9. RS-485 Installation and Set-up
Bit 04, No error/error (no trip):
Bit 04 = '0': The frequency converter is not in fault mode. Bit 04 = "1": The frequency converter shows an error but does not trip.
Bit 05, Not used:
Bit 05 is not used in the status word.
Bit 06, No error / triplock:
Bit 06 = '0': The frequency converter is not in fault mode. Bit 06 = "1": The frequency converter is tripped and locked.
Bit 07, No warning/warning:
Bit 07 = '0': There are no warnings. Bit 07 = '1': A warning has occurred.
Bit 08, Speed≠ reference/speed = reference:
Bit 08 = '0': The motor is running but the present speed is different from the preset speed reference. It might e.g. be the case when the speed ramps
up/down during start/stop. Bit 08 = '1': The motor speed matches the preset speed reference.
Bit 09, Local operation/bus control:
Bit 09 = '0': [STOP/RESET] is activate on the control unit or
converter via serial communication. Bit 09 = '1' It is possible to control the frequency converter via the fieldbus/ serial communication.
Bit 10, Out of frequency limit:
Bit 10 = '0': The output frequency has reached the value in par. 4-11
output frequency is within the defined limits.
Bit 11, No operation/in operation:
9
Bit 11 = '0': The motor is not running. Bit 11 = '1': The frequency converter has a start signal or the output frequency is greater than 0 Hz.
Bit 12, Drive OK/stopped, autostart:
Bit 12 = '0': There is no temporary over temperature on the inverter. Bit 12 = '1': The inverter stops because of over temperature but the unit does not
trip and will resume operation once the over temperature stops.
Bit 13, Voltage OK/limit exceeded:
Bit 13 = '0': There are no voltage warnings. Bit 13 = '1': The DC voltage in the frequency converter's intermediate circuit is too low or too high.
Bit 14, Torque OK/limit exceeded:
Bit 14 = '0': The motor current is lower than the torque limit selected in par. 4-18
Limit
is exceeded.
Bit 15, Timer OK/limit exceeded:
Bit 15 = '0': The timers for motor thermal protection and thermal protection are not exceeded 100%. Bit 15 = '1': One of the timers exceeds 100%.
NB!
All bits in the STW are set to '0' if the connection between the Interbus option and the frequency converter is lost, or an internal
communication problem has occurred.
9.6.3. Bus Speed Reference Value
Speed reference value is transmitted to the frequency converter in a rel-
ative value in %. The value is transmitted in the form of a 16-bit word;
in integers (0-32767) the value 16384 (4000 Hex) corresponds to 100%.
Negative figures are formatted by means of 2's complement. The Actual
Output frequency (MAV) is scaled in the same way as the bus reference.
