Groups
Bit 00, Control not ready/ready:
Bit 00 = "0" means that the control word's
bit 00, 01 or 02 = "0" (OFF1, OFF2 or
OFF3), or the VLT ® frequency converter
has tripped. Bit 00 = "1" means that the
®
VLT frequency converter is ready to
operate when it receives the necessary
start signals.
Big 01, VLT ® not ready/ready:
Same significance as bit 00.
Bit 02, Free-wheeling/possible:
Bit 02 = "0" means that the control word's
bit 00, 02 or 03 = "0" (OFF1, OFF2 or
OFF3 or Free-wheeling), or the VLT
frequency converter has tripped. Bit 02 =
"1" means that the control word's bit 00,
01, 02 and 03 = "1", and the VLT
quency converter has not tripped.
Bit 03, No fault/trip:
Bit 03 = "0" means that the VLT
converter is not in a fault status. Bit 03 =
®
"1" means that the VLT
verter has tripped and it requires a reset
signal before it can run.
Bit 04, ON2/OFF2:
Bit 04 = "0" means that the control word's
bit 01 = "1".
Bit 04 = "1" means that the control word's
bit 01 = "0".
Bit 05, ON3/OFF3:
Bit 05 = "0" means that the control word's
bit 02 = "1".
Bit 05 = "1" means that the control word's
bit 02 = "0".
Bit 06, Start possible/not possible:
Bit 06 is always "0" if "Start not possible"
[11] has not been selected in parameter
309. When "Start not possible" [11] is se-
lected in parameter 309, bit 06 will be "1"
after reset of a trip, after activation of OFF2
or OFF3 and after connection of mains
voltage. "Start not possible" is reset, the
control word's bit 00 being set at "0" and bit
01, 02 and 10 at "1".
Bit 07, No warning/warning:
Bit 07 = "0" means that there is no extra-
ordinary situation. Bit 07 = "1" means that
an abnormal status has arisen for the
®
VLT frequency converter. All warnings
described on pp. 124-125 will set bit 07
at "1".

Bit 08, Speed in ref./speed = ref.:
Bit 08 = "0" means that the motor's cur-rent
speed is different from the set speed
reference. This can e.g. be the case while
the speed is ramped up/down on start/stop.
Bit 08 = "1" means that the motor's current
speed is equal to the set speed reference.
Bit 09, Local control/bus control:
Bit 09 = "0" means that the VLT
cy converter has stopped with the help of
the stop key on the operating panel, or
"local" or "local with external free-wheeling
stop" has been selected in parameter 003.
Bit 09 = "1" means that it is possible to
® control the VLT
the serial port.

fre- Bit 10, Out of range/frequency OK:
Bit 10 = "0" means that the output frequen-
cy is outside the limits set in parameter 210
(Warning: Low frequency) and parameter
® frequency 211 (Warning: High frequency). Bit 10 = "1"
means that the output frequency is within
the aforementioned limits.
frequency con-
Bit 11, Not running/running:
Bit 11 = "0" means that the motor is not
running. Bit 11 = "1" means that the VLT
frequency converter has a start signal or
the output frequency is greater than 0.5 Hz.
Bit 12, VLT
Bit 12 = "0" means that there is no tem-
porary overload of the inverter. Bit 12 = "1"
means that the inverter has stopped due to
overload, but the VLT
verter has not tripped and it will continue
when the overload disappears.
Bit 13, OK/over/undervoltage:
Bit 13 = "0" means that the VLT
cy converter's voltage limits have not been
exceeded. Bit 13 = "1" means that the D.C.
voltage in the VLT
intermediate circuit is too low or too high.
Bit 14, Current OK/above limit:
Bit 14 = "0" means that the motor current is
lower than the current limit selected in
parameter 209. Bit 14 = "1" means that the
current limit in parameter 209 has been
exceeded.
