2.1.1. Product description
The DR2020 drive is the new generation of digital servo drives manufatured by Moog-Casella for controlling brushless
synchronous or asynchronous motors. It's a decentralized servo drive that can be positioned directly on the machinery with a DC power
supply module.
•
The power supply of the DM2020 supplies the "power" in direct current (+ AT and -AT) to the different DR2020 through the
connection cable applied on the terminal board
•
The first two upper connectors of the power supply terminal board carry the auxiliary power 24Vdc
•
The second two connectors at the bottom carry the power /- AT (ATTENTION HIGH VOLTAGE 560VDC or higher)
•
There are two standard power supply models (those of the DM2020 multi-axis drive)
•
Each DR2020 axis module is only available in the single axis version
•
The current flows of the various DR2020 axes range from 2 Arms to 8 Continuous Arms and 4 Arms to 16 Peak Arms
•
Sizes are 4
•
The control modes are 3
