  • Page 9: General Information

    GENERAL INFORMATION About the R eference Manual The MP-285 controller has been designed to fill the diverse needs of a wide range of applications in the life sciences, engineering, and commercial sectors. The MP-285 uses a system of menus, visualized on the controller display and accessed by keypad keystrokes, to provide for these varied uses.

  • Page 11: Input Devices

    The MP-285 is usually supplied with one of two input devices: a Rotary Optical Encoder (ROE) or a Joystick. Much of the operation of the MP-285 is dependent on the type of input device and how the device interacts with the controller to make the manipulator move. The following section describes the operation of each input device.

  • Page 12: Joystick

    Figure 1. Rotary Optical Encoder (ROE). Joystick The joystick provided with the MP-285 is a three-axis controller. A pair of handle movements controls each axis: left/right deflections, up/down deflections or clockwise/counter-clockwise twists. These movements are coupled to three potentiometers. The displacement of the joystick handle is transduced into an electrical analog output that is converted by the MP-285 controller into signals that drive the micromanipulator stepper motors.

  • Page 13: Adjustment Of Input Device Characteristics

    Adjustment of Input Device Characteristics As indicated, the response characteristics of each of the input devices are adjustable. The following list outlines the part of the controller menu and the corresponding part of the MP-285 manual which deals with each adjustment.

  • Page 14: Controller Configuration [Prgm]

FOR USERS OF THE JOYSTICK The MP-285 manipulator is designed so that the larger the deflection of the handle (on the joystick) the faster the movement of the manipulator. The controller handles this by converting the amount...

  • Page 16: Speed Range

    The functional effects of an increase in the speed range (i.e., slope of the velocity/deflection relationship) are: • An increase in the range of velocities that can be obtained within the limits of an input device’s deflection • A decrease in the resolution of velocity control MP-285 MICROMANIPULATOR REFERENCE MANUAL – REV. 3.10B (20070405)

  • Page 20: New Origin

    Any motor can be assigned to any of the input channels and hence to any input device motion control. The following diagram uses a rotary optical encoder to illustrate the relationship between the three input device motion controls, the three controller input channels, and the three manipulator motors: MP-285 MICROMANIPULATOR REFERENCE MANUAL – REV. 3.10B (20070405)
  • Page 21 Before attempting to change axes assignments it is important to understand the following: • The numbers (0…5) used in the axes menu refer to an MP-285 output channel and its polarity (direction of movement). Each pair of these channels is hard-wired to a motor: 0 and 1 = the X motor, 2 and 3 = the Y motor, and 4 and 5 = the Z motor (see Figure 8).

  • Page 22: Fourth (4 Th ) Axis Menu [Prgm\Setup\4 Th Axis]

    NOTE: The X, Y and Z coordinate labels on the refer to the output channels of the MP-285 controller. As stated above, each output channel is hardwired to a particular axis motor. The motors are then designated X, Y, and Z respectively. This relationship cannot be changed. This hard- wired arrangement may lead to confusion in certain configurations.

  • Page 27: Dead Zone

    The analog signal from each axis of the joystick is converted into a digital signal via individual A/D channels in the MP-285 controller. A digital value of 512 is produced if the joystick handle is at a neutral position (see [PRGM\Setup\Utilities\AD test]). Displacement of the joystick handle causes a corresponding increase or decrease depending on the direction of the handle displacement.

    The length of each individual µstep can be set by altering the “resolution of movement” setting (coarse or fine) and is adjusted as detailed in section Course/Fine Movement Resolution. µsteps/click can also be set from within the Configuration Menu (see section on PRGM\Continuous).

  • Page 40: Adjustment Of Parameters Effecting Continuous Movement (Joystick Users )

    An A/D interface in the MP-285 controller converts analog command signals from the input device into a digital output to the manipulator motors. The firmware installed in the MP-285 controller allows you to adjust four parameters related to this A/D conversion of the input signal.

    Up to 10 individual programmed robotic series can be saved and recalled. The MP-285 is an “open loop” system. There is no feedback of position information between the manipulator and controller except at the end of travel (EOT). The controller calculates the position of the manipulator based on the commands that it has sent.

    The easiest way to understand relative execution is by example. Imagine that you want to use the robotic capability of the MP-285 to methodically impale and micro-inject a large number of cells. The controller can easily be taught, via the “Learn” function, to make a patterned impalement motion.

  • Page 48: To Toggle Between Absolute And Relative Modes Of Robotic Program Execution

    L e a r n [ M OV E \* \ L e a rn ] Learn is used to “record” robotic movements which can then be executed later. The MP-285 is capable of storing up to 10 robotic programs or routines, each of which can contain up to 55 moves.
