Bit 08, Jog
Bit 08 = "1" causes the output frequency to be determined
by C-21 Jog Speed [RPM].

Bit 09, Selection of ramp 1/2
Bit 09 = "0" means that ramp 1 is active
Bit 09 = "1" means that ramp 2 is active.

Bit 10, Data not valid/Data valid
Is used to tell the frequency converter whether the control
word is to be used or ignored. Bit 10 = "0" causes the
control word to be ignored.
Bit 10 = "1" causes the control word to be used. This
function is relevant, because the control word is always
contained in the message, regardless of which type of
message is used, i.e. it is possible to turn off the control
word if you do not wish to use it in connection with
updating or reading parameters.

Bit 11, Relay 01
Bit 11 = "0" Relay not activated.
Bit 11 = "1" Relay 01 activated, provided Control word bit
11 has been chosen in E-24 Function Relay.

Bit 12, Relay 04
Bit 12 = "0" Relay 04 has not been activated.
Bit 12 = "1" Relay 04 has been activated, provided Control
word bit 12
has been chosen in E-24 Function Relay.

Bit 13/14, Selection of set-up
Bits 13 and 14 are used to choose from the four menu set-
ups according to Table 6.11:

The function is only possible when Multi-Set-ups is selected
in K-10 Active Set-up.

Table 6.11

In O-55 Set-up Select a selection is made to define how Bit
13/14 gates with the corresponding function on the digital
inputs.

Bit 15 Reverse
Bit 15 = "0" causes no reversing.
Bit 15 = "1" causes reversing.

6.5.2 Status Word according to GE Drive

Profile (STW)

The status word is used to inform the master (e.g. a PC) of
the operation mode of the slave (frequency converter).

Please refer to 9 Application Examples for an example of a
status word message using PPO type 3.

Explanation of the Status Bits

Bit 00, Control not ready/ready
Bit 00 = "0" means that the frequency converter has
tripped.
Bit 00 = "1" means that the frequency converter controls
are ready, but that the power component is not necessarily
receiving any power supply (in case of external 24V supply
to controls).

Bit 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.

Bit 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.

Bit 03, No error/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 a reset signal is required to re-establish operation.
