What it means
A13021 is raised when the configuration of the converter results in an output frequency greater than 550 Hz. Operation above that frequency is a licensed function: the "High Output Frequency" license is required, and this alarm indicates that it is missing. While the license is missing, the drive limits the output frequency to 550 Hz. Note that the "Trial License" function is not effective for the "High Output Frequency" license, so a trial license cannot be used as a substitute.
Why it appears
- The configuration of the converter results in an output frequency greater than 550 Hz.
- Operation above 550 Hz is a licensed function, and the required "High Output Frequency" license is missing.
What to check
- Enter the license key for the "High Output Frequency" license in p9920.
- Activate the entered license key with p9921.
- If necessary, operate the motor below the output frequency of 550 Hz instead.
Parameters the manual names
- p9920 — enter the license key for the "High Output Frequency" license here.
- p9921 — activate the license key entered in p9920; entering and activating the key is the remedy for this alarm.
Acknowledging and restarting
No acknowledgement is required for this alarm. While the license is missing, the drive limits the output frequency to 550 Hz and continues to run. The alarm is resolved by entering the license key in p9920 and activating it in p9921 or, alternatively, by operating the motor below the output frequency of 550 Hz.

Questions technicians ask
What does alarm A13021 mean on a SINAMICS drive?
It means the converter configuration results in an output frequency greater than 550 Hz, and the "High Output Frequency" license required for operation above 550 Hz is missing. In this case the drive limits the output frequency to 550 Hz.
How do I clear alarm A13021?
Enter the license key for "High Output Frequency" in p9920 and activate it with p9921. Alternatively, operate the motor below the output frequency of 550 Hz.
Can a Trial License be used for output frequencies above 550 Hz?
No. The manual states that the "Trial License" function is not effective for the "High Output Frequency" license, so it cannot substitute for it.
Which parameters are involved in alarm A13021?
p9920 is used to enter the license key and p9921 to activate it.
