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:
The position pulse train inputs come from either of the following two terminal groups:
● PTIA_D+, PTIA_D-, PTIB_D+, PTIB_D-
● PTIA_24P, PTIA_24M, PTIB_24P, PTIB_24M
For more information about wiring, refer to Section "Control/Status interface (Page 90)" and
"PTIs (Page 100)".
