Mounting Direction of EMAX / EMAL Sensor to Magnetic Tape
Since the magnetic tape has two magnetized tracks, the sensor and magnetic tape must always be mounted in
the correct direction in order to obtain correct measurement results.
Marking arrows on the tape and sensor clearly indicate the correct mounting direction.
The pole finder foil, which is available as an accessory (
12.2) and is placed on the magnetic tape, can also
be used to determine the respective pole pitches. The pole pitches result in the following mounting direction:
Figure 8: Mounting direction on magnetic tape
The sensor center must be aligned to the magnetic tape center (±0.5 mm)
Markers on tape and sensor are additionally indicators for the mounting direction
When using the accessorial option FS-1000 (
12.2), the mounting direction is marked on the guide rail

Offset Calibration
After the installation of magnetic tape and measuring system (sensor head), a value is transmit via interface.
Since this value does not correspond to the machine zero point, it should be possible to store an offset on the
control side.
NOTE!
An offset is necessary in each case of a replacement of the EMAX / EMAL or magnetic tape.
