08 1 = Speed deviation within the tolerance
range
Se
tpoint / actual value deviation within the toler‐
ance range.
09 1 = Control requested The automation system has been requested to
take o
ver control of the converter.
10 1 = Comparison speed reached or exceeded Speed is greater than or equal to the correspond‐
ing maximum speed.
