The default digital speed reference selected when REMOTE is set to 1 will be

appropriate drive documentation.
Table 11-2 Control word bit definitions
Bit Function Description
b0 ENABLE
Set to 1 to enable the drive. Resetting to 0 will immediately disable the
drive, and the motor will coast to a stop. The external SAFE TORQUE
OFF signal must also be present before the drive can be enabled.
b1 RUN FWD
Set to 1 (with ENABLE set to 1) to run the motor in the forward
direction. When reset to 0, the drive will decelerate the motor to a
controlled stop.
b2 JOG FWD
Set to 1 to jog the motor forward. This signal needs to be used in
conjunction with the ENABLE bit. This signal is overridden by a RUN,
RUN REV or RUN FWD signal
b3 RUN REV
Set to 1 (with ENABLE set to 1) to run the motor in the reverse
direction. When reset to 0, the drive will decelerate the motor to a
controlled stop
b4 FWD/REV
Set to 1 to select the reverse direction. Set to 0 to run in the forward
direction. The RUN signal is used to start and stop the motor.
b5 RUN
Set to 1 to run the motor. FWD/REV is used to select the direction of
motor rotation. When reset to 0, the drive will decelerate the motor to a
controlled stop.
b6 NOT STOP
Set to 1 to allow the sequencing bit to be latched. If NOT STOP is zero,
all latches are cleared and held at 0.
b7 AUTO
Set to 1 to enable fieldbus control of the drive Control Word.
The Control Word Enable (Pr
06.043 ) must also be set to 1. When set
to 0, the drive will operate under terminal control.
b8 REMOTE
Set to 1 to select digital speed reference 1 (Pr 01.021 ), and set to 0 to
select analog reference 1 (Pr 01.036 ).
REMOTE directly controls Pr 01.042 , so reference selector (Pr 01.014 )
and preset selector (Pr 01.015 ) must both be set to 0 (default) for the
REMOTE bit to work properly.
b9 JOG REV
Set to 1 to jog the motor in reverse. This signal needs to be used in
conjunction with the ENABLE bit. This signal is overridden by a RUN,
RUN REV or RUN FWD command.
b10 Reserved
b11 Reserved
b12 TRIP
Set to 1 to trip the drive at any time. The trip display on the drive will be
‘Control Word’ and the trip code will be 35. AUTO (b7) has no effect on
this function. The trip cannot be cleared until TRIP is reset to 0.
b13 RESET
A 0 to 1 transition of the RESET bit will reset the drive from a trip
condition. If the reason for the trip is still present, or another fault has
been detected, the drive will immediately trip again.
When resetting the drive, it is recommended to check the status word
to ensure that the reset was successful, before attempting to re-start
the drive.
