Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9326-EIV907 is an 11 kW panel-mount servo controller from the 9300 Servo PLC family, designed to combine motion control and programmable logic inside a single IP20 housing. Operating on a 3-phase AC supply voltage between 320 V and 528 V AC, the drive delivers a continuous output current of 23.5 A at an 8 kHz switching frequency and supports a 150% peak current overload of 35.3 A for up to 60 seconds. By incorporating an IEC 61131-3 compliant internal PLC directly into the inverter structure, the EVS9326-EI V907 handles multi-axis positioning, synchronized web processing, and dynamic packaging automation without requiring separate central controller hardware.
Interfacing the unit into a machine control architecture involves standard terminal connections alongside dedicated feedback ports, including Sub-D connectors for resolver and master incremental encoder inputs, as well as 8 digital inputs, 4 digital outputs, 2 bipolar analog inputs, and 2 bipolar analog outputs. High-speed inter-drive network traffic is supported over an onboard CANopen system bus via terminal strip X14 at speeds up to 500 kbps, while an Automation Interface (AIF) slot accommodates optional fieldbus modules such as the EMF2133IB PROFIBUS-DP module. Commissioning a replacement unit requires restoring the parameter settings—up to four complete parameter sets can be stored in internal memory—and reloading the compiled PLC program code developed in Drive PLC Developer Studio (DDS) using Global Drive Control (GDC) software or an EMF2102IB Keypad XT operator module. Where existing files are unavailable, technical teams at ABC Industrial Parts can assist in extracting configuration data from a damaged unit to ensure identical motion profiles and parameter alignment on the replacement drive.
Real-time diagnostic feedback is provided by three front-panel status LEDs, indicating drive ready status with a solid green DRV-READY light, pulse inhibit via a yellow IMP light, and active fault conditions with a red DRV-ERR light. System diagnostics can also be interrogated through the optional Keypad XT module, CANopen status registers, or live monitoring in GDC and DDS software environments. Fault codes such as LU (DC bus undervoltage), OU (DC bus overvoltage), OH (heatsink overtemperature), and OC1 (acceleration overcurrent) indicate external power line, thermal, or wiring anomalies that can be resolved by checking supply voltages, cabinet ventilation, and motor cabling. Communication errors like CE0 or CE1 highlight CAN termination or AIF option module seating issues, whereas internal diagnostic codes like H05 hardware faults or persistent EEr memory errors signal board-level issues that are not field-serviceable. In these instances, obtaining a tested replacement unit or utilizing repair services through ABC Industrial Parts provides a rapid resolution to restore machine operation.

Programming and Configuration
The Lenze EVS9326-EIV907 combines logic execution and servo control through an integrated IEC 61131-3 compliant Drive PLC. Engineering and application development are executed using Lenze Drive PLC Developer Studio (DDS) software, which allows custom application code, positioning tasks, and logic routines to be written and compiled directly for the controller runtime environment. Drive commissioning, standard parameter assignment, and real-time trace functions are performed via Global Drive Control (GDC) software connected through a PC System Bus Adapter such as the EMF2177IB or EMF2173IB.
The controller features internal non-volatile memory capable of retaining up to four distinct parameter sets along with the compiled DDS logic program. Parameters can be copied, edited, and saved using the optional EMF2102IB Keypad XT operator module plugged directly into the drive interface slot, allowing fast field parameterization without requiring a laptop connection.
When replacing a unit in production, both the parameter sets and the DDS application project code must be restored to match the physical machine configuration. If a PR0 fault code appears during operation, it indicates a runtime logic error inside the internal PLC code, requiring application engineers to connect via DDS, debug the runtime exception, and re-download the corrected project code to the drive memory.
Communication and System Integration
System integration for the EVS9326-EIV907 is facilitated through an integrated CANopen system bus interface accessible on terminal strip X14. Operating at transmission rates up to 500 kbps, this system bus enables fast inter-drive synchronization, multi-axis master-slave arrangements, and direct peer-to-peer data interchange across complex automated machinery. Proper network layout requires standard 120-ohm termination resistors at each physical end of the CAN network.
For broader factory automation networks, the drive includes a pluggable Automation Interface (AIF) slot designed for fieldbus communication modules. Installing an optional EMF2133IB module enables direct connectivity to PROFIBUS-DP networks, while alternative option modules allow integration into DeviceNet or INTERBUS control systems. These modules interface directly with the internal drive control registers and PLC runtime variables.
Physical signal integration is handled through terminal connections providing 8 freely programmable 24 V DC digital inputs, 4 digital outputs, 2 bipolar analog inputs, and 2 bipolar analog outputs. Closed-loop position and velocity feedback connections are provided via dedicated Sub-D connectors, supporting standard resolver feedback on connector X7 as well as master incremental encoder inputs.
Diagnostics and Status Indication
The EVS9326-EIV907 provides clear visual and digital diagnostic feedback to simplify troubleshooting during installation and normal operation. The front cover features three status LEDs that immediately show the operational status of the power stage, logic runtime, and fault conditions. Detailed status registers and error history logs are accessible over the CANopen bus or through the online diagnostic monitor within Global Drive Control (GDC) and Drive PLC Developer Studio (DDS) software.
When fitted with an optional EMF2102IB Keypad XT module, specific diagnostic codes and error messages are rendered directly on the display. In addition to monitoring real-time operating variables like DC bus voltage and motor speed, the keypad displays clear error codes when fault conditions trip the drive's protective functions.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRV-ERR | Red - Solid/Flashing | Fault state / Active error present in the controller |
| DRV-READY | Green - Solid | Controller ready for operation / Inverter enabled |
| IMP | Yellow - Solid | Pulse inhibit active (power stage disabled) |
Replacement and Spare Part Considerations
When substituting an existing drive with a replacement Lenze EVS9326-EIV907 unit, verification of both hardware model type and power ratings is critical. The replacement drive must match the EVS9326-EI V907 designation to guarantee compatibility with the 11 kW output stage, 23.5 A continuous output current rating, and 320–528 V AC input supply range.
Because the unit integrates an onboard PLC, a bare replacement drive will not operate in the machine until both the device parameters and the IEC 61131-3 logic program are downloaded. Any optional fieldbus cards, such as the EMF2133IB PROFIBUS-DP module, must be transferred from the original unit to the replacement drive's AIF slot, ensuring address settings and bus wiring match the host network master configuration.
Before restoring power to the replacement unit, verify proper grounding and cable shield connections on resolver input X7 and motor power terminals. Ensure that line voltage levels are within limits and verify that the 120-ohm CAN bus termination resistors are correctly engaged on terminal strip X14 if the drive forms part of a multi-axis system bus topology.
