RS-485 Installation and Set...
Make a selection in 8-55 Set-up Select to define how Bit 13
gates with the corresponding function on the digital
inputs.
Bit 15 Reverse
Bit 15 = '0': No reversing. Bit 15 = '1': Reversing. In the
default setting, reversing is set to digital in 8-54 Reversing
Select. Bit 15 causes reversing only when Ser. communi-
cation, Logic or or Logic and is selected.

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 24V 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. It might e.g. be
the case 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 activate on the control unit or
Local control in F-02 Operation Method is selected. You
cannot control the frequency converter via serial communi-
cation. 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
4-12 Motor Speed Low Limit [Hz] or 4-14 Motor Speed High
Limit [Hz]. 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 0Hz.
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.
