EN921 - Variable Voltage w/ PI Power/Current Control

Description

Custom Firmware EN921 differs from the standard 1336 PLUS

II

version

3.002 firmware as follows:

• Drive parameters have been added to allow the drive output voltage to be

controlled independently of the commanded output frequency. All
voltage parameters are accessed from the new “Voltage Control”
parameter group following the “Motor Control” group.

• A new “Voltage PI” (proportional-integral) parameter group has been

added to allow the dynamic adjustment of output voltage from a
reference and feedback signal error calculation. All “Process PI
functionality (PI regulation of output frequency) available in the standard
firmware has been removed in this custom firmware.

!

ATTENTION: This Custom Firmware has been designed for a
specific application and differs from the standard 1336 PLUS

II

product offering. It must be installed and run only under this
custom application. Attempting to run this Custom Firmware
under any other type of application or condition could result in
unpredictable and/or hazardous conditions.

Voltage
Control

This group of parameters are used to independently control drive output voltage.

[Control Select]

Selects the motor control method for the drive. The default
setting provides full stator flux control that is suitable for
most applications.
