Status Word per FC Protocol
The status word is used to inform the master (e.g., a PC) of the
condition of the slave (drive).

Bit 00, Control Ready:
Bit 00 = 1 The drive is ready for operation.
Bit 00 = 0 The drive has tripped.
Bit 01, Drive Ready:
Bit 01 = 1 The drive is ready for operation, but terminal 27 is a
logic 0 and/or a coasting command has been received via serial
communication.
Bit 02, Standby:
Bit 02 = 1 The drive is able to start the motor when a start
command is given.
Bit 03, No Trip/Trip:
Bit 03 = 0 means that the drive is not in an error state.
Bit 03 = 1 means that the drive has tripped and needs a reset
signal in order for operation to be resumed.
Bit 04, Not in use:
Bit 04 is not used in the status word.
Bit 05, Not in use:
Bit 05 is not used in the status word.

Bit 06, Not in use:
Bit 06 is not used in the status word.
Bit 07, No warning/warning:
Bit 07 = 0 means there is no warning.
Bit 07 = 1 means a warning has occurred.
Bit 08, Speed ¹ Reference/Speed = Reference:
Bit 08 = 0 means that the motor is running, but that the present speed is
different from the preset speed reference. This may be the case when
the speed is being ramped up or down after a start or stop command.
Bit 08 = 1 means that the present motor speed equals the preset speed
reference.
Bit 09, Local Operation/Serial Communication Control:
Bit 09 = 0 means that OFF/STOP has been activated on the control
unit, or that the drive is in Hand mode. It is not possible to control the
drive through serial communication.
Bit 09 = 1 means that it is possible to control the drive through serial
communication.
Bit 10, Out of Frequency Range:
Bit 10 = 0 if the output frequency is outside the range established by the
values in parameter 201, Output Frequency Low Limit, and parameter
202, Output Frequency High Limit.
Bit 10 = 1 means that the output frequency is within the limits of those
parameters.
Bit 11, Not Running/Running:
Bit 11 = 0 means that there is no output from the drive.
Bit 11 = 1 means that the drive has a start signal, or that the output
frequency is greater than 0 Hz.
Bit 12, No Function:
Bit 12 has no function.
Bit 13, Voltage Warning High/Low:
Bit 13 = 0 means that there is no voltage warning.
Bit 13 = 1 means that the DC voltage of the drive intermediate circuit is
too low or too high.
Bit 14, Current Limit:
Bit 14 = 0 means that the output current is less than or equal to the
value in parameter 215, Current Limit.
Bit 14 = 1 means that the output current is higher than the value in
parameter 215, Current Limit, and the drive will trip after the time set in
parameter 412, Trip Delay Overcurrent, has passed if the output
current is not reduced.
Bit 15, Thermal Warning:
Bit 15 = 0 means there is no thermal warning.
Bit 15 = 1 means that the temperature limit has been exceeded either in
the motor, in the drive or from a thermistor connected to an analog
input.
