6SL3210-1RE31-1AL0

What is this module used for?

It is a SINAMICS PM240P-2 power module used as the power stage of a variable speed drive system, converting a 3-phase AC supply into a controlled 3-phase output for AC motor speed and torque control.

What supply voltage and frequency range does it accept?

It is designed for a 3-phase AC supply of 380 to 480 V (±10%) at 47 to 63 Hz.

What motor output rating can it deliver?

Typical ratings are 55 kW in Low Overload (LO) duty and 45 kW in High Overload (HO) duty. The output is 3-phase AC, with rated voltage shown as 400 V (IEC) / 480 V (NEC).

What are the rated output currents?

Rated output current is 110 A (LO) and 90 A (HO), with a maximum output current of 149 A.

What overload capability is available?

LO duty supports 110% overload for 57 s (300 s cycle) and 135% overload for 3 s (300 s cycle). HO duty supports 150% overload for 60 s (300 s cycle).

What control modes and output frequency ranges are supported?

The output frequency range is 0 to 200 Hz for vector control and 0 to 550 Hz for V/f control.

What is the pulse frequency?

The pulse frequency is 4 kHz.

Does it include an integrated EMC filter?

Yes. It features an integrated filter class listed as Class A.

What cooling method does it use and what airflow is required?

Cooling is internal air cooling. The specified cooling air requirement is 0.083 m³/s.

What ambient conditions is it designed to operate in?

Operating temperature is -20 to 40 °C in LO duty and -20 to 50 °C in HO duty. Relative humidity is up to 95% RH (non-condensing). Installation altitude is specified up to 1,000 m.

What ingress protection rating does it have?

It is rated IP20 (UL open type), intended for installation inside an enclosure or panel.

What are the mechanical dimensions and approximate weight?

Approximate dimensions are 275 mm (W) x 551 mm (H) x 237 mm (D), with a net weight of about 28 kg.

What cable lengths are supported for the motor connection?

Maximum motor cable length is specified as up to 200 m with shielded cable and up to 300 m with unshielded cable.

What connection type and conductor sizes are used for the power terminals?

Both line-side and motor-side connections are screw-type terminals. The specified conductor cross-section range is 25 to 70 mm² (approximately AWG 4 to AWG 1/0).

Which duty rating should be chosen for typical applications?

LO duty is generally suited to steady-load applications where only modest overload is required (higher continuous kW rating), while HO duty is intended for applications needing higher short-term overload (lower continuous kW rating). For reference, this module’s datasheet lists 55 kW (LO) and 45 kW (HO) for 6SL3210-1RE31-1AL0.
