Siemens PM240 SINAMICS G120 standard inverter

Siemens PM240 is a power module in the SINAMICS G120 series inverter. The following is a detailed introduction:

Overview

The PM240 power module has a power supply voltage of three-phase 380V to 500V and a power output range of 0.37kW to 132kW. It adopts a modular structure design and has a variety of new functions, setting new standards for general-purpose inverters in terms of safety and communication capabilities.

Features

Rich control types: Supports multiple control types such as V/F, FCC, VC, SLVC, etc. to meet different application requirements.

Hot-swap function: Module replacement can be performed while the system is running, that is, hot-swap, which is convenient for maintenance and upgrading and reduces downtime.

Safety function: It has functions such as safe torque off (STO), safe stop 2 (SS2), safe limited speed (SLS) and safe brake control (SBC), which complies with EN 954-1 Category 3 and IEC 61508 SIL2 standards to ensure the safety of personnel and equipment.

Integrated brake module: The brake chopper is integrated inside. When the inverter is running in regenerative mode (for example, when braking a mass with a large moment of inertia), the brake resistor can be used to consume the excess energy of the DC bus and convert it into heat energy.

Technical parameters

Overload capacity: The high overload module can last for 3s at 160% load, 57s at 136% load, and 240s at 100% load; the light overload module can last for 3s at 150% load, 57s at 110% load, and 240s at 100% load.

Protection level: IP20, suitable for ordinary industrial environments.

Dimensions: Different power levels correspond to different frame sizes. For example, the size of the 18.5kW module is 275mm wide × 204mm deep × 512mm high (excluding the control unit).

Applications

PM240 power modules can be widely used in various industrial fields, such as pumps, fans, compressors, conveyors, mixers, agitators, etc. They can also be used in continuous processes with high speed and torque accuracy requirements, as well as single-axis or multi-axis coordinated positioning applications.
