What it means
F34836 reports that a DRIVE-CLiQ communications error has occurred from the Control Unit to the Voltage Sensing Module (VSM): data were not able to be sent. The manuals describe the fault for the VSM identically across the families that list it, so one description covers them all. Alongside the error itself the drive stores a component number and a fault cause in the message value; the fault cause listed for this code is 65 (= 41 hex), which means that Telegram type does not match send list
.
Why it appears
- A DRIVE-CLiQ communications error has occurred from the Control Unit to the Voltage Sensing Module (VSM) — data were not able to be sent.
- The fault cause recorded with this fault is 65 (= 41 hex): the telegram type does not match the send list.
What to check
- Carry out a POWER ON. This is the remedy the manual gives for F34836, and it lists no further steps.
Reading the message value
- The message value carries two items: the component number (%1) and the fault cause (%2).
- The manual codes this information in the message value (read in r0949/r2124) as 0000yyxx hex: yy is the component number, xx is the error cause.
- Fault cause 65 (= 41 hex) stands for: telegram type does not match send list.
Parameters the manual names
- r0949 — fault value: read the coded message value for F34836 here; it holds the component number and the fault cause in the 0000yyxx hex pattern.
- r2124 — alarm value: the register the manual names alongside r0949, in which the same coded information for this message appears.
Acknowledging and restarting
This fault is acknowledged immediately. The manual's remedy is to carry out a POWER ON; once that has been done, the fault is acknowledged and the drive can be restarted.
What differs between the drive families
Straight from the manuals' own fields — F34836 is not described identically everywhere.
