Product Description:
The C1.F5.S1D-23EA belongs to the F5 Combivert Axis Drives series produced by KEB. It is an AC drive that performs closed-loop, field-oriented control of synchronous or induction motors, making it suitable for coordinated axis tasks in automated machinery. By integrating a braking transistor and multiple analog and digital interfaces in a compact Type D housing, the unit provides the command processing and power dissipation needed for precise speed and torque regulation in conveyors, packaging lines, and similar motion systems.
Two differential analog inputs are sampled at a 12-bit depth with a scan time of 1 ms, giving the controller fine voltage resolution for torque or speed setpoints. The analog output stage supplies up to 5 mA and modulates its signal with a carrier frequency of 3.4 kHz for drive status feedback to external PLC equipment. Digital control lines have an input resistance of 2.1 kΩ, limiting sink current from sensor blocks and contact closures. A separate reference output delivers 4 mA for potentiometer excitation, while the 24 V logic rail can supply up to 100 mA to field devices. Feedback connections include a 9-pin D-sub connector for encoder simulation and a 15-pin D-sub resolver port, allowing the drive to emulate or read position transducers without additional converters.
The power section incorporates an internal braking transistor, so no external chopper module is required when dynamic deceleration energy must be routed to a resistor bank with a braking resistance of 100 Ω. The enclosure provides IP20 protection against finger contact and supports continuous operation with a heat sink temperature up to 90 °C. The drive can be installed at sites up to 2000 m above sea level. Its enclosure is intended for installation inside a suitable control cabinet, where the surrounding structure can provide additional protection from contaminants and accidental contact. The integrated interfaces reduce the need for separate signal converters, while the braking transistor provides a direct path for managing regenerated energy during deceleration.
