Function

The BML is a magnetically coded, non-contact, absolute
position measuring system consisting of a sensor head
and magnetic tape. The sensor head and magnetic tape
are mounted on the machine.
There are two magnetic tracks on the magnetic tape: one
with alternating north and south poles and one with the
coding of the absolute position.
The sensors in the sensor head measure the magnetic
alternating field. Moving without any contact over the
magnetic tape, they sense the magnetic poles, allowing
the controller to determine the absolute position and the
travel range.
The BML has various interfaces: absolute serial via SSI or
BiSS C and incremental (real-time capable) analog 1 Vpp
or digital A/B as per RS422. Customer data can be stored
in the sensor head via BiSS C.
Available interfaces:
– SSI
– BiSS C
– Additional analog, incremental real-time signal
– Additional digital, incremental real-time signal

The multi-color LED is located in the front on the side
opposite the plug (see Fig. 3-1).
3.3.1
During switch-on, the LED displays the following
sequence:
Red – orange – green – LED off – red – orange – green –
LED off – green (illuminated permanently).
Each color is displayed for about one second until the LED
is illuminated permanently green. This way it is possible to
assign the colors given the current lighting conditions.
If an error occurs or a warning appears, an error or
warning sequence is displayed in place of the green LED.
Please see section 8 on page 27 to determine the
meaning of the error or warning message and LED
sequence assignment. In addition, the errors or warnings
can be found in the BiSS registry address space (see
section 6.2.3 on page 19).
