Bit 7: Jog_CW – When this bit makes a 0

1 transition, the unit will run a Jog Move in the clockwise
direction. The full explanation of a CW/CCW Jog Move can be found starting on page 32.

Registration_Move – Command Word 1, Bit 7: 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: Find_Home_CCW – When this bit makes a 0

1 transition, the unit will attempt to find the Home
Limit Switch by beginning the move in the counter-clockwise direction. A full explanation of hom-
ing can be found in the
Homing an SMD34K reference chapter starting on page 51.
Bit 5: Find_Home_CW – When this bit makes a 0

1 transition, the unit will attempt to find the Home
Limit Switch by beginning the move in the clockwise direction. A full explanation of homing can be
found in the
Homing an SMD34K reference chapter starting on page 51.
Bit 4: Immediate_Stop – When this bit makes a 0

1 transition, the unit will stop all motion without
deceleration. The Motor Position value will become invalid if this bit is set during a move. Setting
this bit when a move is not in progress will not cause the Motor Position to become invalid.
When this command is issued, the SMD34K internally shorts the motor windings together to
dissipate any regeneration energy in the motor instead of sending it back through the power
supply. The motor windings are shorted for a maximum of 300 milliseconds. Once the short is
released on the windings, the SMD34K reestablishes current through the windings and sets the
Stopped bit (Word 0, bit 3) in the network input data.
Bit 3: Resume_Move –
When this bit makes a 0

1 transition, the unit will resume a move that you previ-
ously placed in a hold state. Use of the Resume_Move and Hold_Move bits can be found in the Con-
trolling Moves In Progress section of this manual starting on page 40. Note that a move in its hold
state need not be resumed. The move is automatically cancelled if another move is started in its
place.
Bit 2: Hold_Move –
When this bit makes a 0

1 transition, the unit will place a move in its hold state. The
move will decelerate to its programmed Starting Speed and stop. The move can be completed by
using the Resume_Move bit. Use of the
Hold_Move and Resume_Move bits can be found in the Con-
trolling Moves In Progress section of this manual starting on page 40.
Bit 1: Relative_Move –
When this bit makes a 0

1 transition, the unit will perform a Relative Move using
the data in the Command Parameters. The full explanation of a Relative Move can be found starting
on page 30.
Bit 0: Absolute_Move –
When this bit makes a 0

1 transition, the unit will perform an Absolute Move
using the data in the Command Parameters. The full explanation of an Absolute Move can be found
starting on page 31.
