Control
Explanation of the bits
Bit 0, Run fwd
Bit 0 = 0: The frequency converter has a stop command.
Bit 0 = 1: The frequency converter starts the motor in
clockwise direction.
Bit 1, Run rev
Bit 0 = 0: The frequency converter has a stop command.
Bit 0 = 1: The frequency converter runs the motor in
4 4
counterclockwise direction.
Bit 2, Fault reset
Bit 2 = 0: There is no trip reset.
Bit 2 = 1: A trip is reset.
Bit 3, No function
Bit 3 has no function.
Bit 4, No function
Bit 4 has no function.
Bit 5, Net control
Bit 5 = 0: The frequency converter is controlled from the
standard inputs.
Bit 5 = 1: EIP controls the frequency converter.
NOTICE
Changes affect parameter 8-50 Coasting Select to
parameter 8-56 Preset Reference Select.
Bit 6, Net reference
Bit 6 = 0: Reference is from the standard inputs.
Bit 6 = 1: Reference is from EIP.
NOTICE
Changes affect parameter 3-15 Reference Resource 1 to
parameter 3-17 Reference Resource 3. For the speed
reference, see chapter 4.5.2 Bus Speed Reference Value
under Instances 20/70 and 21/71.

Table 4.9 Status Word Bits in Instances 70 and 71
Explanation of the bits
Bit 0, Fault
Bit 0 = 0: There is no fault in the frequency converter.
Bit 0 = 1: There is a fault in the frequency converter.
Bit 1, Warning
Bit 0 = 0: There is no unusual situation.
Bit 0 = 1: An abnormal condition has occurred.
Bit 2, Running 1
Bit 2 = 0: The frequency converter is not in 1 of these
states, or Run 1 is not set.
Bit 2 = 1: The frequency converter state attribute is
enabled or stopping, or fault-stop and bit 0 (Run 1) of the
control word are set at the same time.
Bit 3, Running 2
Bit 3 = 0: The frequency converter is in neither of these
states, or Run 2 is not set.
Bit 3 = 1: The frequency converter state attribute is
enabled or stopping, or fault-stop and bit 0 (Run 2) of the
control word are set at the same time.
Bit 4, Ready
Bit 4 = 0: The state attribute is in another state.
Bit 4 = 1: The state attribute is ready, enabled, or stopping.
Bit 5, Control from net
Bit 5 = 0: The frequency converter is controlled from the
standard inputs.
Bit 5 = 1: EIP has control (start, stop, reverse) of the
frequency converter.
Bit 6, Ref from net
Bit 6 = 0: The reference comes from inputs to the
frequency converter.
Bit 6 = 1: The reference comes from EIP.
Bit 7, At reference
Bit 7 = 0: The motor runs, but the present speed is
different from the preset speed reference, that is, the
speed is ramped up/down during start/stop.
Bit 7 = 1: The frequency converter and reference speeds
are equal.
