Configuration and Operation
4.1
Variables and Commands
Drive functionality is configured using various commands and variables, which
are transmitted over the communication bus. The terms “variables” and
“parameters” are used interchangeably; “drive parameter set” refers to the set
of variables that are specifically defined for a particular application.
Commands and variables are identified by a mnemonic (VarCom) name. For
example, MPOLES is the mnemonic used to read and write the setting for the
number of motor poles.
VarCom instructions, which are used with serial communications, are detailed in
the CDHD VarCom Reference Manual.
Some variables are read-only, while others allow read/write access. Variables
can be stored in the CDHD’s non-volatile memory (flash memory) for use at each
power-up.
In general, drives are shipped from the factory with motor parameters set to
zero and application parameters set to their default values.
4.2
ServoStudio Software
ServoStudio is a graphic interface provided with the CDHD to enable setup,
configuration and tuning of the drive.
ServoStudio allows you to program the drive parameters specifically for the
motor to which the CDHD is connected, and for the particular operation that the
drive will be performing in the machine.
ServoStudio provides two primary ways for setting up the CDHD servo drive.
Using the Setup Wizard, which takes you step-by-step through the setup
and configuration process; this method is recommended for novice users.
Using each setup window individually, to access and define specific drive
functions.
The ServoStudio window has four function areas:
Toolbar
Contains quick access buttons for CONFIG (to trigger internal
drive configuration), Enable/Disable, Offline/Online and Save
(to save parameters to non-volatile memory).
