Product Description:
The 33.F5.A1P-90-D is a high-capacity axis inverter drive produced by KEB within the F5 Combivert Axis Drives series. It regulates motor voltage and frequency to control the starting, stopping, speed, and acceleration of machinery axes. Closed-loop operation allows the inverter to adjust its output in response to motor feedback and changing load conditions. The unit is intended for high-power motion systems that require controlled torque and precise speed regulation.
The inverter operates from a three-phase supply of 400 V AC. Its two P power modules convert the incoming electrical power into a pulse-width-modulated output for the connected motor. Under continuous duty, the power stage supplies a rated current of 800 A. This current supports up to 450 kW of shaft power when the inverter is paired with an appropriate motor. During brief periods of increased demand, the output can reach 1000 A before electronic current limiting intervenes. The carrier frequency is 2 kHz, which controls the switching pattern used to form the motor output waveform and affects audible motor noise. The electronics are installed in an IP20 housing that prevents accidental finger contact with hazardous internal components. The permissible operating temperature ranges from -10 °C to 40 °C, while the storage temperature ranges from -25 °C to 70 °C.
The integrated GTR 7 braking transistor directs regenerated energy to an external braking resistor during dynamic deceleration, eliminating the need for a separate braking transistor. Overcurrent protection activates when motor demand reaches 150% of the nominal value. A separate short-term capacity of 125% permits brief overloads without immediately interrupting operation. Compliance with EMC category C2 supports installation on industrial power networks when suitable filtering and installation practices are used. The Standard Board manages control functions and routes auxiliary status through TTL-level outputs. Incremental encoder signals enter through a Sub-D connector, enabling the controller to receive position or speed feedback from the motor system.
