Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13481738 (model EVS9322-CPV003) is a 0.75 kW servo drive belonging to the Lenze 9300 Servo Inverters series. Designed for high-dynamic motion control, this unit utilizes field-oriented vector control to drive both synchronous and asynchronous AC servo motors in automated machinery such as packaging lines, materials handling systems, and textile equipment. Featuring a specialized Cold Plate (CPV003) construction, the drive relies on mounting directly onto external liquid-cooled plates or custom heatsinks for heat dissipation, allowing for compact control cabinet dimensions. It operates across a 3-phase mains supply range of 320 V to 528 V AC (400 V AC nominal), delivering a continuous output current of 2.5 A at an 8 kHz switching frequency and a peak overload current of 3.75 A for up to 60 seconds.
Integration into industrial control networks is established via the built-in Lenze Systembus CAN interface. Additional fieldbus connectivity is achieved using Option Slot A, which supports plug-in automation modules such as PROFIBUS-DP (EMF2133IB / DMF21A), INTERBUS (EMF2111IB), and LECOM (EMF2102IB), while Option Slot F accommodates auxiliary functions or localized I/O. Engine feedback and control lines connect via the dedicated resolver input on connector X7, digital frequency encoder interface, control I/O terminals, and a programmable ready/fault relay output. Commissioning a replacement unit requires restoring the parameter configuration, as up to four complete parameter sets are saved in non-volatile internal EEPROM. When replacing a failed unit, parameter files must be loaded via Global Drive Control (GDC) software or copied using a Keypad XT operator panel. ABC Industrial Parts can assist with parameter backup extraction from existing hardware or supplying pre-configured exchange drives.
Diagnostic state evaluation is available through status LEDs located on the front panel, where a solid red LED signals a TRIP fault, a flashing green LED indicates ready or normal operating status, and a solid yellow LED highlights active controller inhibit (IMP/CINH). Detailed fault analysis can be performed via the 4-digit display on the optional Keypad XT or through GDC diagnostic tools, inspecting parameter C0003 for the TRIP fault history log and parameter C0009 for status codes. Typical external fault codes include OC1 for output short circuits, OU/LU for DC bus voltage thresholds, and OH/OH4/OH7 for temperature limits across the heatsink, motor, or interior. When critical internal hardware codes like EE or H05 occur, field repairs are generally not feasible; acquiring a tested exchange unit or utilizing board-level repair services from ABC Industrial Parts offers a direct path back to full operational capability.

Programming and Configuration
Programming and parameter setting for the Lenze EVS9322-CPV003 are conducted using Global Drive Control (GDC) software or directly via the handheld Keypad XT (EMF2102IB) operator panel equipped with a 4-digit display. The drive features an integrated non-volatile EEPROM memory capable of storing up to four distinct parameter sets, allowing versatile operational profile selection without requiring external controller intervention.
Commissioning a replacement drive requires uploading the application parameter set from GDC or transferring stored parameters via the Keypad XT module. Important parameter memory areas include C0003, which records the TRIP log history of past faults, and C0009, which monitors real-time drive operational status. Ensuring parameter alignment between the original drive and the spare unit is necessary to preserve motor thermal limits, ramp times, and fieldbus communication settings.
Communication and System Integration
The Lenze 13481738 servo drive features built-in system networking through the Lenze Systembus CAN interface, facilitating high-speed deterministic coordination between multiple drive axes. For centralized controller architectures, the drive includes two expansion slots: Option Slot A and Option Slot F. Slot A accommodates fieldbus modules such as PROFIBUS-DP (EMF2133IB / DMF21A), INTERBUS (EMF2111IB), or LECOM (EMF2102IB), integrating the inverter into broader machine control networks.
Hardware interfacing includes terminal connections for digital control I/O, a programmable relay output for ready and fault signaling, and an integrated digital frequency encoder interface. Motor feedback relies on a dedicated resolver input connected at terminal X7, providing precise velocity and position feedback essential for field-oriented vector control.
Diagnostics and Status Indication
Status monitoring for the EVS9322-CPV003 drive is managed visually via front-panel LEDs and digitally using attached operator interfaces. A solid red LED indicates a drive TRIP fault condition, a flashing green LED confirms normal ready state, and a solid yellow LED signals active controller inhibit (IMP / CINH).
In-depth diagnostic routines are supported through the Keypad XT 4-digit display or GDC software oscilloscope and parameter monitoring tools. Parameter C0003 retains recent TRIP fault records to assist technicians during troubleshooting, while parameter C0009 displays active drive status codes.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (Fault) | Red - Solid | Indicates drive TRIP condition or active fault |
| Green LED (Ready) | Green - Flashing | Normal operation / controller ready |
| Yellow LED (Inhibit) | Yellow - Solid | Controller inhibit active (IMP / CINH) |
Replacement and Spare Part Considerations
When replacing an existing Lenze 13481738 EVS9322-CPV003 servo drive, thermal mounting procedures are critical due to its Cold Plate cooling design (CPV003). The rear mounting plane must be clean, flat, and treated with thermal conductive compound before fastening to an external liquid-cooled plate or heavy heatsink. Inadequate thermal dissipation will trigger heatsink overtemperature trips (OH).
Modernization or direct replacement must account for fieldbus modules installed in Option Slot A and Slot F, which should be physically transferred to the replacement chassis. In addition to hardware swapping, parameter configurations stored in the EEPROM must be uploaded using GDC software or Keypad XT prior to putting the machine back into service. For strategic facility upgrades, modern replacement paths include the Lenze i950 or 9400 HighLine servo series.

Frequently Asked Questions
How do I transfer parameters to a replacement Lenze EVS9322-CPV003 drive?
Parameters stored in the drive's internal EEPROM can be transferred using Global Drive Control (GDC) software connected via PC cable or copied directly using the Keypad XT (EMF2102IB) operator panel.
What cooling installation is required for the Cold Plate EVS9322-CPV003 model?
The Cold Plate design (CPV003) lacks an internal heatsink and fan assembly and must be mounted flush against an external liquid-cooled cooling plate or specialized external heatsink using thermal paste to ensure adequate heat dissipation.
What fieldbus communication options are supported on the Lenze 13481738?
The drive includes an integrated Lenze Systembus CAN interface and supports Option Slot A plug-in modules, including PROFIBUS-DP (EMF2133IB / DMF21A), INTERBUS (EMF2111IB), and LECOM (EMF2102IB).
What does a solid red LED indicate on the Lenze EVS9322-CPV003?
A solid red fault LED indicates that the drive is in a TRIP condition due to an active hardware or operational fault. Specific fault codes can be read from parameter C0003 or via the Keypad XT display.
How do I clear an EEPROM fault (EE) or internal error (H05)?
Reset the drive to factory defaults and power cycle the unit. If the EE or H05 error persists after resetting, internal EEPROM memory corruption or control board failure has occurred, requiring unit repair or replacement.
