Product Description:

The D3.F5.S1D-33EC is an axis drive module manufactured by KEB for the F5 Combivert Axis Drives series. It conditions incoming power and supplies regulated output power to synchronous motors used in industrial automation. The drive executes velocity and torque commands while protecting the connected machine, making it suitable for coordinated multi-axis motion in packaging, forming, and material-handling cells. Cabinet installation is simplified by its integrated braking element and dual encoder connections, which allow direct feedback connections within the control system.

The power stage accepts a 400 VAC/DC supply through a three-phase connection, so it can draw energy from common industrial mains or a rectified DC link. Internal IGBTs switch at a carrier frequency of 16 kHz, which reduces audible noise and improves current resolution. For transient load peaks, the overcurrent threshold is set to 150% of the rated value. The drive trips if the current rises above this threshold, protecting the power devices from excessive electrical stress. A secondary limit permits 125% short-time current, giving the motor additional torque for brief acceleration or deceleration events without exceeding its thermal capacity.

Vector regulation uses closed-loop field-oriented motor control, enabling precise speed regulation even at low shaft frequencies. Heat generated by the switching elements is removed through water cooling, allowing high continuous power density in compact enclosures. Primary position feedback is obtained from a resolver connected through a 15-pole D-Sub port. A second feedback channel receives incremental pulses from a TTL output device through a 9-pole D-Sub port. An integrated braking transistor routes excess regenerative energy to an external resistor rather than allowing it to raise the DC-bus voltage during rapid stops.
