7.5 Voltage-Controlled Operation (Open-Loop U/f Control)
Overview
master
cmd. value adjustment
(depending on oper. mode)
oper. mode 2
oper. mode 1
Features
The drive function "voltage-controlled operation of asynchronous motors
without encoder in open-loop U/f control" is made available in the base
package "open-loop" in the "velocity control" mode. When the expansion
package "synchronization" has been enabled, the operating mode
"velocity synchronization with real/virtual master axis" is additionally
available.

DF000090v01_en.fh7
Open-loop U/f motor control is characterized by the following features or
core functions:
• monitoring and limitation of the maximum stator frequency change
that results from the command velocity change
