The BASF 6190 has 7 (seven) switches to select different options:
Four switches (1 - 4) are used to set the drive address. 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.
Signal Active when Switch is closed.

The BASF 6190 may be operated in any orientation. (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.

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.

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 ..-. No index in first seek
3 ..-- Spindle spin error
4 .-.. No good first seek
5 .-.- Reserved
**6 .--. CYL 500 not found in first seek
7 .--- Velocity offset to high
8 -... Spindle did not rotate
9 -..- Velocity to high in first seek
**10 -.-. CYL 500 not found in recovery
**11 -.-- Recovery failed
12 --.. Ontrack offset too high after averaging
*13 --.- Inconsistent servo pattern found
14 ---. 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)
