Bit 00, Control not ready/ready:
Bit 00 = "0" means that bit 00, 01 or 02 of the
control word is "0" (OFF1, OFF2 or OFF3), or that the
frequency converter has tripped. Bit 00 = "1" means
that the frequency converter control is ready.
Bit 01, FC not ready/ready:
Same meaning as bit 00; however, there is also a supply
to the power section, and the frequency converter is
ready to run when it receives the necessary start signals.
Bit 02, Coasting/enable:
Bit 02 = "0" means that the control word bit 00, 01,
02 or 03 is "0" (OFF1, OFF2, OFF3 or Coasting), or
the FCM 300 Series unit has tripped. Bit 02 = "1"
means that the control word bits 00, 01, 02 or 03 are
"1" and that the FC motor has not tripped.
Bit 03, No fault/trip:
Bit 03 = "0" means that FCM 300 Series is not in a fault
condition. Bit 03 = "1" means that FCM 300 Series has
tripped and needs a reset signal in order to run.
Bit 04, ON2/OFF2:
Bit 04 = "0" means that control word bit 01 = "1". Bit
04 = "1" means that control word bit 01 = "0".
Bit 05, ON3/OFF3:
Bit 05 = "0" means that control word bit 02 = "1". Bit
05 = "1" means that control word bit 02 = "0".

Bit 06, Start enable/start disable:
Bit 06 is always "0" if FC Drive has been selected
in parameter 512. If Profidri v e has been selected in
parameter 512, bit 06 will be "1" after reset of a trip,
after activation of OFF2 or OFF3 and after connection
of mains voltage. Start disable is reset, setting control
word bit 00 to "0" and bits 01, 02 and 10 to "1".
Bit 07, No warning/warning:
Bit 07 = "0" means that there is no unusual situation. Bit
07 = "1" means that an abnormal condition has arisen
for the FC motor. All warnings described in section List
of warnings and alarms will set bit 07 to "1".
Bit 08, Speed ≠ ref/speed. = ref.:
Bit 08 = "0" means that the actual motor speed is
different from the speed reference set. This can be
the case i.a. while the speed is ramped up/down
during start/stop. Bit 08 = "1" means that the present
motor speed equals the speed reference set.
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 201Output 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, Not running/running:
Bit 11 = "0" means that the motor is not running. Bit
11 = "1" means that the FC motor has a start signal or
that the output frequency is greater than 0 Hz.
Bit 13, Voltage OK/above limit:
Bit 13 = "0" means that the voltage limits of the
FC motor have not been exceeded. Bit 13 =
"1" means that the DC voltage of the FC motor
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
221. Bit 14 = "1" means that the current limit in
parameter 221 has been exceeded.
Bit 15, Thermal warning:
