FC 300 Design Guide
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 Local control in par. 3-13 Reference Site is
selected. You cannot control the frequency 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 Motor Speed Low Limit or par. 4-13
Motor Speed High Limit. Bit 10 = "1": The output frequency is within the defined limits.
Bit 11, No operation/in operation:
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 temper-
ature 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 Current Limit. Bit 14
= '1': The torque limit in par. 4-18 Current Limit is exceeded.
Bit 15, Timer OK/limit exceeded:
Bit 15 = '0': The timers for motor thermal protection and VLT 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 fre-
quency converter is lost, or an internal communication problem has occurred.
