Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze I5CA50030000A0000S is a dedicated frequency inverter control unit belonging to the Lenze i500 product family, specifically designed for use with i550 cabinet power units. Operating within Lenze's decoupled modular architecture, this control module separates drive control logic and processing from the power section hardware, enabling independent servicing and hardware maintenance. The unit manages motor operation across multiple control modes, including linear or square V/f characteristic control, Sensorless Vector Control (SLVC), and Sensorless Synchronous Motor Control (SL-PSM), making it suitable for dynamic speed and torque regulation in material handling, packaging, textiles, and HVAC equipment.
For system integration and parameter management, the I5CA50030000A0000S features an onboard RS-485 interface for Modbus RTU fieldbus communication operating at data rates up to 115.2 kbps, alongside physical I/O including five assignable digital inputs, one 24 V DC digital output, two configurable analog inputs, one analog output, and a changeover relay contact. Replacing an operational unit requires transferring the parameter dataset to ensure matching drive characteristics. The control unit incorporates a removable plug-in memory module (EPM) that allows zero-tool parameter transfer, enabling quick swapping of existing settings into a spare without requiring software tools. When manual parameter backup, firmware verification, or parameter extraction from a faulty board is required, expert support from ABC Industrial Parts can assist in preparing replacement hardware for immediate production use.
Diagnostic status is communicated directly via the RDY (Ready) and ERR (Error) front-panel LEDs, which indicate conditions such as missing supply voltage, drive inhibition, active warnings, running state, or output trip faults. Further detailed system analysis is accessible through an optional keypad (i5MADK0000000S) or via Lenze EASY Starter software connected using a USB module (i5MADU0000000S) or WLAN adapter (i5MADW0000000S). First-line troubleshooting for common issues involves verifying line voltage, RS-485 bus connections, parameter settings, and motor wiring. When diagnostic codes such as internal hardware failure (0x6100) or short circuits occur, internal electronics faults cannot be serviced in the field, making replacement or exchange through ABC Industrial Parts the most efficient path to restore production stability.

Programming and Configuration
The Lenze I5CA50030000A0000S control unit utilizes Lenze EASY Starter engineering software for drive parameterization, commissioning, and detailed diagnostics. Parameter datasets dictate drive functions, motor characteristics, I/O assignments, and fieldbus communication settings. Commissioning can be performed by connecting a PC to the control unit via an optional USB module (i5MADU0000000S) or wirelessly using a WLAN module (i5MADW0000000S). Alternatively, basic parameter changes and status checks can be carried out directly using the optional plug-in keypad (i5MADK0000000S).
Application data and drive parameters are stored on a plug-in removable memory module (EPM). This physical storage architecture allows application settings to be retained independently of the control unit board hardware. During hardware maintenance or spare unit commissioning, swapping the memory chip from the old control unit into the replacement module automatically restores the complete drive parameter set without requiring a software connection or re-commissioning tools.
Communication and System Integration
Network connectivity for the I5CA50030000A0000S is provided through an integrated RS-485 serial communication port using the Modbus RTU protocol. The interface supports data transfer rates up to 115.2 kbps, enabling direct integration into fieldbus networks without requiring external gateway modules. Through Modbus RTU, higher-level controllers can issue control commands, monitor operational parameters, adjust setpoints, and query real-time drive status.
The control unit also provides local signal interfaces to interface directly with external sensors, switches, and supervisory hardware. Onboard connectivity includes five digital inputs, one 24 V DC digital output rated for up to 50 mA, two configurable analog inputs, one analog output, and a changeover relay contact rated at 250 V AC / 3 A or 30 V DC / 3 A. Network diagnostics and status monitoring can be conducted over Modbus diagnostic registers or via fieldbus monitoring tools in EASY Starter.
Diagnostics and Status Indication
Real-time diagnostic states are displayed on the front face of the I5CA50030000A0000S via two primary LED indicators labeled RDY (Ready) and ERR (Error). The multi-state RDY LED signals supply voltage presence, drive inhibition, active output operation, or warning conditions. The ERR LED provides instant notification of fault conditions, turning solid red when an operational fault disables the drive output.
Comprehensive diagnostic routines can be conducted by connecting the unit to Lenze EASY Starter software, which provides access to a detailed internal diagnostic logbook. Operational parameters, fault logs, and real-time register states are also accessible through the optional plug-in keypad (i5MADK0000000S) or via Modbus RTU diagnostic registers across the fieldbus network.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| RDY (Ready) | Multi-state | Off: Supply voltage missing. Blinking slow (1 Hz): Inverter ready / inhibited. On steady: Inverter enabled and running. Blinking fast (4 Hz): Warning or error state active. |
| ERR (Error) | Multi-state | Off: Normal operation / no error active. Blinking: Warning active. On steady: Fault active, drive output disabled. |
Replacement and Spare Part Considerations
The modular structure of the Lenze i500 series decouples the I5CA50030000A0000S control unit from the underlying power section. When servicing a machine, technicians can replace the control unit without demounting the cabinet power hardware or disconnecting main supply wiring. Compatibility is maintained across Lenze i550 cabinet power units.
To avoid re-commissioning delays, the parameter dataset stored on the plug-in memory module must be inserted into the replacement control unit prior to powering on. If the memory module is missing, unreadable, or throwing error 0x6280, parameters must be loaded into the unit using EASY Starter via USB (i5MADU0000000S), WLAN (i5MADW0000000S), or keypad (i5MADK0000000S). Ensure all RS-485 Modbus RTU termination resistors and communication addresses are verified before restoring fieldbus control.
