FC 300 Design Guide 9. RS-485 Installation and Set-up
Bit 09, Local operation/Bus control
Bit 09 = "0" indicates that the adjustable frequency drive has been stopped by means of the stop
button on the control panel, or that [Linked to hand] or [Local] has been selected in par. 3-13

.
When bit 09 = "1", the adjustable frequency drive can be controlled through the serial interface.
Bit 10, Out of frequency limit/Frequency limit OK
Motor speed low
When bit 10 = "0", the output frequency is outside the limits set in par. 4-11
limit (rpm) Motor speed high limit (rpm)
and par. 4-13 . When bit 10 = "1", the output frequency
is within the indicated limits.
Bit 11, No operation/Operation
When bit 11 = "0", the motor does not turn.
When bit 11 = "1", the adjustable frequency drive has a start signal, or the output frequency is
higher than 0 Hz.
Bit 12, Drive OK/Stopped, autostart
When bit 12 = "0", there is no temporary overloading of the inverter.
When bit 12 = "1", the inverter has stopped due to overloading. However, the adjustable fre-
quency drive has not switched off (trip) and will start again after the overloading has ended.
Bit 13, Voltage OK/Voltage exceeded
When bit 13 = "0", the voltage limits of the adjustable frequency drive are not exceeded.
When bit 13 = "1", the direct voltage in the intermediate circuit of the adjustable frequency drive
is too low or too high.

Bit 14, Torque OK/Torque exceeded
Torque limit motor
When bit 14 = "0", the motor torque is below the limit selected in par. 4-16
mode Torque limit generator mode
and par. 4-17 . When bit 14 = "1", the limit selected in par.
Torque limit motor mode Torque limit generator mode
4-16 or par. 4-17 is exceeded.
Bit 15, Timer OK/Timer exceeded
When bit 15 = "0", the timers for the thermal motor protection and thermal adjustable frequency
drive protection have not exceeded 100%.
When bit 15 = "1", one of the timers has exceeded 100%.
