Bit 15: Enable_Driver –
“0” to disable the motor current, “1” to enable motor current. A valid configura-
tion must be written to the SD4840EK before the driver can be enabled.
Bit 14: Reserved –
Must be set to “0”.
Bit 13: OUT1_Set_State –
When the output is configured as a general purpose output point instead of the
Fault Output, this bit controls the state of the output. When this bit equals a “1”, the output is on and
conducts current.
Bit 12: Reserved –
Must be set to “0”.
Bit 11: Backplace_Proximity_Bit –
When the SD4840EK is configured to use the
Backplace_Proximity_Bit, the unit will ignore the state of the Home Input as long as this bit equals
“0”. This bit must equal “1” before a transition on the Home Input can be used to home the machine.
Further information on using the Backplace_Proximity_Bit can be found in the
Profile with Proxim-
ity Input
section found on page 51.
Bit 10: Clear_Driver_Fault –
If this bit is set when a Reset Errors Command is issued, (CMD_word0, Bit
10) the SD4840EK will attempt to clear driver errors. Note that the driver must be disabled
(CMD_word1, Bit 15 = 0), when using this command.
Bit 9: Assembled_Move_Type –
When this bit equals “0”, a Blend Move is started when the Run Assem-
bled Move bit, (CMD_word1, Bit 13) makes a 0

1 transition. When this bit equals “1”, a Dwell
Move is started on the transition. The direction of a Blend Move is controlled by the
Reverse_Blend_Direction bit, (CMD_word1, Bit 4). In a Dwell Move, the Dwell Time between seg-
ments is programmed with the UINT Jerk register of the command data.
Bit 8: Indexed_Command –
If this bit is set when a move command is issued, the SD4840EK will not run
the move immediately, but will instead wait for an inactive-to-active transition on an input config-
ured as a
Start Indexer Move
input.
Bit 7: Registration_Move –
When this bit equals “0”, and a Jog Move command is issued, it will run as a
standard Jog Move. When this bit equals “1” and a Jog Move command is issued, the move will run
as a Registration Move.
Bit 6: Enable_Electronic_Gearing –
Set to “1” to put the SD4840EK in Electronic Gearing mode. Set to
“0” for normal operation. A full description of Electronic Gearing mode starts on page 23.
Bit 5: Save_Assembled_to_Flash -
Set this bit to save the data of a programmed Assembled Move. This bit
is only acted upon this way when the Program_Assembled bit (CMD_word0, Bit 11 makes a 1

0
transition as explained in the
Assembled Move Programming
section of this manual starting on page
33.
