3. Insert disk 1 of the
Saver/Loader in the PC disk
drive.
The following ACS software tools will be added to the
ACS Tools program group.
• ACS Saver
• ACS Loader
5.2. Adjusting the Unit
The purpose of adjustment is to setup the module and to tune the control loops. The process is
carried out using ACS Adjuster.
An adjustment session consists of the following activities:
♦ 1. Establish communication with the unit.
♦ 2. Define amplifier and motor parameters for the specific motion application, set
protection parameters, and verify that the feedback subsystem is operating.
♦ 3. Tune the control loops through a series of interactive steps where the system is
excited by a signal and the response is monitored.
The order of operation is summarized in TABLE 5-4.
TABLE 5-4 Adjustment steps
Step Description
Setup
1.
Amplifier
parameters
