The speed is output as a two's complement value with preceding sign.
Setting the direction of rotation = forward
–
Looking at the flange connection, turn the shaft clockwise:
--> positive speed output
Setting the direction of rotation = backward
–
Looking at the flange connection, turn the shaft clockwise:
--> negative speed output
If the measured speed exceeds the display range of
–32768…+32767, this results in an overflow, which is reported in the cams register via
bit 2
0
. At the time of the overflow the speed stops at the resp/- maximum
value, until the speed is once again in the display range. In this case the message in
the cams register is also cleared.
The speed is specified in

The number of revolutions is noted in the
Multi-Turn
register, and the current
Single-Turn position is noted in steps in the
Single-Turn
register. Together with the
measuring system resolution, max. number of steps per revolution according to type
plate, the actual position can then be calculated:
Position in steps = (steps per revolution * number of revolutions) + Single-Turn position
Steps per revolution:
