The velocity is output as a two's complement value with preceding sign.
Rotational direction setting = forward
Looking at the flange connection, turn the shaft clockwise:
--> positive velocity output
Rotational direction setting = backward
Looking at the flange connection, turn the shaft clockwise:
--> negative velocity output
If the measured velocity exceeds the display range of
–32768…+32767, there will be an overflow that is reported in the cam register via bit 2
0
.
At the time of overflow, the velocity stops at the respective +/- maximum value until the
velocity has returned to within the display range. In this case, the message in the cam
register is cleared as well.
The velocity is specified in Increments per Integration time standard.
