PF70 w RIO Logic Status Bit 6 - Alarm Detail

Hi, I have upgraded some drives from 1336Plus to Powerflex70, The drives are on an RIO network. Tidied up PLC code and configs to get the drives running and they are running fine but I am now getting intermittent indication on the Logic Status Word Bit 6 (Alarm) - I'm trying to find out what turns this bit on. I've been through the user manuals for PF70 and RIO but its not highlighting what turns that bit on - does anyone know where to find this out or where to look on the drive.

Thanks.

Are you using a 20-COMM-R RIO Adapter with your Powerflex 70?

You will have to look at P211 or P212 in the drive to see what alarm is actually bring up the alarm bit in the status word.
These are found in Utility/Diagnostics.

Hi, can report we are using 20-COMM-R RIO Adapter with our Powerflex 70s.

So alarm words P211 or P212 contain the current alarm initiators and just reading a bit more looks like P259 works as a mask to enable/disable alarm conditions that will initiate an active drive alarm. so looks like I might have to access the P211 or P212 parameters and latch up that word in the PLC when an alarm comes along or look closer at tuning the alarm bits in P259.

Have a look at Appendix D of this Manual.

Bit 6 is the Deceleration Bit I believe.

The 6th bit is the decel bit. I assume he is looking at the Input word that includes bit 0, so I:xxx/6 is the alarm bit (the 7th bit).
