Detailed Description – Siemens SIMOCODE pro 3UF7 Motor Management Basic Unit

1. Series Overview – Intelligent Motor Management

The SIMOCODE pro 3UF7 is a modular, flexible motor management system. It controls and protects constant-speed motors in low-voltage applications. The Basic Unit serves as the central component of every SIMOCODE pro system. Therefore, it provides the core intelligence for motor protection, control, and diagnostics.

Each SIMOCODE pro system comprises a Basic Unit and a separate Current Measuring Module for each feeder. These modules connect electrically via a system interface cable. In addition, they can mount mechanically connected or separately (side by side). An Operator Panel is optionally connected for control cabinet door mounting.

2. Basic Unit Variants

SIMOCODE pro offers two device series with different functional scopes.

Basic Unit 1 (SIMOCODE pro C) – The compact, cost-effective solution for standard motor protection and direct/reversing starter control.

Basic Unit 2 (SIMOCODE pro S / pro V) – The variable system offering numerous additional functions. For example, it supports star-delta starters, two-speed motors, solenoid valve actuation, positioner actuation, and soft starter actuation. Moreover, Basic Unit 2 can expand with digital, analog, temperature, ground-fault, and fail-safe expansion modules.

3. Integrated Protection Functions

The Basic Unit executes all motor protection and control functions autonomously, even when communication to the automation system is interrupted. As a result, this ensures full feeder functionality or parameterized safe behavior during bus failure.

Protection Functions:

• ✓ Electronic overload protection – Inverse-time delayed, CLASS 5 to 40 adjustable

• ✓ PTC thermistor protection – Binary thermistor input for motor winding monitoring

• ✓ Phase failure / imbalance protection – Detects missing or unbalanced phases

• ✓ Motor stall protection – Detects blocked rotor conditions

• ✓ Current limit monitoring – User-configurable thresholds

• ✓ Voltage and power monitoring – With current/voltage measuring module

• ✓ Ground fault monitoring – Via current measuring module or external summation transformer

• ✓ Temperature monitoring – Via optional temperature module (PT100/PT1000, KTY83/KTY84, NTC)

4. Predefined Control Functions

Numerous pre-defined motor control functions are integrated into the Basic Unit. These include all necessary logic operations and interlocking functions. Furthermore, users can freely assign these functions to the device inputs and outputs (including the PROFIBUS/PROFINET process image).

Available Control Functions:

• ✓ Direct-on-line (DOL) starter

• ✓ Reversing starter

• ✓ Star-delta starter (also with direction reversal)

• ✓ Two-speed motors with separate windings

• ✓ Two-speed motors with Dahlander windings

• ✓ Solenoid valve actuation

• ✓ Positioner actuation

• ✓ Soft starter actuation

5. Communication Options

SIMOCODE pro Basic Units offer different communication interfaces depending on the model.

Important: One Basic Unit supports only one communication protocol. Therefore, you must select the protocol at the time of ordering.
