Product Description:
The 21.F5.M3R-95MA is an axis inverter drive manufactured by KEB within the F5 Combivert Axis Drives series. It employs closed-loop, field-oriented control to regulate induction motor torque and speed, allowing precise positioning or velocity regulation in automated lines, presses, and material-handling systems. With inverter size code 21 and housing form R, the unit shares mounting dimensions with other F5 products, simplifying cabinet layouts across multiple axes. An integrated braking transistor and an EMI filter permit direct connection to line power while providing dynamic deceleration and conducted-noise suppression for industrial automation cabinets.
Its continuous output is rated at 45 kW, making it suitable for pumps and extruders driven from a single cabinet section. To deliver this power, the inverter supplies a steady phase current of 90 A, so conductor sizing and thermal management must accommodate this load. The power section accepts a 400 V three-phase AC/DC connection, eliminating the need for step-down transformers in compatible installations. Control electronics and busbars sit behind an IP20 finger-safe cover, permitting open-cabinet mounting. Pulse-width modulation supports a carrier frequency of up to 16 kHz, while the default 4 kHz setting balances switching losses and acoustic noise. Sin/cos feedback on encoder channel 1 and TTL feedback on channel 2 support dual-loop motion control.
During transient events, the drive can deliver up to 135 A RMS, while internal control algorithms permit a short surge of 180% to accelerate heavy loads without stalling. Protective circuitry trips at an overcurrent threshold of 216%, disconnecting the IGBT stage before thermal limits are reached. Compliance with EMC category C1 is achieved through the integrated filter, allowing the unit to operate in residential or light-industrial areas without additional suppression. The drive also provides a general motor output capability of 60 HP at 230 V. Its built-in braking transistor supports regenerative axes that require rapid stopping by directing excess energy to a suitable braking resistor.
