    GROUNDING The 05661 is internally grounded through the power cord to Earth Ground. However, any spindle connected to the Linear Amplifier must also be grounded. If this equipment is field installed, the installation instructions must be followed. Use the power cords and cables provided with the equipment;...

  • Page 7: General Information

    Operation of the 05661 can be controlled by a host computer via a GPIB or a RS-232 communication interface (Factory Option). If a host computer is not available or necessary, the 05661 can be completely controlled by its front panel controls without any degradation of its performance.

    Located on the front panel assembly is the LCD display controlled by the front panel CPU. The front panel assembly contains all the intelligence for the 05661 to operate in Local Mode. The front panel parses the GPIB communication and feeds it to the Main Electronics Assembly, where the Motor Controller CPU performs the task.

    OPERATING MODES The 05661 Linear Servo Amplifier has two major modes of operation: Local and Remote. Local Mode is usually used for maintenance, adjustments, and troubleshooting. Remote Mode is the normal operating mode when controlled by a host computer.

  • Page 10: Remote Mode

    05661 Linear Amplifier 1.6.2 REMOTE MODE Remote Mode is used when the 05661 is under the direction of a host computer. Parameters such as spindle RPM, direction, disk clamping, and run/stop commands are sent to the 05661 from a host computer via a GPIB or RS-232 communication interface.

    Input air pressure must not exceed 120 psi. ELECTRICAL CONNECTIONS AC power to the 05661 is determined by the factory. The AC power cable must have a ground wire and must connect the 05661 to the plant AC ground. Before connecting the AC power cable to the 05661, ensure that the power switch on the front panel is off.

    NOTE Should any of the 05661's assemblies not operate as stated, call Seagull Solutions's Field Services Division. POWER-UP SEQUENCE Startup Sequence for the 05661 requires two steps: 1.

  • Page 18: Applying Power

    NOTE On power-up of the 05661, the first time a RUN command is issued, the spindle will go through the auto-initialization routine. This ensures proper motor commutation. BASIC OPERATING MODES The 05661 has two basic modes of operation: Local and Remote.

  • Page 19: Remote Mode

    RPM. 4.3.2 REMOTE MODE Remote Mode is used when the 05661 is under the direction of a host computer. This is usually the case in media testers. Parameters such as spindle RPM, revolution direction, disk clamping, and spindle run/stop commands are sent to the controller from a host computer.
