å Status Word Bit Description for VLT 2800
The status word is used to inform the master
(e.g. a PC) of the slave’s (frequency converter)
mode. Slave Master.
Bit Bit = 0 Bit =1
00 Control ready
01 Drive ready
02 Coasting stop
03 No trip Trip
04 Not used
05 Not used
06 Trip lock
07 No warning Warning
08 Speed ≠ ref. Speed = ref.
09 Local control Ser. communi.
10 Outside
frequency range
Frequency limit
OK
11 Motor running
12
13 Voltage warn.
14 Current limit
15 Thermal warn.
Bit 00, Control ready:
Bit 00 = ’1’. The frequency converter is
ready for operation.
Bit 00 = ’0’. The frequency converter is not
ready for operation.
B
it 01, Drive ready:
Bit 01 = ’1’. The frequency converter is ready for
operation, but there is an active coasting command
via the digital inputs or via serial communication.
B
it 02, Coasting stop:
Bit 02 = ’0’. The frequency converter has
released the motor.
Bit 02 = ’1’. The frequency converter can start the
motor when a start command is given.
B
it 03, No trip/trip:
Bit 03 = ’0’ means that the frequency converter
is not in fault mode.
Bit 03 = ’1’ means that the frequency converter
is tripped, and that it needs a reset signal for
operation to be reestablished.
B
it 04, Not used:
Bit04isnotusedinthestatusword.
B
it 05, Not used:
Bit05isnotusedinthestatusword.
B
it 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.
B
it 07, No warning/warning:
Bit 07 = ’0’ means that there are no warnings.
Bit 07 = ’1’ means that a warning has occurred.
B
it 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.
B
it 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.
B
it 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.
