Product Description:

The 07.S4.D30-347E is a servo controller manufactured by KEB and assigned to the S4 Combivert Servo Controllers series. This unit converts fixed three-phase line power into regulated pulse-width-modulated output for synchronous or induction servo motors, allowing tight position, speed, and torque control in automated assembly cells, conveyors, and precision packaging stations. Because the output is regulated electronically, the controller can support repeatable changes in motor speed and torque during indexing, transfer, and positioning cycles. It is intended for cabinet-mounted motion systems where stable motor response and compact installation are both important.

The controller operates on a 400 V AC voltage class and draws a rated input current of 3 A. It supplies a continuous and stall current of 2.7 A, and for brief acceleration demands it can deliver a peak current of 10.6 A for 200 ms. Protection is rated IP20, so the unit is meant for installation inside a closed electrical cabinet. Above 1000 m, output must be reduced by 1 percent per 100 m, the line fuse should not exceed 10 A, and terminal wiring must use conductors of at least 1.5 mm². These electrical limits should be matched with the incoming supply and cable sizing so the drive remains within its allowed operating range.

This drive may be mounted up to 2000 m above sea level and in spaces where relative humidity does not exceed 95% without condensation. The humidity limit assumes a dry cabinet interior, helping prevent moisture from collecting on live parts or reducing insulation performance. The housing has a width of 90 mm, a depth of 160 mm, and a height of 250 mm, which helps conserve panel area in stacked layouts. An enclosure weight of 2.0 kg reduces handling load during installation and supports compact cabinet arrangements. The depth and height should be considered when planning internal cabinet clearance and airflow.
