6SL3320-1TG32-2AA3

What type of industrial component is this?

This is a high-power motor module designed to regulate the electrical output supplied to an industrial AC motor. It is intended for use within a compatible SINAMICS low-voltage drive configuration.

What is the module's rated power?

The type rating is 200 kW based on the rated output current, or 160 kW based on the high-overload duty rating. These values relate to a typical six-pole standard induction motor under the specified operating conditions.

What is the rated output current?

The rated output current is 215 A. The base-load current is 208 A for low-overload duty and 192 A for high-overload duty, while the maximum stated current is 312 A.

What DC-link voltage does the module require?

The specified DC-link voltage range is 675 to 1,035 V DC. Compatibility with the wider drive configuration should be checked before installation.

What power supply is required for the control electronics?

The electronics require a nominal 24 V DC supply with a tolerance of -15% to +20%. Maximum current demand is 0.90 A.

Which motor-control methods can be used?

The module is rated for servo, V/f and vector control applications. For each method, the stated output-frequency range is 0 to 550 Hz.

What is the pulse-frequency range?

The rated pulse frequency is 1.25 kHz, while the stated maximum is 7.50 kHz. Available output current and maximum output frequency can vary with the selected pulse frequency.

How is the unit cooled?

The unit uses forced-air cooling through integrated fans. Its specified cooling-air requirement is 0.36 cubic metres per second, so adequate cabinet ventilation and airflow must be included in the installation design.

What ambient temperature range is permitted during operation?

The specified operating temperature range is 0°C to 40°C. Conditions outside this range may require additional engineering assessment or power derating.

What are the module's dimensions and weight?

The chassis measures 326 mm wide, 1,533 mm high and 545 mm deep. Its net weight is approximately 136 kg, so the enclosure and mounting arrangement must accommodate both its size and mass.

What enclosure protection rating does it have?

The module has an IP20 protection rating and a chassis-style construction. It is therefore intended for installation within a suitable industrial cabinet or protected electrical area.

What power-terminal connections are provided?

The motor, DC-link, PE1 and PE2 connections each use two M10 screw connections and accept conductor cross-sections up to 2 x 240 mm². The braking-module connection uses an M6 bolt.

What is the maximum permitted motor-cable length?

The stated maximum is 300 metres for shielded cable and 450 metres for unshielded cable. These figures refer to the combined length of the motor cables and DC-link connections within the configuration.

What installation altitude is specified without derating?

Siemens 6SL3320-1TG32-2AA3 is rated for installation at altitudes up to 2,000 metres without derating. Installations above this level require consideration of reduced cooling performance and electrical clearances.

What overload capability does the module provide?

For low-overload duty, the 208 A base-load rating allows 110% for 60 seconds or 150% for 10 seconds within a 300-second cycle. For high-overload duty, the 192 A rating allows 150% for 60 seconds or 160% for 10 seconds within the same cycle.

What is the module's DC-link capacitance?

The specified DC-link capacitance is 2,800 µF. This forms part of the module's internal power-stage design and should be considered when assessing the complete DC-link configuration.

What power losses should be considered when designing the cabinet?

The stated maximum power loss is 3.09 kW at 50 Hz and 690 V, or 2.91 kW at 60 Hz and 575 V. These figures can be used when calculating cabinet ventilation and heat dissipation requirements.

How loud is the module during operation?

The specified sound-pressure level at a distance of one metre is 69 dB at 50 Hz and 73 dB at 60 Hz. Actual noise levels may vary with loading, airflow and the surrounding enclosure.
