Dear all,
There have been problems with the operation of the AH-629 rotor since a new disc was installed, limiting its maximum speed from 29 000 rpm to 26 000 rpm due to the age of the rotor. The rotor can be used now, but you must select rotor type "Undefined2" from the menu instead of AH-629 until the problem is resolved. We will let you know when the correct rotor type is available again.
Sorry for inconvenience and Merry Christmas!
