4.4.2. Status Word under Instances 20/70 and 21/71
The status word in Instances 70 and 71 is de-
fined in the overview to the right:
Explanation of the Bits:
Bit 0, Fault:
Bit 0 = "0" means that there is no fault in the frequency converter.
Bit 0 = "1" means that there is a fault in the frequency converter.
Bit 1, Warning:
Bit 0 = "0" means that there is no unusual situation.
Bit 0 = "1" means that an abnormal condition has arisen.
Bit 2, Running 1:
Bit 2 = "0" means that the drive is not in one of these states or that Run 1 is not set.
Bit 2 = "1" means that the drive state attribute is enabled or stopping, or that Fault-Stop and bit
0 (Run 1) of the control word are set at the same time.
Bit 3, Running 2:
Bit 3 = "0" means that the drive is in neither of these states or that Run 2 is not set.
Bit 3 = "1" means that the drive state attribute is enabled or stopping, or that fault-stop and bit
0 (Run 2) of the control word are set at the same time.
Bit 4, Ready:
Bit 4 = "0" means that the state attribute is in another state.
Bit 4 = "1" means that the state attribute is ready, enabled or stopping.
Bit 5, Control from net:
Bit 5 = "0" means that the drive is controlled from the standard inputs.
Bit 5 = "1" means that DeviceNet has control (start, stop, reverse) of the drive.

Note that the bits 00 and 02 in Instance 70 are identical with bits 00 and 02 in the
more extensive Instance 71.
