4. How to Control the Frequency Converter
Bit 07 = '1' means that a warning has occurred.
Bit 08, Speed ≠ reference/speed = reference:
Bit 08 = '0' means that the motor is running, but that the present speed is different from the
preset speed reference. It might, for example, be the case while the speed is being ramped up/
down during start/stop.
Bit 08 = '1' means that the present motor present speed matches the preset speed reference.
Bit 09, Local operation/bus control:
Bit 09 = '0' means that [STOP/RESET] is activated on the control unit, or that Local control in par.

communication.
Bit 09 = '1' means that it is possible to control the frequency converter via the fieldbus/ serial
communication.
Bit 10, Out of frequency limit:
Bit 10 = '0', if the output frequency has reached the value in par. 4-11
par. 4-13
Bit 10 = "1" means that the output frequency is within the defined limits.
Bit 11, No operation/in operation:
Bit 11 = '0' means that the motor is not running.
Bit 11 = '1' means that the frequency converter has a start signal or that the output frequency is
greater than 0 Hz.
Bit 12, Drive OK/stopped, auto start:
Bit 12 = '0' means that there is no temporary over temperature on the inverter.
Bit 12 = '1' means that the inverter has stopped because of over temperature, but that the unit
has not tripped and will resume operation once the over temperature stops.
Bit 13, Voltage OK/limit exceeded:
Bit 13 = '0' means that there are no voltage warnings.
Bit 13 = '1' means that 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' means that the motor current is lower than the torque limit selected in par. 4-16
Torque Limit Motor Mode
Bit 14 = '1' means that the torque limit in par. 4-16 and 4-17 has been exceeded.
Bit 15, Timer OK/limit exceeded:
Bit 15 = '0' means that the timers for motor thermal protection and VLT thermal protection, re-
spectively, have not exceeded 100%.
Bit 15 = '1' means that one of the timers has exceeded 100%.
