Q How to wire for Y-Δ switch-over?
A The picture as shown for Pr05-25 in the user manual is for indication only and is not
complete. Here’s how it should be connected.
This applies also to C/CP/CFP2000.
Q What is the difference between the Traditional OV stall prevention (Pr06-02=0)
and the Smart OV stall prevention (Pr06-02=1)?
A Over Voltage stall prevention is a function commonly used in applications where the
goal is to decelerate the motor as quickly as possible without using a braking resistor.
To enable this function parameter Pr06-01 needs to be ≠0.
In traditional OV stall, during deceleration the drive will maintain the output frequency
at a constant level when VDC > Pr06-01. When VDC<Pr06-01 the drive will always
follow the same slope to decelerate (Hz/s = constant)
