Product Description:

The C2.F5.S1D-23EA is a servo axis drive manufactured by KEB for the F5 Combivert Axis Drives series. It receives low-level command signals from a motion controller and generates the regulated three-phase output needed to run a motor with precise speed and torque profiles. By combining drive control, feedback processing, and an internal braking transistor, the unit serves as a compact power interface for automated conveyors, packaging equipment, and indexing tables. A resolver connection through a 15-pin Sub-D port lets the control section track shaft position continuously so the motor can respond accurately during starts, speed changes, and stopping cycles.

The analog control channel samples incoming process values at a resolution of 12-bit, and each sample is refreshed every 1 ms to support stable loop response. When the drive generates an analog status signal, its pulse-width-modulated stage switches at 3.4 kHz, and the resulting voltage image is reconstructed with the same conversion depth for consistent signal handling. Logic terminals accept digital commands through an input network of 2.1 kΩ, which helps interface the control inputs with standard external switching devices. The reference source can supply up to +10 VDC for a potentiometer or sensor, allowing the analog circuit to provide its own excitation voltage when an external source is not used.

Power is accepted from a 230 VAC/DC mains input, with the AC supply arranged as single-phase or three-phase, and is routed through a finned heat sink that transfers switching losses to the surrounding air. The output stage includes a sinusoidal filter centered at 178 Hz to reduce carrier-related harmonics before they reach the motor, which helps smooth the current presented to the machine. For external reference loops, the analog interface can source a maximum of 4 mA. The enclosure uses housing code D, and the relay contacts are rated for 1 A at 30 VDC for low-power status or interlock signaling.
