1. Discontinuation and Alternative Solutions
2. Discontinuation Information

Discontinuation Date: Production was stopped starting from October 1, 2019.

Spare Parts Support: Siemens still provides spare parts with limited inventory, but long-term maintenance depends on alternative models.

2. Modelos alternativos recomendados

SINAMICS G120 Series (Projeto Modular):

Power Matching: The G120 power module PM240-2 (FSG size) can cover the 200kW requirement, and it is matched with the control unit CU240E-2 (supports PROFIBUS DP/PROFINET).

Vantagens: Supports higher energy efficiency (such as ECO mode), integrated safety functions (STO), can be debugged through STARTER or TIA Portal, and is compatible with the parameter migration of MM440 (needs to be exported in Excel format and adjusted).

SINAMICS G120C Series (Integrated Design):

Modelo: G120C-2DP (FSG size), with a power of 200kW and built-in PROFIBUS DP.

Vantagens: High cost-effectiveness, tamanho compacto, supports the one-click cloning function (through an SD card or intelligent access module), and is suitable for replacing simple applications.

SINAMICS G120XA Series (Tipo Econômico):

Modelo: G120XA 250kW (FSG size), supports Modbus RTU/USS.

Vantagens: Optimized for the Chinese market, with a lower price, but has slightly fewer functions than G120.

3. Matters Needing Attention for Replacement

Compatibilidade de instalação: The G120 series has a smaller size (por exemplo, the size of PM240-2 FSG is 1000×305×357mm), and the cabinet layout needs to be redesigned.

Parameter Migration: Use the STARTER software to export the MM440 parameters, convert them into the G120 format and then import them. Pay attention to the differences in parameter indexes (por exemplo, P0700 of MM440 corresponds to P0700 of G120).

Protocolo de comunicação: If the original system uses PROFIBUS DP, it is necessary to configure the ProfiDrive message (such as PZD-3/3) in G120 and update the PLC configuration.

III. Application Suggestions

1. Referência de seleção

Complex Process Requirements (such as multi-motor linkage, dynamic response): Select G120 + CU250S-2 (supports encoder feedback).

Simple Replacement: Give priority to G120C-2DP, whose wiring and parameter logic are closest to those of MM440.

Cost-sensitive: Consider G120XA, but confirm whether it supports the required functions (such as PID control).

2. Debugging Tools

Basic Debugging: Use the BOP-2 operation panel or the SINAMICS intelligent access module (wireless debugging via mobile phone/PC).

Advanced Configuration: Perform parameter optimization and fault diagnosis through STARTER or TIA Portal.

3. Maintenance and Spare Parts

Spare Parts Inquiry: Visit [Siemens Industrial Mall] and enter the model 6SE6440-2UD42-0GA1 to check the inventory.

Long-term Maintenance: It is recommended to gradually replace it with the G120 series to avoid relying on discontinued spare parts.
