Product Description:
The 21.F5.M3R-96MA is an AC inverter drive manufactured by KEB within the F5 Combivert Axis Drives series. It sits between a three-phase supply and a motor, shaping voltage and frequency for precise speed, torque, and braking control in automated machinery. Form-factor code R and the included filter package support direct cabinet mounting for demanding axis applications inside compact cabinets.
The drive accepts a 3-Ph 400 V AC input supply, and its rectifier links all three phases for balanced loading. The output bridge delivers 90 A continuously, which is sufficient for motors rated at 60 HP. Dynamic stopping is handled by the GTR7 braking transistor working with an installed resistor and the integrated EMI filter. Position feedback enters through a D-Sub 15-pole connector that carries SIN/COS signals to the control board.
During acceleration, the drive can momentarily furnish 135 A, and the 150% peak-current factor reflects that short-term overload capability. An over-current trip set at 180 percent helps protect the power stage during abnormal load events. Switching at 8 kHz reduces audible noise while keeping losses within standard cooling limits, so no auxiliary fan is required. A D-Sub 9-pole pass-through also regenerates the encoder stream as a TTL output for downstream controllers.
