Liquid-cooled version

Optimized footprint with excellent power per unit volume

and weight

• Up to a 60% smaller footprint compared to air-cooled drive

Cooling circuit cools all of the main components

• Semiconductors, DC link capacitors, symmetrizing

resistors

Parallel configuration increases capability up to 7,500 HP

(5,700 kW)

Drinking water quality is used – chemically neutral with

pollutants removed

• Derating is not required when using anti-freeze

Only a low flow rate is required

Extremely low noise with < 56 dB(A)

SINAMICS Webserver

Direct device access in your browser

Direct access to SINAMICS S120 without requiring specific software

Can be accessed in a standard PC / laptop web browser via

all Ethernet and PROFINET interfaces

• Parameter assignment

• Diagnostics, display of all faults and warnings output on the

entire drive unit, fault acknowledgement,

parameter adjustment

• Firmware and project updates

If a WLAN Router is connected, the websites can

also be viewed using other web-capable devices

such as tablets and smartphones

SINAMICS VFD jacking system

Physically compact and energy efficient design

Smooth start and stop

Optimal load sharing, max. torque at zero speed

Extensive monitoring of all phases of jacking

Increased leg handling speed during lowering

and lifting

Torque increases slowly with brake engaged

(Motors provide full holding torque before brakes

are released / engaged)

Standard off the shelf components

Control from both central and local control consoles

Data logging (Win CC supports data logging)

Safety integrated

What makes Siemens first worldwide in machine safety?

• Safe Speed Monitor (SSM)**

• Safe Operating Stop (SOS)**

• Safe Stop 2 (SS2)**

• Safe Brake Test (SBT)**

• Safely-Limited Position (SLP)**

• Safely Position (SP)**

Safety integrated means

The drive monitors autonomously or in combination with a PLC the motor and maintains a safe

process status. Safety functions integrated in the drive ensures that, in case of an emergency stop

signal, e.g. via an emergency stop switch or a bus signal, the motor is safely stopped by the drive

Safety functions integrated in SINAMICS S120

• Safe Torque Off (STO)

• Safe Stop 1 (SS1)

• Safe Brake Control (SBC)*

• Safely Limited Speed (SLS)**

• Safe Direction (SDI)**

Encoderless safety

Several safety functions are provided, for which no failsafe or several

standard encoders need be used
