Motorized Labjack
Chapter 5 Standalone Operation
5.1 Introduction
The MLJ150 lab jack offers a fully featured motion control capability including velocity
profile settings, limit switch handling, and homing sequences. When the unit is
connected to the PC, these parameters are automatically set to allow “out of the box”
operation with no further “tuning” required. However, further adjustment is possible
via the Kinesis Server software - see Chapter 6.
The following brief overview explains how the top panel controls can be used to
perform a typical series of motor moves.
In conjunction with this chapter, it also may be useful to read the background on
stepper motor operation contained in Appendix C.
5.2 Top Panel Controls and Indicators
Fig. 5.1 Front Panel Controls and Indicators
MOVE Controls -
These controls allow all motor moves to be initiated.
Jog Buttons
- Used to jog the motors and make discrete position increments in
either direction (left button up, right button down) - see Section 6.6. for more
details on jogging.
Slider Potentiometer
- Used to drive the motor at a pre-defined speed in either
forward or reverse directions for full and easy motor control - see Section 5.3.
ACTIVE LED
- The Active LED will flash when the motor reaches a forward or reverse
limit switch, and is lit when the motor is moving.
POWER LED -
When the stage is enabled, this LED is lit. Furthermore, this LED will
flash when the ‘Ident’ button is clicked on the Kinesis GUI panel.
Warning
As the unit is raised and lowered, items can become trapped in the mechanism.
During operation, keep fingers, clothing and tools away from any moving parts.
