Pulse train input position control (PTI)
7.3.1
Sequence of SON
When the SINAMICS V90 servo drive operates in pulse train input position control mode
(PTI), the pulse train setpoint must be send out after the RDY signal is ok.

Selecting a setpoint pulse train input channel
As mentioned before, the SINAMICS V90 servo drive supports two channels for the setpoint
pulse train input:
● 24 V single end pulse train input
● High-speed 5 V differential pulse train input (RS485)
You can select one of these two channels by setting the parameter p29014.
