6 YASKAWA TM.A1000SW.061 Output Voltage PID A1000 Custom Software Supplement
2 Output Voltage PID
2 Output Voltage PID
‹ Overview
This software provides the capability of controlling drive output voltage independent of frequency. The features of this
custom software are typically applied as part of a system that conditions line power of varying frequencies and voltages to
a specified frequency and voltage to operate connected equipment.
‹ Applicable Models
This Output Voltage PID software is available for the drive models listed in Table 1 .
Table 1 Applicable Models
‹ Basic Concepts and Principles
An independent PID controller was added, the output of which will trim the output voltage.
Trim range for the PID is +13% to -100%. Additional positive trim (voltage boost) can be added using the Output Current
and Iq Current voltage compensation functions.
