Easy handling, productivity and energy efficiency – Siemens offers an answer to these trends with the SINAMICS G120P series. SINAMICS G120P is an innovative and user-friendly converter series that has been specifically optimized for pump, fan and compressor applications in the industrial environment, but also for tasks in building automation.

SINAMICS G120P offers efficient drive solutions for a wide range of applications. With their easy handling, the drives support the user not only in optimizing existing frequency-controlled drives, but also in converting fixed-speed drives and in retrofitting.

The SINAMICS G120P converter series features advanced hardware and software functions that make a substantial contribution towards saving energy and thus make more careful use of our natural resources.

User-friendliness

A high degree of user-friendliness is one of the main characteristics of the SINAMICS G120P:

• Operator panel with color display and extensive diagnostics functions (IOP‑2)
• Simple application-specific commissioning wizard "on board" the IOP‑2 (Intelligent Operator Panel)
• Plain text scripts for integration in the STARTER commissioning tool for more demanding applications
• SINAMICS SD card for storing parameter settings, cloning and local commissioning

Guided operation using wizards

SINAMICS G120P offers two basic options for guided parameterization/setting in a target application:

Commissioning simple applications
using application wizards optionally available in the IOP‑2 operator panel ¹⁾

The following wizards are available:

• Basic commissioning
• Pump with/without PID control
• Fan with/without PID control
• Compressor with/without PID control
• PID setting
• Boost setting

An appropriate connection diagram for the standard wiring can be found in the documentation of the IOP‑2 operator panel.

Commissioning of more demanding applications
using plain text scripts through solution-based dialog prompting in the STARTER commissioning tool

The wizards support setpoint input for process values and setpoint exchanges using timers. They also allow easy integration of technological functions, such as cascade connection or hibernation mode. The connection diagrams for standard wiring that are required for the wizards are also supplied.

The following wizards are available:

• Fan for exhaust air with closed-loop control of pressure/air quality
• Fan for cooling tower with closed-loop control of cooling water temperature
• Fan for stairwell with closed-loop control of pressure and essential service mode
• Fan for tunnel/parking garage with closed-loop control of air quality and essential service mode
• Fan for supply air with closed-loop control of pressure/temperature/air quality/flowrate
• Pumps with closed-loop control of pressure
• Pumps with closed-loop control of level
• Pumps for cooling circuits with closed-loop control of temperature
• Compressor with closed-loop control of pressure
