FCD Series
Bit 04, Not used:
Bit 04 is not used in the status word.
Bit 05, Not used:
Bit 05 is not used in the status word.
Bit 06, Trip lock:
Bit 06 =
’
0
’
means that the frequency converter
is not trip locked.
Bit 06 =
’
1
’
means that the frequency converter
is trip locked and it cannot be reset before the
mains supply has been removed. The trip can be
reset either with 24 V external control back up or
after the power is connected again.
Bit 07, No warning/warning:
Bit 07 =
’
0
’
means that there are no warnings.
Bit 07 =
’
1
’
means that a warning has occurred.
Bit 08, Speed
≠
ref/speed = ref.:
Bit 08 =
’
0
’
means that the motor is running, but that
the present speed is different from the preset speed
reference. It might, for example, be the case while the
speed is being ramped up/down during start/stop.
Bit 08 =
’
1
’
means that the motor
’
s present speed
is the same as the preset speed reference.
Bit 09, Local operation/serial communication control:
Bit 09 =
’
0
’
means that [STOP/RESET] is activated on
the control unit, or that
Local control
in parameter
002
Local/remote operation
is selected. It is
not possible to control the frequency converter
via serial communication.
Bit 09 =
’
1
’
means that it is possible to control the
frequency converter via serial communication.
Bit 10, Outside frequency range:
Bit 10 =
’
0
’
, if the output frequency has reached
the value in parameter 201
Output frequency
low limit
or parameter 202
Output frequency
high limit
. Bit 10 = "1" means that the output
frequency is within the defined limits.
Bit 11, Running/not running:
Bit 11 =
’
0
’
means that the motor is not running.
Bit 11 =
’
1
’
means that the frequency converter
has a start signal or that the output frequency
is greater than 0 Hz.
Bit 13, Voltage warning high/low:
Bit 13 =
’
0
’
means that there are no voltage warnings.
Bit 13 =
’
1
’
means that the DC voltage in the frequency
converter
’
s intermediate circuit is too low or too high.
Bit 14, Current limit:
Bit 14 =
’
0
’
means that the output current is less than
the value in parameter 221
Current Limit I
LIM
.
Bit 14 =
’
1
’
means that the output current is
greater than the value in parameter 221
Current
LimitI
LIM
and that the frequency converter will
trip after a set period of time.
Bit 15, Thermal warning:
Bit 15 =
’
0
’
means that there is no thermal warning.
Bit 15 =
’
1
’
means that the temperature limit has been
exceeded in either the motor, frequency converter or
from a thermistor that is connected to a digital input.
■
Fast I/O FC-profile
The
Fast I/O FC-profile
can be used to monitor the
digital inputs just by reading the status word. The
input status in the status word reflects the actual
input state (High or Low) regardless of the selected
digital input function. The fast I/O profile(s) will
only be available in drives fitted with Profibus. The
response time from input changes until it is available
on the Profibus is approximately 10 mS.
