Product Description:

The H7.F5.S1H-33EE is an axis drive module produced by KEB as part of the F5 Combivert Axis Drives series. It functions as a servo controller that governs motor speed, torque, and position in automated machinery such as packaging stations and conveyor axes. By converting the plant’s three-phase mains into regulated pulse-width-modulated output, the unit supplies dynamic motion control while coordinating with feedback devices to maintain precise axis synchronization within an automation system.

The drive accepts a three-phase input of 3-Ph 400 V AC/DC and processes those line voltages through insulated-gate transistors that switch at 16 kHz to create a smooth current waveform. It has 8 digital inputs for direct wiring of limit switches or PLC status signals, while two digital outputs, two analog outputs, and two relay contacts provide command signals back to the machine. The memory includes 14 parameter groups, allowing separate operating profiles for recipe changes or different motor data. Closed-loop control relies on resolver feedback, and the incremental encoder interface can forward position data to a master controller. Cooling is handled by a special fan mounted behind the heat sink so thermal limits are maintained during continuous operation, and the H housing format supports side-by-side cabinet installation with other F5 modules.

Short bursts of torque are managed by permitting output currents up to 125% of the nominal rating, while a hardware trip disconnects the inverter at 150% to protect the semiconductors. An integrated braking transistor dissipates regenerated energy into an external resistor, allowing the axis to decelerate without overvoltage on the DC link. For position handoff to downstream devices, incremental pulses exit through an RS422-compatible line driver, and the RS422 format helps maintain signal integrity over long cable runs inside factory enclosures.
