What it means
A35200 (TM: Calibration data) reports that an error was detected in the calibration data of a Terminal Module (TM). Which component and analog channel is affected, and what kind of error it is, is coded in the alarm value in r2124. Depending on how the drive is configured, the same condition can also be issued as a fault (F) or without any reaction (N).
Why it appears
- An error was detected in the calibration data of the Terminal Module.
- According to the fault type coded in the alarm value, either no calibration data is available for a channel (b = 0) or the offset is too high, more than 100 mV (b = 1) — on an analog input (AI) or an analog output (AO).
What to check
- Read the alarm value in r2124 and interpret it as a decimal number (ddcbaa): it identifies the component, whether an analog input (AI, c = 0) or an analog output (AO, c = 1) is affected, the fault type (b) and the number (aa).
carry out a POWER ON (switch-off/switch-on) for all components
.- If the message reappears afterwards, replace the component if necessary.
Reading the message value
- The drive stores the alarm value in r2124; interpret it as a decimal number with the structure ddcbaa.
- dd = component number
- c = AI/AO: c = 0 — analog input (AI); c = 1 — analog output (AO)
- b = fault type: b = 0 — no calibration data available; b = 1 — offset too high (> 100 mV)
- aa = number
Parameters the manual names
- r2124 (Alarm value) — read this value as a decimal number to find out which Terminal Module component and which AI or AO channel is affected and which of the two fault types is present.
Acknowledging and restarting
As an alarm, A35200 requires no acknowledgement. The remedy is to switch all components off and on again (POWER ON); if the message then persists, the component has to be replaced if necessary. If the drive raises the same condition as a fault (F), it is acknowledged IMMEDIATELY (POWER ON); with no reaction (N) there is nothing to acknowledge.
The same on every family
Every manual that describes A35200 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Hardware/software error (1) | Terminal Module (TM) | SINAMICS S120, S150 List Manual · p. 3212 |
| G130, G150 | NONE | NONE | Hardware/software error (1) | Terminal Module (TM) | SINAMICS G130, G150 List Manual · p. 1880 |

Questions technicians ask
What does alarm A35200 (TM: Calibration data) mean on a SINAMICS drive?
The drive has detected an error in the calibration data of a Terminal Module (TM). The alarm value in r2124 shows which component and analog channel is affected and whether calibration data is missing or the offset is too high (> 100 mV).
How do I fix A35200?
Carry out a POWER ON, i.e. switch all components off and on again. If the message reappears, the component must be replaced if necessary.
Does A35200 have to be acknowledged?
No, as an alarm it requires no acknowledgement. Only if the drive is configured to issue the condition as a fault (F) is the acknowledgement IMMEDIATELY (POWER ON).
How do I decode the A35200 value in r2124?
Interpret r2124 as a decimal number ddcbaa: dd is the component number, c distinguishes the analog input (AI, c = 0) from the analog output (AO, c = 1), b is the fault type (0 = no calibration data available, 1 = offset too high) and aa is the number.
