Product Description:

The 07.F5.A1D-3BHA is an axis inverter drive manufactured by KEB, and it belongs to the F5 Combivert Axis Drives series. Within an automation cell, this drive converts the fixed mains supply into a variable-frequency, variable-voltage output that lets synchronous or asynchronous servo motors follow precise speed, torque, or position commands. By integrating the control logic and power stage into one enclosure, it reduces panel depth and provides a common platform for coordinated motion on packaging, printing, and material-handling machinery. The device also offers fieldbus signal connections through its standard interface.

Signal conditioning on the standard board starts with the analog inputs; their high impedance of 55 kΩ minimizes loading on external transducers, while a 12-bit converter delivers 4096 command steps for fine speed scaling. A three-phase supply of 400 V AC/DC feeds the bus, which is pulse-width modulated at a rated carrier of 16 kHz to keep motor noise low. Analog outputs feature 10-bit resolution, a 100 Ω source resistance, and switch at 3.4 kHz for feedback to PLCs. Digital inputs use 2.1 kΩ pull-ups, and the drive accepts feedback through the resolver + incremental input interface. The incremental channel supports up to 300 kHz with a 150 Ω termination. Reference outputs of +10 VDC and 4 mA support potentiometers or loop isolators.

For short acceleration bursts, the inverter can supply a peak of 180 % of its nominal current, while an overcurrent trip activates at 216 % to safeguard the IGBTs. The integrated braking transistor diverts regenerated energy into an external resistor, preventing DC bus overvoltage during rapid deceleration. Two transistor-driven digital outputs share a budget of 50 mA DC, allowing status relays or indicator lamps to be driven directly.
