PrincipleSIEMENS PM240-2 6SL3210-1PE22-7UL0 converts three-phase AC power into DC through the internal rectifier bridge. The Power Module uses IGBT inverter circuit to turn DC voltage into adjustable frequency and adjustable voltage AC output to drive the motor. The built-in brake chopper consumes regenerative energy on the external brake resistor during fast deceleration. The module receives speed and control commands from the CU control unit via DRIVE-CLiQ. IGBT breakdown, rectifier damage or cooling fan failure will cause SIEMENS PM240-2 6SL3210-1PE22-7UL0 to report faults and stop output.

ApplicationsSIEMENS PM240-2 6SL3210-1PE22-7UL0 is widely deployed in production lines, water treatment systems, HVAC equipment, material handling machinery and general factory automation. The Power Module provides variable frequency speed regulation for asynchronous motors, cooperating with G120 control unit, operator panel and peripheral sensors to realize closed-loop speed control. SIEMENS PM240-2 6SL3210-1PE22-7UL0 is a preferred spare for SINAMICS G120 drive system maintenance and upgrade.
