The 20DD077A3EYNANBSE variable frequency AC drive is engineered by Allen Bradley within the PowerFlex 700S series, designed to effectively cater to varied motor control applications. The drive is compatible with a 3-phase input voltage of 480 VAC and can handle a robust current output of 77 Amps. Its motor support allows for up to 60 HP for standard operations and 50 HP under high-load scenarios.
This drive is constructed with an integrated LCD screen and a full alphanumeric keypad, allowing for ease of use and efficient interaction with the drive's settings. It has a built-in dynamic braking system utilizing an IGBT module, although it does not have an integrated braking resistor. The control framework leverages Phase II logic architecture and offers synchronization capability using SynchLink.
With an expanded cassette slot, this model supports optional add-ons for increased functionality. The device also features safety provisions such as Safe Torque Off (STO), further securing operational practices. Additionally, it supports dual encoder inputs for enhanced feedback. However, it does not include any pre-installed communication protocol modules and does not integrate with the DriveLogix programmable controller.
The unit's construction meets the IP20 / NEMA Type 1 enclosure rating, which provides adequate protection against dust and moisture in suitable environments. Furthermore, the 20DD077A3EYNANBSE complies with CE EMC standards under Directive 89/336/EEC with a dual-stage input filter, ensuring reliable operation amid electromagnetic interference.
