r2120 CO: Sum of fault and alarm buffer changes / Sum buffer changed
Access level: 4
Unit: -
Description: Displays the sum of all of the fault and alarm buffer changes in the drive unit.
Dependency: Refer to: r0944, r2121
r2121 CO: Counter, alarm buffer changes / Alrm buff changed
Access level: 3
Unit: -
Description: This counter is incremented every time the alarm buffer changes.
Dependency: Refer to: r2110, r2122, r2123, r2124, r2125
r2122[0...63] Alarm code / Alarm code
Access level: 2
Unit: -
Description: Displays the number of alarms that have occurred.
Dependency: Refer to: r2110, r2123, r2124, r2125, r2134, r2145, r2146
Note: The buffer parameters are cyclically updated in the background (refer to status signal in r2139).
Alarm buffer structure (general principle):
r2122[0], r2124[0], r2123[0], r2125[0] --> alarm 1 (the oldest)
. . .
r2122[7], r2124[7], r2123[7], r2125[7] --> Alarm 8 (the latest)
When the alarm buffer is full, the alarms that have gone are entered into the alarm history:
r2122[8], r2124[8], r2123[8], r2125[8] --> Alarm 1 (the latest)
. . .
r2122[63], r2124[63], r2123[63], r2125[63] --> alarm 56 (the oldest)
r2123[0...63] Alarm time received in milliseconds / t_alarm recv ms
Access level: 3
Unit: [ms]
Description: Displays the system runtime in milliseconds when the alarm occurred.
Dependency: Refer to: r2110, r2122, r2124, r2125, r2134, r2145, r2146, p8400
Notice: The time comprises r2145 (days) and r2123 (milliseconds).
Note: The buffer parameters are cyclically updated in the background (refer to status signal in r2139).
The structure of the alarm buffer and the assignment of the indices is shown in r2122.
r2124[0...63] Alarm value / Alarm value
Access level: 3
Unit: -
Description: Displays additional information about the active alarm (as integer number).
Dependency: Refer to: r2110, r2122, r2123, r2125, r2134, r2145, r2146
Note: The buffer parameters are cyclically updated in the background (refer to status signal in r2139).
The structure of the alarm buffer and the assignment of the indices is shown in r2122.
