Table 4.7 Status Bits
Explanation of the status bits
Bit 00, Not ready to switch on/ready to switch on:
Bit 00 = 0 state less than Ready to switch on.
Bit 00 = 1 state at least = Ready to Switch on.
Bit 01, Switch o/switch on:
Bit 00 = 0 state less than switched on.
Bit 00 = 1 state at least = switched on.
Bit 02, Operation disable/operation enable:
Bit 00 = 0 state less than operation enable.
Bit 00 = 1 state at least = operation enable.
Bit 03, No fault/trip:
Bit 03 = 0 means that the frequency converter is not in a
fault condition.
Bit 03 = 1 means that the frequency converter has tripped
and needs a reset signal to run.
Bit 04, Voltage disable/voltage enable:
Bit 04 = 0 means that control word bit 01 = 1.
Bit 04 = 1 means that control word bit 01 = 0.
Bit 05, Quick stop/run:
Bit 05 = 0 means that control word bit 02 = 1.
Bit 05 = 1 means that control word bit 02 = 0.
Bit 06, Start enable/start disable:
Bit 06 = 0 state is not switch on disable.
Bit 06 = 1 state is switch on enable.
Bit 07, No warning/warning:
Bit 07 = 0 means that there is no warning. situation.
Bit 07 = 1 means that a warning has occurred.
Bit 08
Danfoss reserved.
Bit 09, Remote disable/remote enable:
Bit 09 = 0 means that the frequency converter has been
stopped with the [stop] key on the LCP, or that [Local] has
been selected in parameter 3-13 Reference Site.
Bit 09 = 1 means that it is possible to control the
frequency converter via the serial port.
Bit 10, Setpoint not reached/setpoint reached:
Bit 10 = 0 means that the actual motor speed is dierent
from the speed reference set. This can be the case while
the speed is ramped up/down during start/stop.
Bit 10 = 1 means that the present motor speed equals the
speed reference set.
Bit 11, Speed limit not active/speed limit active:
Bit 11 = 0 means that the output frequency is out of the
range set in parameter 4-11 Motor Speed Low Limit [RPM]/
parameter 4-12 Motor Speed Low Limit [Hz] or
parameter 4-13 Motor Speed High Limit [RPM]/
parameter 4-14 Motor Speed High Limit [Hz].
Bit 11 = 1 means that the output frequency is within the
mentioned range.
Bit 12
DSP 402 reserved.
Bit 13
DSP 402 reserved.
Bit 14, Running/not running:
Bit 14 = 0 means that the motor is not running.
Bit 14 = 1 means that the frequency converter has a valid
start signal or that the output frequency is greater than 0
Hz.
Bit 15
Danfoss reserved.
