Configuring the Ultra3000 Drive Chapter 3
• Home Sensor: An active state indicates to a homing sequence
that the sensor has been seen.
• Integrator Inhibit: An active state zeros the velocity loop
integrator.
• Negative Overtravel: An active state causes the drive to begin
decelerating the motor to bring it to a controlled stop in the
distance defined by the Negative Decel Distance as entered in
the drive window. The Negative HW Overtravel Input output is
set. The drive will not respond to further commands to move in
the negative direction, but can be instructed to move in the
positive direction to clear the negative overtravel condition.
• Operation Mode Override: When active, the drive uses the
Operation Mode Override as the command source. When
inactive, the drive uses the Operation Mode setting as the
command source.
• Pause Homing: An active state temporarily pauses a homing
sequence by decelerating to a stop. The state of the input is
continuously monitored to determine if the motion should be
stopped or if it may continue.
• Pause Index: An active state temporarily pauses an indexing
sequence by decelerating to a stop. The state of the input is
continuously monitored to determine if the motion should be
stopped or if it may continue.
• Position Strobe: An inactive state freezes the state of the motor
encoder outputs. A transition to an active state causes the drive
to output a continuous sequence of encoder counts until the
absolute position is reached on an external counter. This input is
used in conjunction with the Tracking output function.
• Positive Overtravel: An active state causes the drive to begin
decelerating the motor to bring it to a controlled stop in the
distance defined by the Positive Decel Distance as entered in
the drive window. The Positive HW Overtravel Input output is
set. The drive will not respond to further commands to move in
the positive direction, but can be instructed to move in the
negative direction to clear the positive overtravel condition.
• Preset Select 0 to 5: Used in combination to assign a Preset
Current, Preset Velocity, Preset Position, Preset Follower Gearing
Ratio or Index. Refer to the binary preset explanation, beginning
on
page .
Note: The drive uses only Preset Select 0, 1 and 2 (yielding
values 0-7) when selecting a Preset Position, Preset Velocity,
Preset Current or Preset Follower (Gearing Ratio).
• Registration Sensor: A transition to an active state adjusts a
registration indexing move in progress. If the Registration
Sensor input is seen, the move is adjusted so that the end
position is the amount specified by the Registration Distance
parameter after the position where the Registration Sensor
input was seen.
Note: The Registration Distance must be larger than the
distance required to stop, or the move is not adjusted.
• Remove Command Offset: A transition to an active state causes
the offset of the analog COMMAND input to be measured (after
averaging), and sets the Current COMMAND Input Offset,
Position COMMAND Input Offset and Velocity COMMAND Input
Offset parameters to the negative of this value.
• Reset Drive: A transition to an active state causes the drive to do
a drive reset.
If Ultraware software is displaying the drive when this occurs, it
may report a loss of communication with the drive.
