Detailed Description 07.M4.C2D-3420 belongs to KEB classic COMBIVERT M4 inverter family. It adopts compact metal housing for cabinet DIN-rail mounting. Input voltage three-phase AC305~500V, rated output current 2.8A, apparent power 1.8kVA. It supports V/F control and sensorless vector control, delivering stable torque output for asynchronous motors. It is equipped with digital I/O terminals, analog input and analog output for speed setpoint and status feedback. The built-in brake chopper interface can connect external braking resistor for fast stop applications.

This drive can be configured via KEB operator panel or KEB software for parameter setup, fault diagnosis and motor auto-tuning. It supports RS485 serial communication for connection to PLC and upper control system. PWM carrier frequency is adjustable to reduce motor acoustic noise. It has flying restart function to catch spinning motor after brief power interruption.

Full protection functions include overcurrent, overload, overvoltage, undervoltage, drive overtemperature, ground fault, motor stall and short-circuit protection. IP20 protection grade, operating temperature range 0~50℃.

07.M4.C2D-3420 is discontinued legacy KEB drive spare part. Many old production machines still run COMBIVERT M4 drive systems. When the original drive fails, replacing it with identical 07.M4.C2D-3420 can reuse existing motor, power cable, control wiring and original parameter settings. Technicians complete wiring, parameter restore and JOG test, so the machine speed control system resumes operation and reduces downtime.

Before shipment, every 07.M4.C2D-3420 undergoes comprehensive functional inspection including power-on self-test, I/O signal test, output waveform test, serial communication verification and protection function simulation. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, parameter backup, motor tuning and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, 07.M4.C2D-3420 is reliable spare inverter for legacy KEB COMBIVERT M4 automation systems. It restores motor speed regulation performance, extends service life of automation assets and avoids high-cost whole drive system renovation.
