Explanation of the Status Bits
Bit 00, Control not ready/ready:
Bit 00 = ’0’: The adjustable frequency drive trips. Bit 00
= ’1’: The adjustable frequency drive controls are ready but
the power component does not necessarily receive any
power supply (in case of external 24 V supply to controls).
Bit 01, Drive ready:
Bit 01 = ’1’: The adjustable frequency drive is ready for
operation but the coasting command is active via the
digital inputs or via serial communication.
Bit 02, Coasting stop:
Bit 02 = ’0’: The adjustable frequency drive releases the
motor. Bit 02 = ’1’: The adjustable frequency drive starts
the motor with a start command.
Bit 03, No error/trip:
Bit 03 =’0’: The adjustable frequency drive is not in fault
mode. Bit 03 = ’1’: The adjustable frequency drive trips. To
re-establish operation, enter [Reset].
Bit 04, No error/error (no trip):
Bit 04 = ’0’: The adjustable frequency drive is not in fault
mode. Bit 04 = “1”: The adjustable frequency drive shows
an error but does not trip.
Bit 05, Not used:
Bit 05 is not used in the status word.
Bit 06, No error / triplock:
Bit 06 = ’0’: The adjustable frequency drive is not in fault
mode. Bit 06 = “1”: The adjustable frequency drive is
tripped and locked.
Bit 07, No warning/warning:
Bit 07 = ’0’: There are no warnings. Bit 07 = ’1’: A warning
has occurred.
Bit 08, Speed≠ reference/speed = reference:
Bit 08 = ’0’: The motor is running but the present speed is
different from the preset speed reference. For example, if
the speed accels/decels during start/stop. Bit 08 = ’1’: The
motor speed matches the preset speed reference.
Bit 09, Local operation/bus control:
Bit 09 = ’0’: [STOP/RESET] is activated on the control unit
or
Local control in F-02 Operation Method is selected. You
cannot control the adjustable frequency drive via serial
communication. Bit 09 = ’1’ It is possible to control the
adjustable frequency drive via the network/serial communi-
cation.
Bit 10, Out of frequency limit:
Bit 10 = ’0’: The output frequency has reached the value in
F-18 Motor Speed Low Limit [RPM] or F-17 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
adjustable frequency drive has a start signal, or the output
frequency is greater than 0 Hz.
Bit 12, Drive OK/stopped, autostart:
Bit 12 = ’0’: There is no temporary over temperature on
the inverter. Bit 12 = ’1’: The inverter stops because of over
temperature but the unit does not trip and will resume
operation once the over temperature stops.
