Product Description
The Allen Bradley PowerFlex 700 drive, model 20BD040A3AYNAEC0, is an adjustable frequency AC drive offering open and closed loop torque regulation. It provides up to 5% regulation in open loop and 2% with encoder feedback, enabling full load holding at zero speed. This Frame 3 drive features I/O vector control with 24V I/O, a pre-installed brake IGBT (but no resistor), and a CE EMC compliant second environment filter. It includes a removable LCD HMI with a 7-line, 21-character backlit display, PC-based configuration support, and fault/alarm indication LEDs for optimal performance. The drive utilizes microprocessor-based inverter logic isolated from power circuits and shares a common control cassette across all ratings for simplified parts management. It's programmable for operation without a motor, incorporates an advanced thermal manager for device protection and PWM frequency reduction, and operates in 5-95% non-condensing humidity with a storage temperature range of -40 to 70C and an operating temperature range of 0 to 50C.
Is Your Device Showing These Signs?
The Allen Bradley 20BD040A3AYNAEC0 PowerFlex 755 AC drive commonly experiences issues related to IGBT failures, capacitor degradation within the DC bus, and encoder feedback malfunctions. Over time, the electrolytic capacitors degrade, leading to DC bus undervoltage faults and drive trips. Furthermore, problems arise from faulty encoder signals, causing speed regulation errors and impacting motor control performance. Addressing these issues through component replacement, firmware upgrades, and parameter adjustments restores optimal drive functionality and prevents downtime.
Technical specifications
The Allen Bradley PowerFlex 700 drive (20BD040A3AYNAEC0) is a Frame 3 AC drive with adjustable frequency and open/closed loop torque regulation (5%/2% regulation respectively). Key features include I/O vector control with 24V I/O, a pre-installed brake IGBT, a CE EMC compliant filter, a removable LCD HMI, PC-based configuration, and fault/alarm LEDs. It uses isolated microprocessor-based inverter logic, a common control cassette, and is programmable for operation without a motor. It also has advanced thermal management and operates within a specified humidity and temperature range.
