FC 300 Design Guide 9. RS-485 Installation and Set-up
Bit 06, Start possible/Start not possible
Control word profile
If PROFIdrive has been selected in par. 8-10 , 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.
Bit 08, Speed ≠ reference / Speed = reference
When bit 08 = "0", the current speed of the motor deviates from the set speed reference value.
This may occur, for example, when the speed is being changed during start/stop through ramp
up/down.
When bit 08 = "1", the current speed of the motor corresponds to the set speed reference value.
Bit 09, Local operation/Bus control
Bit 09 = "0" indicates that the frequency converter has been stopped by means of the stop button
Reference
on the control panel, or that [Linked to hand] or [Local] has been selected in par. 3-13
site
.
When bit 09 = "1", the frequency converter 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
9
is within the indicated limits.
Bit 11, No operation/Operation
When bit 11 = "0", the motor does not turn.
When bit 11 = "1", the frequency converter 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 frequency converter
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 frequency converter are not exceeded.
When bit 13 = "1", the direct voltage in the intermediate circuit of the frequency converter 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 frequency converter
protection have not exceeded 100%.
When bit 15 = "1", one of the timers has exceeded 100%.
