4.5.2 Status Word according to GE Drive Profile (STW)

The status word is used to inform the master (e.g. a PC) of the operation mode
of the slave (frequency converter).

Please refer to Application examples for an example of a status word mes-
sage using PPO type 3.

Explanation of the Status Bits

Bit 00, Control not ready/ready
Bit 00 = "0" means that the frequency converter has tripped.
Bit 00 = "1" means that the frequency converter controls are ready, but that
the power component is not necessarily receiving any power supply (in case
of external 24 V supply to controls).

Bit 01, Drive ready
Bit 01 = "1". The frequency converter is ready for operation, but there is an
active coasting command via the digital inputs or via serial communication.

Bit 02, Coasting stop
Bit 02 = "0". The frequency converter has released the motor.
Bit 02 = "1". The frequency converter can start the motor when a start com-
mand is given.

Bit 03, No error/trip
Bit 03 = "0" means that the frequency converter is not in fault mode.
Bit 03 = "1" means that the frequency converter is tripped, and that a reset signal is required to re-establish operation.

Bit 04, No error/error (no trip)
Bit 04 = "0" means that the frequency converter is not in fault mode.
Bit 04 = 1 means that there is a frequency converter error but no trip.

Bit 05, Not used
Bit 05 is not used in the status word.

Bit 06, No error / triplock
Bit 06 = "0" means that the frequency converter is not in fault mode.
Bit 06 = 1 means that the frequency converter is tripped, and locked.

Bit 07, No warning/warning
Bit 07 = "0" means that there are no warnings.
Bit 07 = "1" means that a warning has occurred.

Bit 08, Speed reference/speed = reference
Bit 08 = "0" means that the motor is running, but that the present speed is different from the preset speed reference. It might, for example, be the case while the
speed is being ramped up/down during start/stop.
Bit 08 = "1" means that the present motor present speed matches the preset speed reference.

Bit 09, Local operation/bus control
Bit 09 = "0" means that [STOP/RESET] is activated on the control unit, or that Local control in par. F-02 Operation Method is selected. It is not possible to control
the frequency converter via serial communication.
Bit 09 = "1" means that it is possible to control the frequency converter via the network/ serial communication.
