Appendix D
Creating Custom Motor Files
Appendix D
Each motor controlled by a ULTRA 100 Series drive requires a unique
parameter set. The parameter set provides the drive with information
about the motor necessary for proper commutation, precise control
and protection.
Two types of motor parameter sets can be selected for a ULTRA 100
Series drive using ULTRA Master software:
●
Standard motors parameters reside in a motor lookup table stored
in the drive. Up to 65535 motors may be stored in the drive.
●
Custom motor parameters are created off-line and downloaded to
the drive’s personality module (EEPROM). Only one custom
motor may be stored in the drive.
This appendix defines the motor parameters and explains how the
drive uses the parameters to control the motor. A step-by-step example
details how to set up a motor file for an application using the motor’s
parameters. Difficulties commonly encountered when creating custom
motor files also are explained.
Drive and Motor File
Configuration with
ULTRA Master At startup ULTRA Master examines the contents of the /MOTORDIR
subdirectory to determine the list of motors it will display. If a custom
motor file is to appear, it must be copied into the /MOTORDIR
directory before ULTRA Master is started. Each motor file is a binary
file that contains:
●
the motor parameter set,
●
a table ID number, and
● a text string.
Because they are binary files, only ULTRA Master can be used for
editing and generation (i.e., you cannot edit motor files using a text
editor.)
Note: Additional custom motors may be stored off-line as files acces-
sible via a personal computer.
Note: ULTRA Master Advanced is required to access Custom Motor fea-
tures. The Help menu in ULTRA Master explains how to access the Advanced
features.
