Product Description:

The 12.F5.A1D-YLP0 is an inverter module in the F5 Combivert Axis Drives series from KEB. It is intended to regulate squirrel-cage or permanent-magnet elevator motors, providing closed-loop speed and torque control so cars start, travel, and stop smoothly under varying load conditions. By integrating into a machine room or cabinet with other lift components, the drive delivers the commanded motion profiles while applying the protective functions expected in modern conveyance systems.

For line power, the unit accepts a three-phase input of 400 V AC or a comparable rectified DC bus, eliminating the need for an external transformer in most European lift installations. An inverter size code of 12 indicates the frame dimensions and semiconductor capacity required to energize motors up to 5 HP. The housing carries an IP20 rating, so it must be mounted inside a clean electrical enclosure that prevents accidental contact with live parts. Safe continuous operation is specified for ambient temperatures from -10 to 45 °C. Within this range, the internal thermal model maintains the overload curves and keeps the IGBTs within rated junction limits. The control stage uses the Application configuration, which supports user-programmed sequences that match the acceleration, deceleration, and leveling requirements of lift service.

A factory-installed Standard Board handles digital and analog I/O, while a discrete braking transistor provides dynamic energy dissipation during rapid car deceleration or counterweight imbalance. Encoder feedback is optional, and the base unit is supplied without factory-installed encoder feedback. This leaves the feedback interface open for a matching incremental or absolute encoder option. Standard forced-air cooling channels move heat away from the power stack, and when the system is idle, the electronics can be stored safely from -25 to 70 °C without damage to capacitors or protective coatings.
