Function
An angle change at input CONVPHPHD1−IN is converted into a speed.
l The speed at the output CONVPHPHD1−OUT can be adapted by means of a division ratio.
The numerator (C1452) and denominator (C1453) can be set between −32767 and +32767.
l The output is limited to
±n = 30000 rpm.
l CONVPHPHD1−FAIL = HIGH for the time of limitation.
Note!
Angle errors can occur in the following function blocks if the output is limited. The profile position can
thus be lost.
