Bit 00, Control not ready/ready
Bit 00 = ”0” means that the frequency converter
has switched off due to malfunction.
Bit 00 = ”1” means that the frequency converter
control is ready, but that there is not necessarily a
supply to the power unit present (in the case of
external 24 V supply of the control card).
Bit 02, Coasting/Enable
Bit 02 = ”0” means that the bit 03 of the control
word is ”0” (Coasting) or that the frequency con-
