FC 300 Profibus
Status Word according to FC 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 telegram 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 command 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.
