Sample wiring for vector V/f drives

The following diagram shows the maximum number of controllable vector V/f drives with
additional components. The sampling times of individual system components are:
● Active Line Module: p0115[0] = 250 µs
● Motor Modules: p0115[0] = 125 µs
● Terminal Module/Terminal Board p4099 = 1 ms
● Max. 12 axes can be controlled in V/f mode

Notes on the number of controllable drives

The number and type of controlled axes and the extra activated functions of the project can
be scaled by configuring the firmware. Especially for demanding configurations, drives with
high dynamics or a large number of axes with additional utilization of special functions for
example, a check using the SIZER configuration tool is recommended. The SIZER
calculates the feasibility of the project.
The maximum possible functionality depends on the performance of the Control Unit used
and the components configured.
