VLT Midi Drive FC 280
Bit 08, Speed reference/speed=reference
Bit 08=0: The motor runs, but the present speed is
different from the preset speed reference. It might happen
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: [Off/Reset] is activated on the control unit or [2]
Local in parameter 3-13 Reference Site is selected. It is not
possible to control the frequency converter via serial
communication.
5 5
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
parameter 4-12 Motor Speed Low Limit [Hz] or
parameter 4-14 Motor Speed High Limit [Hz].
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
without coast.
Bit 12, Frequency converter OK/stopped, auto start
Bit 12=0: There is no temporary overtemperature on the
frequency converter.
Bit 12=1: The frequency converter stops because of
overtemperature but the unit does not trip and resumes
operation once the overtemperature normalizes.
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 DC
link is too low or too high.
Bit 14, Torque OK/limit exceeded
Bit 14=0: The motor current is lower than the current limit
selected in parameter 4-18 Current Limit.
Bit 14=1: The current limit in parameter 4-18 Current Limit is
exceeded.
Bit 15, Timer OK/limit exceeded
Bit 15=0: The timers for motor thermal protection and
thermal protection are not exceeded 100%.
Bit 15=1: 1 of the timers exceeds 100%.
