Manual Control
The X-Series motion control products have an integrated, depressible knob with 20 detents per revolution,
allowing devices to be controlled without the use of a computer. There are two manual movement modes
available: Velocity and Displacement. Switch between these modes by holding down the knob for 1 second or
by configuring the knob.mode (T:109) setting.
On power-up, the device will only travel towards the motor from its start-up position until the home position
is reached. Once the device has been homed, the full range of travel becomes available.
Velocity Mode
Turn the knob clockwise to move the device in the positive direction (extend) or counter-clockwise for
negative direction (retract). Each detent of the knob increases the speed of the carriage.
There are 16 speeds in each direction. The velocity profile and maximum speed can be configured via the
knob.speedprofile (T:112) and knob.maxspeed (T:111) settings. The device stops and resets the knob upon
arriving at the end of travel.
Displacement Mode
Turn the knob clockwise to move the device in the positive direction (extend), counter-clockwise for negative
direction (retract). Each detent of the knob moves the device a fixed number of microsteps, specified by the
knob.distance (T:110) setting. If knob.distance (T:110) is set to 0, each detent of the knob will move to the
next index position, similar to move index (T:78) movements. The device moves at the speed specified by the
maxspeed (T:42) setting, or the slower of maxspeed (T:42) and limit.approach.maxspeed (T:41) if the device
has not been homed. If there are fewer than knob.distance (T:110) microsteps to the end of travel and another
move is requested, the device will move to the end of travel and then stop.
Summary of knob functionality
Turning the knob:
Moves the device in the direction of knob turn.
•
Pressing the knob:
Decelerates and stops the device (identical to a stop (T:23) command).
Instantly stops the device, if the device is already decelerating.
•
Pressing and holding the knob for 1 sec:
Toggles between Velocity Mode and Displacement Mode.
