Bit 08, Speed reference/speed = reference
Bit 08="0" - the motor is running, but that the present
speed is different from the preset speed reference. It could,
for example, be the case while the speed is being ramped
up/down during start/stop.
Bit 08="1" - the present motor present speed matches the
preset speed reference.
Bit 09, Local operation/bus control
Bit 09="0" - [Stop/Reset] is activated on the control unit, or
that Local control in 3-13 Reference Site is selected. It is not
possible to control the frequency converter via serial
communication.
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
4-11 Motor Speed Low Limit [RPM] or 4-13 Motor Speed High
Limit [RPM].
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 or
the output frequency is greater than 0 Hz.
Bit 12, frequency converter OK/stopped, auto start
Bit 12="0" - there is no temporary over temperature on the
frequency converter.
Bit 12="1" - the frequency converter has stopped because
of over temperature, but the unit has not tripped and
resumes operation once the over temperature stops.
Bit 13, Voltage OK/limit exceeded
Bit 13="0" - there are no voltage warnings.
Bit 13="1" - the DC voltage in the frequency converters
intermediate circuit is too low or too high.
Bit 14, Torque OK/limit exceeded
Bit 14="0" - the motor current is lower than the torque
limit selected in 4-16 Torque Limit Motor Mode or
4-17 Torque Limit Generator Mode.
Bit 14="1" - the torque limits in 4-16 Torque Limit Motor
Mode and 4-17 Torque Limit Generator Mode have been
exceeded.
Bit 15, Timer OK/limit exceeded
Bit 15="0" - the timers for motor thermal protection and
VLT thermal protection, respectively, have not exceeded
100%.
Bit 15="1" - one of the timers has exceeded 100%.
