Chapter 4 Parameters|
When output frequency reaches Y-connection/Δ −connection switch frequency, drive will delay
by Pr.05-30 before multi-function output terminals are active.
Y- connection switch: can be used for wide range motor
Y connection for low speed: higher torque can be used for rigid tapping
connection for high speed: higher torque can be used for high-speed drilling
