Product features

A dependable small inverter from Siemens' popular SINAMICS G120C series, the 6SL3210-1KE27-0AF1 is primarily intended for industrial drive applications. It is the preferred option for factories and workshops that require consistent motor control because it is widely used to power devices like fans, pumps, and conveyor belts.

Let's start by examining the Siemens 6SL3210-1KE27-0AF1's primary electrical parameters. Its 37 kW rated power is exactly the same as that of 37 kW industrial motors. With a frequency range of 47-63 Hz and a three-phase AC input voltage range of 380-480 V (with a ±10% margin), it can be used with the majority of industrial power systems. It has two overload modes for output current: low overload (LO) and high overload (HO). It can manage 150% of the rated current for three seconds in HO mode, which is ideal for loads that fluctuate frequently (such as conveyor belts with different weights). It is perfect for steady-load devices like fans and pumps because it can support 110% of the rated current for 57 seconds in LO mode. Additionally, the inverter's high efficiency of roughly 97% contributes to long-term electricity savings.

Another advantage of the Siemens 6SL3210-1KE27-0AF1 is its safety. Its Safe Torque Off (STO) feature, which complies with SIL3 and PLe safety standards, safely reduces the torque of the motor in an emergency, safeguarding both personnel and equipment. Additionally, it has basic protection against common problems like motor overheating, undervoltage, overcurrent, and overvoltage. Its six digital inputs (DI), two digital outputs (DO), one analog input (AI, which operates with 0-10 V or 4-20 mA signals), and one analog output (AO) are sufficient for the majority of basic control tasks.

Application scenarios

It drives big water pumps in water treatment facilities. Its PROFINET-PN interface enables workers to remotely monitor pump speed, and its high overload (HO) mode (150% current for 3 seconds) manages abrupt pressure changes. For water treatment pumps, this makes the Siemens 6SL3210-1KE27-0AF1 an excellent option.

It manages conveyor belts for goods like bottles and snacks in food and beverage factories. In an emergency, its Safe Torque Off (STO) feature (which complies with SIL3/PLe standards) rapidly stops the motor, and its IP20 rating effectively prevents dust and splashes inside control cabinets, which is crucial for the Siemens 6SL3210-1KE27-0AF1 in food processing.

It powers material mixers or exhaust fans in factories that produce building materials, such as cement or drywall plants. The Siemens 6SL3210-1KE27-0AF1 is cost-effective in this case because of its 97% efficiency, which saves electricity, and its low overload (LO) mode, which maintains power steadily for extended periods of time (110% current for 57 seconds).

FAQ

Q: What is the Siemens 6SL3210-1KE27-0AF1, and what is its primary function?

A: The Siemens 6SL3210-1KE27-0AF1 is a variable speed drive, or SINAMICS G120C frequency converter. Its primary function is to control the speed and torque of a standard three-phase asynchronous motor. Precision control of industrial machinery is made possible by varying the frequency and voltage of the power delivered to the motor. This results in improved process control and notable energy savings in applications such as conveyors, fans, and pumps.

Q: What is the main advantage of the built-in Class A EMC filter?

A: An important benefit for industrial EMC compliance is the integrated Class A EMC filter. By lowering conducted electromagnetic emissions, it enables the drive to satisfy industrial electromagnetic compatibility requirements without the need for an external filter. This simplifies installation, lowers component costs, and conserves control cabinet space.

Q: What safety features does this drive offer?

A: A built-in Safe Torque Off (STO) safety feature is included with the 6SL3210-1KE27-0AF1. By safely disabling motor torque, STO keeps the inverter from inadvertently restarting, assisting machines in meeting safety regulations and lowering the need for extra external safety components.
