e.g. U422.03 = 129 [335.7]
Real master with speed-dependent deadtime compensation
<1> Typical setting values for U424 depending on the master value source:
- approx. 3 ms with external machine encoder
- approx. 6 ms with motor encoder
- approx. 10 ms if input value is coming from SIMOLINK
<2> It is recommended to use the measured actual speed if possible
(U422.03>0)
<3> You can normally set the axis cycle lengths U425.1 and U425.2 to the
same value.
