Alarm, fault, and system messages

9.1 Fault codes and interrupts

Interrupts

An interrupt does not shut down the frequency converter. The interrupt number is displayed

and transferred via STARTER and the fieldbus. Interrupt numbers are stored in parameter

r2110 under their code number (e.g., A0503 = 503) and can be read out from here.

Interrupts cannot be acknowledged; they will clear of their own accord, provided that the

cause has been removed.

Fault codes

In the event of a fault, the converter shuts down and the red "SF" LED lights up. The error

code is displayed and transferred via STARTER and the fieldbus.

Fault codes are stored in parameter r0947 under their code number (e.g., F0003 = 3). The

associated error value can be found in parameter r0949. If no error value is assigned to a

fault, the value 0 is entered. The point in time at which the fault occurred can be read out

(r0948), as can the number of the fault code (P0952) that is stored in parameter r0947.

The following sections describe the LED display of fault conditions.

Note

A group fault is only output if it has been enabled via parameter P8452 or the GSD.

Resetting fault codes

To reset the error code, one of the procedures listed below can be used:

● Switch the converter power supply off and on again via the main power supply to the ET

200 station (depending on P1210).

● Set bit 7 in control word 1 (r0054).

● Reset via STARTER.
