Now you can remove the board. It also adjusts offsets, signal amplitudes, and loop gains AGCsto enlarge system robustness and to avoid expensive potentiometer adjustments in production.

Activate the terminal emulation program and check that the port settings for the free COM port are: The two hall outputs, which go to the PCS datasheey block, are ‘sin phi’ and ‘cos phi’.

A normal DC motor is used, combined with hall sensors. Whatever your manufacturing need, come to 1-Source to ha5938fm electric components from the leading electronic component distributors and electronic component suppliers! This action is signalised by the internal engine controller and reported to the application. The digital codes are then applied to logic circuitry to obtain the various control signals. They drive the motor IC item In addition, we provide excess inventory consignment, electronic engineering and product design services, prototyping, contract manufacturing, handheld portable computing products, and software application development services.

Its main task is normalisation of the servo signals that go to the MACE3 servo processor signals like ‘focus servo’, ‘radial servo’, ‘track loss servo’, and ’tilt sensor’. See also the internal block diagram at the end of this chapter. Unplug the mains cord, and connect a wire between the two pins of the mains plug. The supplies can be delivered separately to obtain maximum output performance of the TZA in environments with large and highly dynamic current flows.


Some of them are datadheet to adjust the servo error signals once per disc rotation. Find part number s: Driver Servo Board Progressive Scan Board 7.

Measure the resistance value between the mains plug and the front panel, controls, and chassis bottom. The conversion frequency is 88KHz per channel. We will gladly help you locate any Electronic or Electrical Parts.

ddatasheet This sequence is done twice – first a coarse calibration, followed by a fine-tuning. Contact us to buy or sell excess electronic component parts and inventory.

This is also valid for the Basic Engine. Processor Diagram 1 25 Servo Board The commands that can be given are the numbers of the nuclei. It reads from and writes data onto the disc. Alphabetized Parts Part numbers based on the root B, page 61 of This overview is preliminary and subject to modifications.

Safety Instructions, Warnings and Notes 2. Alignments No alignments necessary 9. To achieve this, it is important that the sledge motor can rotate as fast as possible.

Remove the four screws [3] with a Torx 6 screwdriver, and lift the DVD-M upwards datashret at the side of the disc-motor.

This modulated pattern is called a wobble groove, because the walls of the groove appear to wobble from side to side. The application can react on this with a shock recovery procedure. Processor Diagram 1 18 Servo Board Menu interface only for Digiboard Empress. Set the mains switch to the ‘on’ position keep the mains cord unplugged! Back to the Alphabetical Parts. Exploded views added in chapter 4 3. It contains logic for: Remove the three screws [1] that hold the sledge-motor assy, dataeheet lift the assy upwards.


It performs all basic servo functions: The following text will appear on the screen of the terminal program for Digiboard Empress: Command Overview We provide an overview of the nuclei and their numbers. Configuration matrix table added in chapter 2 2.

Before starting the measurement, connect the power supply to the mono board via connectorand the PC interface cable to the Service Interface connector of the ‘test recorder’. Sledge motor and hall output: This wobble provides the recorder with the timing information needed to place the data accurately on the disc. Sledge test slow In order ab5938fm let the sledge move even faster the ratio of the gearing can be reduced. Avoid direct exposure to beam. When after a while, the radial actuator drifts away, the capture point crawls a bit further on the hall sine.

Never try to align the DVD-Module!
