Lenze EVS9322-EKV004 9300 Servo Cam Profiler Controller
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9322-EKV004 is a 0.75 kW servo controller from the 9300 Series, specifically configured as a 9300 Servo Cam Profiler. Operating on a mains supply voltage range of 320 V AC to 528 V AC at 45 to 65 Hz, this IP20 panel-mount drive delivers a continuous output current of 2.5 A with a peak current capacity of 3.75 A for dynamic acceleration phases. Built for precise multi-axis positioning and electronic camming applications, the unit integrates specialized motion profiling capabilities directly into the drive hardware, eliminating the need for mechanical cam assemblies or external high-speed motion controller cards.
Interfacing the EVS9322-EKV004 with automated machinery relies on its onboard CAN system bus, dual expansion slots, digital and analog I/O terminals, and resolver feedback on connector X7. Commissioning a replacement unit requires transferring machine-specific parameters and electronic cam profile tables, as a factory-fresh unit will not operate machine motion without prior setup. Parameter sets and cam tables stored in non-volatile memory can be restored using Lenze Global Drive Control (GDC) software version 4.x or higher, or copied directly using the optional EMF2102IB XT keypad module. When parameter extraction from a damaged drive or existing storage media is required, ABC Industrial Parts can assist in preparing replacement drives for fast installation.
Diagnostic information on the drive state is provided via front-panel status LEDs and software monitoring tools. A solid green LED indicates controller enable and drive readiness, whereas a flashing green LED signifies an inhibited controller or warning condition; a solid or flashing red LED signals a TRIP fault state. Detailed fault entries can be evaluated through the TRIP memory log using Lenze GDC software or the XT keypad, giving precise causes for errors such as heatsink overtemperature (OH), DC bus overvoltage (OU), or communication loss (CE0/CE1). Initial troubleshooting should focus on input power stability, 120 Ohm CAN bus termination, resolver feedback cabling on connector X7, and fieldbus module seating in Slot A. If hardware self-test faults such as H05 occur, internal component failure cannot be serviced on site, making drive replacement or expert repair through ABC Industrial Parts necessary to restore production.

Programming and Configuration
Configuring the Lenze EVS9322-EKV004 servo drive is executed through Lenze Global Drive Control (GDC) software version 4.x or higher, connected via the system bus interface or diagnostic adapter. GDC software enables engineers to build, recalculate, and modify complex electronic cam profile tables, set operating parameters, and configure drive control structures for application-specific task execution.
The drive features internal non-volatile EEPROM storage capable of retaining up to four independent parameter sets alongside custom motion profile data tables. For field-level adjustments or parameter transfers without a computer, the pluggable Lenze EMF2102IB XT keypad module allows maintenance personnel to upload, download, and store complete parameter sets directly at the cabinet panel.
Communication and System Integration
System communication for the Lenze EVS9322-EKV004 centers around an integrated CAN system bus supporting data transmission rates from 10 kbps up to 500 kbps. This onboard network facilitates inter-drive synchronization, master frequency coupling, and multi-axis speed or position coordination across complex machine setups without external motion controller cards.
To integrate into higher-level plant automation networks, the drive includes dual expansion slots. Slot A accepts pluggable fieldbus automation modules such as the EMF2133IB PROFIBUS-DP module, DeviceNet modules, or INTERBUS options. The dual-slot layout allows simultaneous fieldbus control and local function expansion, ensuring compatibility with diverse PLC architectures.
Diagnostics and Status Indication
The EVS9322-EKV004 incorporates dual LED indicators on the front panel alongside diagnostic software routines for rapid status verification. The green status LED indicates operational readiness when solid and controller inhibition or warning conditions when flashing. The red status LED illuminates or flashes upon detecting active fault conditions or TRIP states.
Detailed diagnostic records are maintained in an internal TRIP memory log accessible through the Lenze GDC Diagnostic Window or the EMF2102IB XT Keypad Module. The controller also supports diagnostic output signaling by assigning internal TRIP or fault status bits to physical digital outputs or relay contacts for external PLC alarm integration.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Solid or Flashing | Indicates a fault condition or TRIP state |
| Green LED | Green - Solid or Flashing | Solid indicates controller enable and drive ready; Flashing indicates controller inhibited or warning state |
Replacement and Spare Part Considerations
When replacing a failed Lenze EVS9322-EKV004 drive, ensure the replacement unit matches the exact part number and functional variant code (V004), as hardware variants differ in internal motion capabilities and software processing modules. Physical mounting dimensions and terminal layout match standard 9300 Series IP20 units of identical frame size.
A replacement unit must be loaded with the machine's parameter set and electronic cam profile tables before powering up the drive outputs. Parameters can be restored from a software backup using Lenze GDC software V4.x+ or transferred directly from a donor unit using an EMF2102IB XT keypad module.
Verify that option modules in Slot A (such as an EMF2133IB PROFIBUS-DP module) are correctly transferred and firmly seated in the replacement unit. Ensure the CAN system bus line is terminated with 120 Ohm resistors at both physical ends of the bus to prevent communication errors such as CE1 upon startup.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OH | Heatsink Temperature High | Drive heatsink temperature has exceeded maximum permissible limit (> 90 °C). | Inadequate cooling, fan failure, ambient temperature too high, continuous excessive overload. | Check cabinet ventilation, clean cooling fins, verify ambient temperature is within range, inspect internal fan. |
| OH4 | Motor Temperature Switch Open | Motor thermal contact or PTC thermistor circuit triggered. | Motor overheating, thermal contact open (terminals T1/T2), motor sensor wire disconnected. | Allow motor to cool down, check motor load, verify wiring on terminals T1/T2. |

| LU | DC Bus Undervoltage | DC bus voltage dropped below minimum operating limit (~400 V DC). | Mains voltage supply failure, phase loss, power drop under load. | Check mains voltage input, inspect fuses, check power connections and supply transformer. |
| OC1 | Short Circuit / Earth Fault | Instantaneous overcurrent trip triggered by short circuit or ground fault. | Short circuit in motor cable, motor winding fault, earth/ground fault on output terminals U/V/W. | Check motor and output wiring for insulation resistance and short circuits. If fault persists with motor disconnected, internal power stage failure - return unit for repair. |
| OC2 | Overcurrent during Acceleration | Output current exceeded peak limit during motor acceleration. | Acceleration ramp set too steep, motor mechanically blocked, incorrect motor data. | Increase acceleration time, check motor for mechanical binding, verify motor parameters. |
| OC5 | Ixt Overload | Drive load integral (Ixt overload) exceeded allowable threshold. | Continuous operation above rated current (between 100% and 150% load). | Reduce mechanical load, select larger servo controller size if process requires continuous high torque. |
