6SL3544-0TB02-1MA0

What is this unit used for?

This item is a control unit for the Siemens SINAMICS G110M drive system. It is intended for decentralized motor control arrangements where a compact drive package is needed near the machine, such as conveyors, material handling equipment, and similar industrial applications.

Is this a complete drive or a control unit only?

It is a control unit only, not a complete standalone drive. It is typically used as part of a SINAMICS G110M assembly and should be matched with a compatible G110M power module for the correct frame size and connection style.

What communication concept is this version designed for?

This version is described as an AS-i control unit within the SINAMICS G110M range. The 6SL3544-0TB02-1MA0 is the FS71 connector-based variant with Han-Q style connection format.

What enclosure rating does it have?

The datasheet lists this control unit with an IP65 degree of protection, making it suitable for industrial environments where a sealed decentralized drive arrangement is required.

What power supply does it require?

The listed external supply requirement is 20 to 28 V DC. Maximum power consumption is stated as 0.29 A, so the available control supply should be sized accordingly.

What control methods are listed for this unit?

The published data includes V/f linear, square-law, and parameterizable control, V/f ECO linear and square-law operation, sensorless vector control, vector control with sensor, encoderless torque control, and torque control with encoder. This gives flexibility for a range of motor control strategies within the G110M platform.

What input and output arrangements are listed?

The datasheet shows four standard digital inputs, one fail-safe digital input implemented using two standard digital inputs, two digital outputs as relay changeover contacts, and no analog/digital inputs.

What are the physical dimensions and weight?

The listed dimensions are 216.0 mm height, 171.0 mm depth, and 105.0 mm width. Net weight is stated as 1.85 kg.

What connection details should be checked before installation?

Key connection points to review include screw-type terminals on the line side, a Han Q4/2 connector at the motor end, conductor cross-sections of 1.00 to 2.50 mm² (18 to 14 AWG), and PE connection on the housing using an M5 screw.

What motor cable length is listed?

The datasheet states a maximum shielded motor cable length of 5 m. This is an important installation detail when planning the position of the drive and motor.

What ambient conditions are listed for operation and storage?

The stated operating temperature range is -10 to 55°C, with storage from -40 to 70°C. Relative humidity is listed up to 95% RH, with condensation not permitted.
