General information

Indicating fault and alarm messages (faults and alarms)
A message comprises a letter followed by the relevant number.
The letter characterizes the message type and has the following meaning:
 A means "Alarm"
 F means "Fault"
 N means "No Report" or "Internal Report"
Brackets including the letters A, F, or N indicate that the message type can be
changed, e.g. A01016 (F) means that the warning A01016 can be parameterized
as a fault. The letter in brackets shows which message type can be adjusted via
parameters p2118 and p2119.
Example:
p2118[5] = 1016 (warnung A01016 (F) "Firmware changed")
p2119[5] = 1 (p2119 = 1 equal fault (F))
In this way the warnung "Firmware changed" will become a fault.
Faults are stored in parameter r0945/r0947 under their code number (e.g. F01003
= 1003). The associated fault value is found in parameter r0949. The value 0 is
entered if a fault has no fault value. It is furthermore possible to read out the point
in time that a fault occurred (r0948) and the number of faults (p0952).
Alarms are stored in parameter r2110/r2122 under their code number (e.g.
A01503 = 1503) and can be read out from there. The associated alarm value is
found in parameter r2124 and the point in time that a alarm occurred in r2123.
The time stamp for the faults and warnings is read out from parameters p8400
and p8401. This is valid for the parameters r0948, r2109, r2123, r2125, r2130,
r2136, r2145, r2146.
