Voltage amplitude
Output voltage U of the encoder (1 V
ss
) depends on its distance from the magnetic tape. The
correlation between voltage amplitude U and encoder distance s is illustrated by Fig. 5.4, the
recommended range for the reading distance is marked in green.

Commissioning
Note:
Observe the assembly instructions of the other system components (e.g. linear motor, servo
amplifier)!
The following sequence must be observed when commissioning the distance measuring
system:
Connect encoder
Apply supply voltage (5
V)
Do not exceed the operating voltage, otherwise the encoder may be destroyed!
Check output signal e.g. with an oscilloscope
