4.4.3 Status Word according to PROFIdrive Profile (STW)
The Status word is used to notify a master (e.g. a PC) about the status of a
slave.

03 No error Trip
04 OFF 2 ON 2
05 OFF 3 ON 3
06 Start possible Start not possible
07 No warning Warning
08 Speed ≠ reference Speed = reference
09 Local operation Bus control
10 Out of frequency limit Frequency limit ok
11 No operation In operation
12 Drive OK Stopped, autostart
13 Voltage OK Voltage exceeded
14 Torque OK Torque exceeded
15 Timer OK Timer exceeded
Explanation of the Status Bits
Bit 00, Control not ready/ready
When bit 00 = "0", bit 00, 01 or 02 of the Control word is "0" (OFF 1, OFF 2 or OFF 3) - or the frequency converter is switched off (trip).
When bit 00 = "1", the frequency converter control is ready, but there is not necessarily power supply to the unit present (in the event of external 24 V supply of
the control system).
Bit 01, VLT not ready/ready
Same significance as bit 00, however, there is a supply of the power unit. The frequency converter is ready when it receives the necessary start signals.
Bit 02, Coasting/Enable
When bit 02 = "0", bit 00, 01 or 02 of the Control word is "0" (OFF 1, OFF 2 or OFF 3 or coasting) - or the frequency converter is switched off (trip).
When bit 02 = "1", bit 00, 01 or 02 of the Control word is "1"; the frequency converter has not tripped.
Bit 03, No error/Trip
When bit 03 = "0", no error condition of the frequency converter exists.
When bit 03 = "1", the frequency converter has tripped and requires a reset signal before it can start.
Bit 04, ON 2/OFF 2
When bit 01 of the Control word is "0", then bit 04 = "0".
When bit 01 of the Control word is "1", then bit 04 = "1".
Bit 05, ON 3/OFF 3
When bit 02 of the Control word is "0", then bit 05 = "0".
When bit 02 of the Control word is "1", then bit 05 = "1".
Bit 06, Start possible/Start not possible
If PROFIdrive has been selected in par. O-10 Control Word Profile, bit 06 will be "1" after a switch-off acknowledgement, after activation of OFF2 or OFF3, and after
switching on the mains voltage. Start not possible will be reset, with bit 00 of the Control word being set to "0" and bit 01, 02 and 10 being set to "1".
Bit 07, No warning/Warning
Bit 07 = “0” means that there are no warnings.
Bit 07 = “1” means that a warning has occurred.
