What it means
Alarm A01302 reports an error in the component trace. The drive raises it when trace data is uploaded (p7792 = 1) or when the factory setting of the component trace signal and trigger (p7790, p7791) is changed although the component involved does not have the "component trace" property (r0193.1 = 0). The alarm value in r2124, read as a decimal number, identifies which case applies.
Why it appears
- An error occurred while the component trace data was being uploaded (p7792 = 1).
- The factory setting of the component trace signal and trigger (p7790, p7791) was changed for a component that does not have the "component trace" property (r0193.1 = 0).
What to check
- Read the alarm value in r2124 and interpret it as a decimal number to see which case the drive is reporting.
- If the alarm value is 1, upgrade the firmware of the DRIVE-CLiQ component involved.
- The manuals name a remedy only for alarm value 1; for the values 101 to 105 no further measures are described.
Reading the message value
The drive stores the alarm value in r2124; interpret it as a decimal number:
- 1: The DRIVE-CLiQ component does not support the component trace (r0193.1 = 0).
- 101: Data from trace 1 cannot be read.
- 102: Data from trace 2 cannot be read.
- 103: Data from trace 3 cannot be read.
- 104: Data from trace 4 cannot be read.
- 105: Data from trace 5 cannot be read.
Parameters the manual names
- r2124 — holds the alarm value of this alarm; read it as a decimal number to identify the case.
- p7792 — set to 1 to upload the component trace data, one of the operations during which A01302 appears.
- p7790 — component trace signal; its factory setting is changed in the missing-property case.
- p7791 — component trace trigger; changed together with p7790 in the same case.
- r0193 — bit 1 (r0193.1) shows whether the "component trace" property is present; 0 means it is missing.
What differs between the drive families
Straight from the manuals' own fields — A01302 is not described identically everywhere.

Questions technicians ask
What does alarm A01302 mean on a SINAMICS drive?
It reports an error in the component trace. The alarm appears when trace data is uploaded (p7792 = 1) or when the factory setting of p7790 and p7791 is changed although the component lacks the "component trace" property (r0193.1 = 0).
How do I fix A01302?
Read the alarm value in r2124 as a decimal number. If it is 1, upgrade the firmware of the DRIVE-CLiQ component involved — this is the remedy the manuals give.
What do alarm values 101 to 105 of A01302 mean?
101 means data from trace 1 cannot be read; 102 to 105 mean the same for traces 2 to 5. The manuals give a remedy only for alarm value 1.
Which parameters belong to alarm A01302?
p7792 (upload component trace data), p7790 and p7791 (component trace signal and trigger), r0193.1 (trace property present or missing) and r2124 (alarm value).
