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, Torque OK/above limit:
Bit 14 = "0" means that the motor current is lower
than the torque limit selected in parameter 221. Bit
14 = "1" means that the torque limit in parameter
221 has been exceeded.
Control word under VLT standard (parameter 512 =
FC Drive)
The control word is used for sending commands from
a master (e.g. a PC) to a slave (FC motor).

programmed references (parameters 215-216) in
accordance with the following table:

Bit 15, Timers OK/above limit:
Bit 15 = "0" means that the timers for motor thermal
protection and VLT thermal protection, respectively,
have not exceeded 100%. Bit 15 = "1" means that
one of the timers has exceeded 100%.
NB!
Parameter 508 is where to choose the way
bits 1/12 are to be combined (gated) with the
corresponding function on the digital inputs.
Bit 02, DC brake:
Bit 02 = "0" leads to DC braking and stop. Braking
current and duration are set in parameters 132 and
133. Bit 02 = "1" leads to ramp.
Bit 08, Activation of Jog speed in parameter 213:
Bit 08 = "0": Jog speed not activated. Bit 08 = "1"
means that the motor is running at Jog speed.
Bit 11, Output
Bit 11 = "0": Output not activated. Bit 11 = 1:
Output activated, provided Off 123 has been chosen
in parameter 340.
See the description of other bits under control word
for Profidrive standard, page 78.
NB!
Unless otherwise mentioned, the control
word bit is combined (gated) with the
corresponding function on the digital inputs as a
logic "or" function.
