Table 7.37 Status Bits
Explanation of the Status Bits
Bit 00, Control not ready/ready:
Bit 00 = ’0’: The frequency converter trips. Bit 00 = ’1’: The
frequency converter 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 frequency converter 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 frequency converter releases the motor. Bit
02 = ’1’: The frequency converter starts the motor with a
start command.
Bit 03, No error/trip:
Bit 03=’0’ : The frequency converter is not in fault mode.
Bit 03 = ’1’: The frequency converter trips. To re-establish
operation, enter [Reset].
Bit 04, No error/error (no trip):
Bit 04=’0’: The frequency converter is not in fault mode. Bit
04 = “1”: The frequency converter 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 frequency converter is not in fault mode. Bit
06 = “1”: The frequency converter 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. This can occur
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’: [STOP/RESET] is activated on the control unit or
Local control in F-02 Operation Method is selected. It is
impossible 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
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.
