Product Description:

The 12.F5.M1D-1A4A is an axis drive module produced by KEB for the F5 Combivert Axis Drives series. It modulates power between a three-phase supply and a synchronous or induction motor. This allows speed, torque, and position to be adjusted in automated machinery lines. The module serves as the power stage for a controlled axis where stable motor response is required during changing load conditions. It is suitable for machine functions that depend on repeatable acceleration and deceleration during normal production cycles.

This model can deliver up to 5 HP of motor output when paired with a compatible motor. It operates from a 3-phase 230 V AC/DC bus, and its inverter section supplies a continuous phase current of 16.5 A under nominal load; short acceleration periods can raise demand to 29.7 A. The pulse-width modulation stage runs at a rated switching frequency of 8 kHz, and it can be increased to 16 kHz when finer current resolution is needed and the available thermal margin permits it. The higher switching setting can also help smooth current control in applications that need refined motor behavior. A built-in braking transistor directs regenerated energy to an external resistor during rapid deceleration, and inverter size code 12 identifies the mechanical outline used in cabinet layouts.

The housing has an IP20 enclosure rating, so the drive must be installed in a closed electrical cabinet where accidental contact is limited and liquids are kept away. Continuous operation is permitted in ambient temperatures from -10 to 45 °C, and storage is permitted from -25 to 70 °C when the unit is not operating. Two feedback interfaces are provided: a 15-pole D-Sub for TTL incremental encoders and a 9-pole D-Sub for SSI absolute encoders. The separate encoder inputs allow the module to work with either incremental feedback for speed and position tracking or SSI feedback where absolute position data is preferred. This gives the axis flexibility for positioning tasks without requiring a different drive module.
