Observe the correct sequence to servo-on the converter smoothly.
Description of function
When the converter operates in the fast pulse train input position control mode (Fast PTI), the
pulse train setpoint must be sent out after the RDY signal is at high level.

9.5.2 Selecting a setpoint pulse train input channel
Overview
The conv
erter supports two channels for the setpoint pulse train input:
• 24V single end pulse train input
• High-speed 5V di󹪜erential pulse train input (RS485)
Description of function
You can select one of the two channels. The position pulse train inputs come from either of the
following two terminal groups.
