Table 4.6 Status Bits
Explanation of the status bits:
Bit 00, Not ready to switch on/ready to switch on
Bit 00 = 0: The state is less than ready to switch on.
Bit 00 = 1: The state is at least equal to ready to switch on.
Bit 01, Switch off/switch on
Bit 00 = 0: The state is less than switched on.
Bit 00 = 1: The state is at least equal to switched on.
Bit 02, Operation disable/operation enable
Bit 00 = 0: The state is less than operation enable.
Bit 00 = 1: The state is at least equal to operation enable.
Bit 03, No fault/trip
Bit 03 = 0: The frequency converter is not in a fault
condition.
Bit 03 = 1: The frequency converter has tripped and needs
a reset signal to run.
Bit 04, Voltage disable/voltage enable
Bit 04 = 0: Control word bit 01 = 1.
Bit 04 = 1: Control word bit 01 = 0.

Bit 05, Quick stop/run
Bit 05 = 0: Control word bit 02 = 1.
Bit 05 = 1: Control word bit 02 = 0.
Bit 06, Start enable/start disable
Bit 06 = 0: The state is not switch on disable.
Bit 06 = 1: The state is switch on disable.
Bit 07, No warning/warning
Bit 07 = 0: There is a no-warning situation.
Bit 07 = 1: A warning has occurred.
Bit 08, Speed ≠ reference/speed = reference
Bit 08 = 0: The motor is running, but the current speed is
different from the speed reference. This is the case when,
for example, the speed is being ramped up or down.
Bit 08 = 1: The current speed matches the speed reference.
Bit 09, Remote disable/remote enable
Bit 09 = 0: The frequency converter is stopped with the
[Stop] key on the LCP, or [Local] is selected in
parameter 3-13 Reference Site.
Bit 09 = 1: It is possible to control the frequency converter
via the serial port.
Bit 10, Setpoint not reached/setpoint reached
Bit 10 = 0: The actual motor speed is different from the
speed reference. This is the case when, for example, the
speed is being ramped up or down.
Bit 10 = 1: The present motor speed equals the speed
reference.
Bit 11, Speed limit not active/speed limit active
Bit 11 = 0: The output frequency is outside 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: The output frequency is within the limits.
Bit 12
Reserved for DSP 402.
Bit 13
Reserved for DSP 402.
Bit 14, Running/not running
Bit 14 = 0: The motor is not running.
Bit 14 = 1: The frequency converter has a valid start signal
or the output frequency is greater than 0 Hz.
Bit 15
Reserved for the frequency converter.
4.3.5 Reference Handling
In DSP 402 profile, the reference (object 6042h) is in RPM
by default. To use a different unit, set the vl dimension
factor (object 604Ch) to a value other than 1. Refer to the
DSP 402 standard for details.
