Drive selection is performed when the DR SEL (drive select) signal corresponding to the switch setting is active. Switch 5 (five) allows to select a drive permanently and independent of the state of the DR SEL signals (only one drive). In this case, to light the green front panel LED the Unit must be additionally selected via Interface. Switch 6 (six) is used to control the condition for the spindle motor start. Depending on the switch setting, the spindle motor is started either with the first active going edge of the corresponding DR SEL signal or when DC power is provided to the drive (Power ON). Switch 7 (seven) enables the Extended Error reporting mode which can be used to receive additional error messages. For regular use of the BASF 6190 this switch must be open.

(For operation with boards up consult factory.) Screws = M3 Housing ------- The sealed module consists of an aluminium die-cast baseplate and cover. A closed loop air filtering system inside constantly cleans the air particles which may be generated by head to disk inter- ference. An absolute breather filter for pressure equalization with the ambient air pressure protects against environmental contamination. Physical Interface ------------------ The physical interface between the BASF 6190 and the controller is done via three or four connectors. One provides the control and status lines through the "A"-cable which may be daisy chained. The second one provides the read/write signals to the star connected "B"-cable. The other connectors are used to supply DC power and for optional frame grounding. Interface Connector J1, "A"-cable --------------------------------- The "A"-cable is connected to the PC-board via a 34 pin card edge connector. Recommended mating connector is AMP P/N 88 373-3, or equivalent. The "A"-cable may be daisy-chained if more than one drive is connected to the controller. The cable may be flat ribbon or twisted pair with a maximum total length of 6m (20 ft). Interface Connector J2, "B"-cable --------------------------------- The "B"-cable is connected to the PC-board via a 20 pin card edge connector. Recommended mating connector is AMP P/N 88 373-6, or equivalent. The "B"-cable must be radially connected if more than one drive is connected to the controller. The cable may be flat ribbon or twisted pair with a maximum total length of 6m (20 ft). The cable impedance should be around 105 Ohms. Power Connector J3 ------------------ The DC-power connector is a four pin connector. Recommended mating connector is AMP P/N 1-480424-0 with pins 350078-4, or equivalent. Pin 1 +12 VDC Pin 2 GND 12V Pin 3 GND 5V Pin 4 + 5 VDC Frame Ground Connector J4 ------------------------- The Module of the BASF 6190 which is always connected to DC ground may be additionally grounded via the Fast On Terminal at the Connector side of the Unit. For normal usage this grounding is not recommended, however under severe noise conditions it may be useful. Recommended mating connector for J4 is AMP P/N 62187-1 or equivalent. Interface Electronics --------------------- The interface is compatible with the Standard ST 506/412 interface, but requires some minor modification to allow selection of all 9 (nine) data heads. ********************************************************************** F E A T U R E S ********************************************************************** BASF 6190 DRIVES SPECIFICATION 80307-076 SEPTEMBER 1985 General Description ------------------- The BASF 6190 uses the industry standard interface and dimensions to ease system integration. Up to four BASF 6190 may be connected to one controller. The use of high performance thin film disks and Mini Winchester heads together with a closed-loop air filtering system guarantees a maintenance-free operation throughout the drives lifetime and results in a MTBF of 12,000 working hours. Seek Time --------- +----------------------------------+--------+ | | 6190 | +----------------------------------+--------+ |Track-to-Track msec. typ. | 6 | +----------------------------------+--------+ |Average msec. typ. | 30 | | msec. max. | 55 | +----------------------------------+--------+ |Latency msec. avg. | 8.3 | +----------------------------------+--------+ Disk Media Defects ------------------ Disk drives are allowed to have the following number of media defects when leaving the factory: Cylinder zero is delivered error free. Maximum number of defects per drive: 1 Error per Megabyte Maximum number of defects per surface: 15 Drive Mechanism --------------- A "disk pack" consisting of a hub with 5 disks is mounted on a spindle which is directly rotated at 3600 rpm by a brushless motor. The motor current is commutated by Hall Sensors and related control electronics. Brake ----- To reduce the stop time and thus protect the heads and media, a mechanical brake is provided that reduces stop time to about 13 sec and additionally provides a transport lock against carrier- induced spindle rotation. Read/Write Heads ---------------- Because of their superior performance over conventional "Winchester Heads" the "Mini Winchester" type heads are used, giving high flying stability and readback amplitude together with low sensitity to HDI's. Fault Codes 1985 ---------------- The face panel LED which is red during power Up, is turned off when the Unit gets Ready and turn to green if the Unit is Ready and selected via interface. In case of any error the LED will start flashing in a certain "Morse" sequence thus indicating the type of error (last error is shown!). This flshing sequence is repeated until the unit is powered down or is reset (only write error can be reset). If a seek error occurred, an automatic recovery routine will take place during which the drive is not SEEK COMPL (seek complete). This recovery is retried 5 time (in extended mode only 1 recovery) before an errror is reported. All errors reported in normal mode, prevent the unit from save operation, while additional errors reported in extended mode give an indication of a condition which may later on lead to failures. Therefore extended error mode should only be used for test purposes and not regular operation. Always on: Motor not started or not up to speed or first seek in progres or Write Fault (after Power Up) 0 .... D/A offset correction not possible 1 ...- Rom-test failed *2 ..-.

Target cylinder not found 15 ---- DC fail (resets automatically via a Power Up Routine) * These codes are only displayed in extended error mode ** After 5 retries in normal mode and 1 retry in extended mode Fault Codes 1983 ---------------- The Select LED is used to flash error messages, in case certain fault conditions should arise. Error codes are presented as a Morse coded sequence, which os repeated continuously, only separated by a longer pause until the error is reset by a new seek command. RED LED IS INDICATOR - ON IS SIGNAL Always on: Motor not started or not up to speed or first seek in progres .... Write Fault (is displayed 3 times) ...- No index after motor up to speed ..-. Speed not within tolerance .-.- Index too long .--. More than 1000 steps received .--- Seek time out in first seek -... DC fail -.-- Bad first seek --.- Too high positioner velocity after first landing Single Ended Signals -------------------- All control input signals and status output signals are single ended and low active (except OP CBL DET). They must meet the following electrical specifications: Active: 0.0 to 0.4 VDC I = -40 mA (max) Inactive: 2.5 to 5.25 VDC I = +250 (open)
