Other Key Features of the FRENIC-MEGA G2:

• It is a general-purpose inverter with best-in-class vector control, capable of vector control of both induction and synchronous motors at up to 599 Hz.
• It features dynamic torque vector control, with 200% starting torque at 0.3 Hz.
• It offers the “highest torque responsiveness to sudden load changes in its class,” minimising variations in rotational speed and suppressing vibrations.
• Precision positioning control is enabled with eight positioning data points for pulse string inputs.
• An orientation function allows machinery to be held in position via servo-locking after a stoppage.
• A PID auto-tuning function allows for quicker start-ups and simpler adjustment of proportional and integral gains.
• A load limiter improves reliability by stopping the drive when excessive torque is detected.
• Customisable logic functions with up to 260 steps eliminate the need for a PLC.
• A built-in RS-485 terminal and an RJ45 port which simplifies multi-drop connections.
• A choice of multi-function keypads with LED or LCDs is available.
• The LCD keypad features enhanced diagnostic functions, with optional memory card slots and Bluetooth support.
• Maintenance is enhanced through trace-back functions, PC and mobile loader compatibility, and easier troubleshooting.
• The drive is capable of storing alarm histories, including waveform data from before the alarms occurred.
• IP55 protection for the drive’s rear cooling system enhances cooling outside of control panels, reducing costs and saving space.
• It conforms to European safety standards – EN ISO 13849-1:2015 and IEC/EN 61800-5-2:2016 SIL3.
• The PCB coating is strengthened according to IEC 60721-3-3 class 3C2.
• The drive is globally compliant with CE, cUL, UKCA, and EAC certifications, and meets the Eco-design Directive.
