GE A20B-0004-0170/10D Servo Drive

The GE A20B-0004-0170/10D regulates speed and position for CNC servo motors. This servo drive measures 300 mm in height and 180 mm in width. It has a depth of 160 mm, so it fits standard CNC cabinets easily. The unit weighs 5.6 kg, making mounting secure and stable.

Internal Power Stage and Component Layout

This servo drive contains six IGBT modules arranged on its main power board. Each IGBT handles up to 30 amps of continuous current without overheating. The GE A20B-0004-0170/10D includes a separate gate driver board for switching control. Three Hall effect sensors monitor phase currents in real time for accurate regulation. The drive stores 2400 µF of capacitance on its DC link bus.

Input Power and Output Specifications

You must supply 230V AC three-phase power to the main input terminals. The drive accepts a voltage tolerance of ±10 percent from this nominal value. The GE A20B-0004-0170/10D delivers 5.5 kVA of continuous output power. It provides 15 amps of continuous current to the connected motor. For peak loads, the unit supplies 30 amps for up to 3 seconds.

Control Interfaces and Feedback Connections

You will find one resolver interface port on the front panel of this drive. This port accepts feedback signals from a resolver transducer on the motor. The GE A20B-0004-0170/10D also provides three digital input channels for enable and reset. Two relay outputs indicate drive status as ready or faulted clearly. A 9-pin D-sub connector handles analog command signals of ±10V DC.

Energy Storage and Regenerative Management

The DC link capacitance of 2400 µF absorbs regenerative energy from decelerating motors. This storage reduces voltage spikes on the internal DC bus significantly. The GE A20B-0004-0170/10D also includes a braking chopper for excess energy dissipation. An external braking resistor connects to the dedicated terminals for heavy loads. The drive stores no backup battery for parameters, so you should save settings externally.
