Lenze EVS9323-CKV003 9300 Servo Cam Profiler Controller
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9323-CKV003 is a 1.5 kW servo controller within the Lenze 9300 Servo family, specifically built as a 9300 Cam Profiler variant. Designed with an IP20 protection rating, this drive operates on a three-phase AC supply voltage ranging from 320 V AC to 528 V AC, delivering a continuous output current of 3.9 A at an 8 kHz chopper frequency with a maximum overload current of 5.9 A for up to 60 seconds. Utilizing an internal Digital Signal Processor, the unit processes electronic cam profiling and multi-axis master-follower synchronization directly at the drive level, providing controlled output frequencies across a range of 0 Hz to 480 Hz.
Interface connectivity features an onboard Lenze System Bus (CAN) supporting communication speeds up to 500 kbit/s, along with a modular Automation Interface slot for plug-in fieldbus modules including the EMF2133IB PROFIBUS, EMF2175IB CANopen, or EMF2173IB DeviceNet cards. Feedback connections accept 2-pole or multi-pole resolvers, incremental encoders, and Sin/Cos encoders via Sub-D connectors, supported by 5 digital inputs, 2 digital outputs, 2 analog inputs, and 2 analog outputs. Commissioning a replacement controller requires parameter transfer, as application settings and up to four switchable parameter sets stored in internal non-volatile EEPROM must be downloaded using Lenze Global Drive Control software, EASY Starter, or an optional XT Keypad EMZ9371BC. Technical assistance and tested exchange modules from ABC Industrial Parts can support parameter backup and device configuration during replacement.
Operational status and drive conditions are indicated by two front-panel LEDs, where the green LED confirms operational readiness or active drive enabling, and the red LED alerts operators to a drive trip or fault state. Specific diagnostic details and historical events can be retrieved via parameter C0168 using the XT Keypad display or software diagnostics monitor. Typical error codes include short circuits (OC1), DC bus overvoltage (OU), resolver feedback errors (Sd1), and CAN communication interruptions (CE0). While wiring errors, supply issues, or missing bus termination can be resolved during routine maintenance, internal errors such as memory failure (EE) or hardware faults (H10) represent non-serviceable electronic failures that require unit replacement or repair through ABC Industrial Parts.

Programming and Configuration
Engineering and parameter management for the Lenze EVS9323-CKV003 is performed using Lenze Global Drive Control (GDC) or EASY Starter programming software. Up to four complete parameter sets can be stored inside internal non-volatile EEPROM memory, allowing complex multi-recipe drive profiling and rapid parameter set switching without continuous downloading from a higher-level controller.
For direct machine-side servicing, the optional XT Keypad (EMZ9371BC) connects to the front interface slot. The keypad permits manual parameter entry, status monitoring, and direct cloning of drive configurations when replacing units in the field.
Communication and System Integration
System connectivity includes an integrated Lenze System Bus (CAN) operating at transmission rates up to 500 kbit/s for high-speed cross-communication between interconnected drives and master controllers. Dedicated Sub-D terminals accommodate various motor feedback interfaces, supporting 2-pole or multi-pole resolvers as well as incremental and Sin/Cos optical encoders.
The drive includes a modular Automation Interface (AIF) slot designed to receive fieldbus expansion cards. Optional plug-in modules include the EMF2133IB PROFIBUS module, EMF2175IB CANopen module, EMF2173IB DeviceNet module, and INTERBUS options, allowing seamless integration into diverse PLC architecture environments.
Diagnostics and Status Indication
Visual status indication is provided by two LEDs on the drive casing. The green LED signals operational readiness and active running states, while the red LED alerts personnel to active trip conditions and system faults.
Fault diagnostic logs are stored internally and accessed via parameter C0168. Technicians can review current and historical error conditions using the XT Keypad EMZ9371BC display or through live diagnostic tools within Lenze Global Drive Control software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready (Green) | Green - Blinking / Solid | Blinks when controller is ready for operation; continuous green when enabled and running normally. |
| Fault (Red) | Red - Solid / Flashing | Lit or flashing red indicates drive trip or active fault condition. |
Replacement and Spare Part Considerations
When replacing an existing Lenze 9300 drive module, verify that the replacement match includes the full part number suffix EVS9323-CKV003. The -CK designation denotes the specific integrated electronic cam profiler functionality; substituting a standard servo drive variant without cam profiler functionality will result in missing motion control features.
Before commissioning a spare unit, transfer all machine parameter sets from the donor or failed drive using GDC software or the XT Keypad. If an optional AIF communication card (such as PROFIBUS or DeviceNet) is installed in the original unit, it must be physically transferred to the replacement module, and network address settings and 120 Ohm CAN bus termination resistors must be confirmed.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short Circuit | Short circuit at the output terminals or instantaneous motor overcurrent. | Short circuit in motor cable; motor winding insulation failure; acceleration time set too short. | Check motor and cable for short circuit or earth fault; check ramp-up times; verify motor rating. |
