Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E93DA552I4B531 REGULATOR is an integrated 9300 Servo PLC drive controller designed for high-dynamic motion control and decentralized automation. Operating across a 3-phase AC supply voltage range of 320 V AC to 528 V AC, this 5.5 kW servo controller delivers a continuous output current of 13 A at an 8 kHz switching frequency, with a peak output capacity of 19.5 A to handle demanding acceleration phases. By integrating an IEC 61131-3 compliant soft PLC directly into the drive hardware, the unit executes local motion sequences such as electronic gearing, cam profiles, and multi-axis positioning without overburdening centralized machine controllers.
For system integration and commissioning, the E93DA552I4B531 features dedicated Sub-D connectors for resolver feedback on X7 and incremental or SinCos encoder feedback on X8, alongside 8 digital inputs, 4 digital outputs, 2 differential analog inputs, and 2 analog outputs. Real-time network integration is enabled through an integrated CANopen system bus interface and an Automation Interface (AIF) expansion slot, which accepts optional communication modules such as PROFIBUS-DP or EtherCAT. Preparing a replacement spare unit requires transferring parameter sets and PLC programs using Global Drive Control (GDC) software version 4.x or higher, Drive PLC Developer Studio (DDS) version 2.x or higher, or by cloning data directly using the removable E93DZM memory module. Technical assistance with parameter transfer or software alignment is available through ABC Industrial Parts.
Diagnostic feedback is provided on the front panel via tri-color LED indicators, including a Ready LED, Error LED, and CAN system bus LED. System state monitoring and fault analysis are further supported by a TRIP memory log accessible via an optional EMF2102IB keypad or GDC software. Active fault codes indicate specific issues such as overcurrent (OC1, OC2, OC5), DC bus overvoltage or undervoltage (OU, LU), supply phase failure (LP1), heatsink or motor thermal faults (OH, OH4), feedback signal errors on X7 or X8 (Sd2, Sd3), and communication timeouts (CE0, CE1). When internal hardware faults like EE or H05 occur, field repair is not possible, and exchanging the module or using a fully tested replacement unit from ABC Industrial Parts offers the quickest path back to full production.

Programming and Configuration
The Lenze E93DA552I4B531 incorporates an IEC 61131-3 soft PLC directly into the drive hardware, enabling local execution of complex logic and motion control routines. Engineering and program development are performed using Drive PLC Developer Studio (DDS) version 2.x or higher, which supports standardized PLC programming languages and cyclic task configuration. System parameterization, drive commissioning, and variable tuning are managed via Global Drive Control (GDC) software version 4.x or higher.
To simplify field replacement and minimize downtime, the drive regulator utilizes a removable E93DZM memory module. This module stores complete drive parameters and compiled IEC 61131-3 user programs, allowing direct parameter and program cloning between units without requiring a PC connection. When transferring projects electronically, developers must ensure that PLC cyclic task execution limits are monitored to prevent task watchdog faults.
Communication and System Integration
Communication and system coordination across multi-axis machine setups are handled via the onboard CANopen system bus interface connected at interface X4. The CANopen link supports high-speed parameter exchange, cross-axis synchronization, electronic gearing, and cam profile processing across drive modules. Direct connectivity to engineering PCs or diagnostic software can be established using the optional EMF2177IB PC USB/CAN adapter.
The onboard Automation Interface (AIF) expansion slot provides modular flexibility for fieldbus networks. By installing option modules such as the EMF2131IB or EMF2133IB PROFIBUS-DP modules or the EMF2192IB EtherCAT module, the servo controller integrates into centralized control networks. Physical connection points include Sub-D terminal connectors for resolver feedback (X7) and encoder feedback (X8), as well as dedicated I/O terminals providing 8 digital inputs, 4 digital outputs, 2 differential analog inputs, and 2 analog outputs.
Diagnostics and Status Indication
The E93DA552I4B531 includes built-in diagnostic status LEDs and automated TRIP fault logging. Operators can view active fault history and drive status using the plug-in EMF2102IB XT Keypad or by connecting Global Drive Control (GDC) software via the CAN system bus interface or AIF slot. Real-time status registers are accessible continuously across the system bus for control system integration.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready | Green - Solid / Flashing | Continuous: drive controller operational and ready. Flashing: drive inhibit active or initialization in progress. |
| Error | Red - Solid / Flashing | Continuous: active TRIP fault present. Flashing: active warning message. |
| CAN | Green/Red - Solid / Red | Green: CAN system bus running normally. Red: bus off or communication error. |
Replacement and Spare Part Considerations
When replacing a Lenze E93DA552I4B531 drive regulator, verify that the exact part number matches the target installation. The unit operates on a 3-phase AC supply voltage of 320 V AC to 528 V AC and delivers 13 A continuous output current (5.5 kW rated power). A replacement unit must be configured with the identical parameter set and IEC 61131-3 soft PLC program as the original unit before putting it into operation.
The replacement procedure can be accelerated by physically transferring the removable E93DZM memory module from the original drive directly into the replacement regulator. If the original memory module is corrupted or missing, parameter sets and compiled applications must be uploaded using Global Drive Control (GDC) v4.x+ or Drive PLC Developer Studio (DDS) v2.x+. Ensure that any plug-in fieldbus module (such as PROFIBUS-DP or EtherCAT) installed on the AIF slot is moved to the replacement unit and that node addresses and bus termination settings are matched.
