SEW MOVIDRIVE ®  Technology application frequency converter

MOVIDRIVE ®  The complete process of technology application frequency converter debugging through PROFIBUS DP-V1 fieldbus revolves around CFP21A fieldbus card (supporting addresses 1-125) MOVISUITE ®  Engineering design software and TIA Portal programming tools are developed, covering PROFIBUS network configuration, frequency converter address setting, process data configuration MOVIKIT ®  The key operations such as software module application (Velocity Drive/Positioning Drive) and equipment replacement emphasize EMC compliant wiring, diagnostic alarm function, and safety debugging specifications, which are suitable for industrial automation integration scenarios with PLCs such as SIMATIC S7.

Basic information of the document

Project Details

Applicable equipment MOVIDRIVE ®  Technology application frequency converter (MDX9 series)

Core bus PROFIBUS DP-V1 (supports periodic/non periodic communication)

Key hardware includes CFP21A fieldbus card, USM21A interface adapter, CBG21A handheld controller

Support software MOVISUITE ® (Engineering Design), TIA Portal (PLC Configuration) MOVIKIT ®  software module

Compliance standards PROFIBUS PI specification, IEC 61158 (bus cables), EMC wiring requirements

PROFIBUS network basic configuration

(1) Hardware and wiring requirements

Bus cable: shielded twisted pair (IEC 61158 type A), with a large area of grounding at both ends of the shielding layer

Bus terminal: PROFIBUS segment head and tail devices enable terminal resistors (integrated into the plug)

Address setting: Set through the DIP switch of CFP21A (1-125), default address is 4, and it needs to be restarted to take effect after modification

Wiring specifications: laid in separate trenches with power cables, with a spacing of ≥ 20cm; metal cable racks for industrial environments

(2) Equipment Description Document (GSD)

File Name: SEW_6011.gsd (Non modifiable)

Download path: SEW official website → Online Support → Data and Files → Software → Search for "GSD Files"

Function: Provide all the parameters required for frequency converter engineering design and data exchange, which is a prerequisite for PLC configuration

Core debugging process

(1) Preliminary preparation

Hardware connection: Engineering design computer → USM21A → Inverter X32 interface (9-pin D-type)

Address setting: Use the DIP switch of CFP21A to set the PROFIBUS address (1-125)

Software preparation: Install MOVISUITE ®、 TIA Portal， Download the latest GSD file

(2) PLC side configuration (TIA Portal)

Key instructions for steps and operation content

1. Create a new project and install the GSD file to import SEW_6011.gsd, ensuring version matching

2. Add PLC and set PROFIBUS interface to select SIMATIC S7, configure IP address

3. Add frequency converter device path: Other on-site devices → PROFIBUS DP → SEW-EURODRIVE → MOVI-C MOVIDRIVE

4. Allocate PROFIBUS address consistent with CFP21A set address

Add 5 configuration process data words from slot 2 onwards (5 words/8 words, up to 16 words)

Download the project to PLC, save the project, and establish the communication link

(3) Inverter side configuration (MOVISUITE) ®）

Network scanning: Select USB network type, scan and apply frequency converter devices

Device configuration: Assign device name, download MOVIKIT ®  Software modules (recommended) or manually configuring process data sources

Parameter settings: Configure the mapping between set values and actual values, save the project and download it to the frequency converter

(4) Process data validation

Method 1: MOVIKIT ®  Diagnostic Monitor

Monitoring mode: Observe the process data transmission between PLC and frequency converter (control word/status word/speed, etc.)

Control mode: Disable fieldbus data and set parameters directly through software (dangerous area needs to be locked)

Method 2: MOVISUITE ®  Process data buffer

Check the consistency between PO data (PLC set value) and PI data (actual value of frequency converter)

Key functional modules

（1）MOVIKIT ®  software module

Module Type Core Function Process Data Word Quantity Applicable Scenarios

Velocity Drive speed regulation drive, torque control 5-word ordinary speed regulation scenario

Positioning Drive 8-character high-precision positioning scene (machine tool/robot)

(2) Parameter access function module

Module Name: SEW-MOVI-CSingleParameterAccess (FB200)

Function: Read and write frequency converter parameters through non periodic communication via PROFIBUS

Supporting Protocol: Simple MOVILINK ®  Protocol（SMLP）

Example project: TIA Portal example can be downloaded from the SEW official website

Fault diagnosis and equipment replacement

(1) LED indicator diagnosis

Measures for handling the meaning of LED name status

BF (red) long on communication interruption/unrecognized baud rate check cable/PLC configuration

BF (red 2Hz flashing) not addressed by PLC/configuration error check address/GSD file

RUN (green) constantly on, bus hardware is normal, no

RUN (red 2Hz flashing) Address 0 or>125 Reset address and restart

(2) Diagnostic Alert

Enabling method: TIA Portal device view → Slot 0 → General DP parameters → Enable diagnostic alerts

Function: Report fault number/description in text form to PLC component diagnosis

Default state: Factory enabled

(3) Equipment replacement

Operation: Insert the memory module of the old device into the new device (of the same model)

Inheriting data: driver parameters MOVIKIT ®  Configuration, fieldbus settings, address information

Advantage: No need for reconfiguration, PLC automatically recognizes new equipment

Safety regulations

Network security: Restrict Ethernet/engineering interface access and comply with IT security standards

Debugging safety: Lock the hazardous area in control mode and activate existing safety devices

Wiring safety: Power cables and signal cables are laid in separate trenches, and the shielding layer is reliably grounded

Operation permission: Only trained professionals are allowed to perform software operations
