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 cam 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 cam register is also cleared.
The speed is specified in

As only 16-bit registers have previously been possible on the control side, the position value
must be calculated first. 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: 8192
