Product Description:

The 07.F5.S1A-2E2A is a servo axis drive produced by KEB for the F5 Combivert Axis Drives series. In an automation cell, this unit sits between the mains supply and a motor, modulating voltage and frequency so that position loops running on the machine controller achieve precise motion. The drive accepts either single-phase or three-phase supply lines, allowing builders to use one model in multiple cabinet layouts while retaining the same resolver-based feedback structure.

The control section is designed for a nominal DC bus of 325 VDC, which it derives from a nominal input of 230 VAC. Flexible wiring is possible because the power stage accepts single-phase or three-phase feeds without derating. Continuous motor current is limited to 4 A, which corresponds to a 1.6 kVA drive rating, and the inverter can modulate output frequency up to 1600 Hz for high-speed spindle work. Current is switched at 8 kHz to reduce audible motor noise while keeping semiconductor losses within the allowed thermal limit. Resolver feedback enters through a 15-pin Sub-D, and a separate 9-pin Sub-D is provided for encoder simulation so downstream controllers can read synthetic incremental signals without additional electronics.

Short bursts are handled at 8 A for quick accelerations, while an overcurrent trip activates at 9.6 A to protect both the drive and the connected windings. The aluminum heat sink may reach 82 °C before thermal limiting reduces output, and this value is monitored internally to prevent semiconductor overstress. Environmental ingress protection is rated at IP20, making the unit suitable for enclosed panels with controlled airflow. A standstill magnetizing current of 4.4 A supports holding torque when the axis is stopped, and the resolver interface continues to provide rotor position feedback during zero-speed operation.
