without zero marker has been defined.

328 On reparameterization of the machine data of
the QEC, invalid values have been found. Pos-
sible causes are:
S The characteristic of the conventional QEC
has been incorrectly parameterized.
– The MD 1244* must be less than
MD 1248*.
– The MD 1248* must be less than 100 x
MD 1252*.
– Internal formats have been exceeded with
the characteristic parameterization.
S In the neural QEC, the following errors have
been found.
– The learning rate MD 1368* must not be 0.
– The measuring time MD 1376* must not be
0.
– The neural QEC has been activated
(MD 1812*, bit 0 = 1) although there is no
valid parameterization of the function para-
meters. This can also occur at POWER ON
if the person responsible for installation and
start-up has forgotten to save to a boot file.
