How to Control the FC 300
Bit 06, Start possible/Start not possible
If PROFIdrive has been selected in par. 8-10 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.
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 on the
control panel, or that [Linked to hand] or [Local] has been selected in par. 3-13 Reference site.
When bit 09 = "1", the frequency converter can be controlled through the serial interface.
Bit 10, Out of frequency limit/Frequency limit OK
When bit 10 = "0", the output frequency is outside the limits set in par. 4-11 Motor speed low limit (rpm) and
par. 4-13 Motor speed high limit (rpm). 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 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
When bit 14 = "0", the motor torque is below the limit selected in par. 4-16 Torque limit motor mode and
par. 4-17 Torque limit generator mode. When bit 14 = "1", the limit selected in par. 4-16 Torque limit motor
mode or par. 4-17 Torque limit generator mode 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%.
