You can configure the operation mode (PT Mode) of the drive and select the
Command Source for the Master input in KNX5100C software.
The PTO inputs of the Kinetix 300 or the Kinetix 5100 servo drives can be
differential or single ended. Differential inputs are preferred.
The Kinetix 5100 drive also provides the ability to filter pulse input and to
reject high-frequency noise. Using a filter width that is four times smaller than
the actual pulse width is recommended. The supported filter widths are shown
in Table 56
.
