Bit 10, Data not valid/Data valid:
Tell the adjustable frequency drive whether to use or ignore the control word. Bit 10 = ’0’: The control word is ignored. Bit 10 = ’1’: The control word is
used. This function is relevant because the message always contains the control word, regardless of the message type. Thus, you can turn off the control
word if you do not want to use it when updating or reading parameters.
Bit 11, Relay 01:
Bit 11 = "0": Relay not activated. Bit 11 = "1": Relay 01 activated provided that
Control word bit 11
is chosen in par. 5-40
Function Relay
.
Bit 12, Relay 04:
Bit 12 = "0": Relay 04 is not activated. Bit 12 = "1": Relay 04 is activated provided that
Control word bit 12
is chosen in par. 5-40
Function Relay
.
