD interface on the front of the cabinet. I do not have access to the SIMOVIS drives software.
I'm trying to understand the format of the parameter numbers and specifically the Fault Log.
The parameters of the drive seem to be hierarchical; a parameter number will appear as "r947.001" and will have several sub-parameters; r947.002, r947.003, r947.004, and so on. I've seen up to 64 of these sub-parameters.
In particular I'm trying to figure out the Fault Log. To navigate to it, I press:
[P] *Select Menu
[P] *Param Menu
[P] *Diagnostics
[P] *Fault/Warning
and then I use the up-arrow to get to Parameter P782 "Trip Time", for example, where there are multiple sub-entries.
p782.001 Trip Time T1-d 0
p782.002 Trip Time T1-h 0
p782.003 Trip Time T1-s 0
p782.004 Trip Time T2-d 13
p782.005 Trip Time T2-h 20
p782.006 Trip Time T2-s 3584
p782.007 Trip Time T3-d 13
p782.008 Trip Time T3-h 20
p782.009 Trip Time T3-s 3499
p782.010 Trip Time T4-d 13
p782.011 Trip Time T4-h 17
p782.012 Trip Time T4-s 615
So the first question is about the Trip Time. Is it the time since the trip until the present time ? Or is it the time since the drive was powered up until a Trip ? Or something else ?
The drive was presently faulted with a Safe Off trip Fault 017.
If any PLCTalk users who are familiar with these drives can give me some OPS1 navigation advice or point me towards a document that describes these parameters in detail (all I have is VC_BA_Einbau_AC_d_e.pdf) that would be very much appreciated.
