Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13015967 EVS9322-EPV004 is a 0.75 kW servo positioning controller within the Lenze 9300 Servo family, engineered for precise motor control and integrated positioning logic in automated drive systems. Operating on a 3-phase AC supply voltage ranging from 320 V AC to 528 V AC (400/480 V nominal), the unit provides a continuous output current of 2.5 A and a maximum peak current of 3.75 A for up to 60 seconds at an 8 kHz switching frequency. By combining high-dynamic servo drive control with digital positioning software functionality, this unit manages point-to-point positioning, synchronized motion, and speed or torque control without requiring an external positioning controller.
For machine connectivity and feedback processing, the EVS9322-EPV004 features a 9-pin Sub-D resolver connector alongside master frequency and encoder input/output connections. Drive-to-drive communication is provided via an onboard CAN system bus operating at speeds up to 500 kbit/s, while an integrated Automation Interface (AIF) slot accommodates optional fieldbus communication modules such as PROFIBUS-DP (EMF2112IB / EMF2113IB), INTERBUS (EMF2102IB), and LECOM RS-232/RS-485. Commissioning a replacement unit requires transferring machine parameter sets stored in the non-volatile internal EEPROM, which holds up to four distinct parameter configurations. Engineers can configure settings and upload backups using Lenze Global Drive Control (GDC) software or the plug-in XT Operating Module Keypad (EMF2101IB). ABC Industrial Parts can support maintenance teams with parameter extraction and pre-configuration when preparing a replacement drive for service.
System status and operating diagnostics are indicated through tri-color status LEDs and recorded in internal diagnostic history codes C0168 and C0170. The green LED signals controller operation or inhibit status, yellow indicates active impulse inhibit or current limit status, and red alerts technicians to warning or TRIP fault conditions. Standard fault codes—such as OC1 for overcurrent, OU for DC bus overvoltage, LU for undervoltage, and rSO or Sd7 for feedback signal faults—allow rapid identification of external wiring or motor issues. However, if the red LED remains solid on power-up with no display communication, or if fault code H05 or persistent EER errors occur, an internal board or control component failure is present. Because internal hardware faults cannot be serviced in the field, exchanging the failed unit with a tested spare from ABC Industrial Parts offers the most efficient path back to full production.

Programming and Configuration
Programming and parameter setup for the Lenze 13015967 EVS9322-EPV004 are conducted through Lenze Global Drive Control (GDC) software or directly via the portable XT Operating Module Keypad (EMF2101IB). The drive houses internal non-volatile EEPROM memory capable of retaining four complete, independent parameter sets. This multi-configuration storage simplifies multi-product line switching and allows comprehensive parameter backups to be retained directly inside the drive hardware.
When commissioning a replacement unit or restoring system operation, parameter sets must be transferred to mirror the exact settings of the original drive, including motor feedback parameters, positioning profiles, acceleration ramps, and fieldbus node addresses. If parameter data cannot be read directly via GDC or the keypad interface due to internal control faults, technical extraction from internal storage may be required prior to deploying the replacement unit.
Communication and System Integration
The Lenze EVS9322-EPV004 provides native networking functionality through its onboard CAN system bus, supporting communication speeds up to 500 kbit/s. This system bus facilitates rapid drive-to-drive synchronization, direct parameter interchange, and status word inspection across distributed multi-axis drive architectures in high-speed packaging and material handling applications.
Higher-level PLC and host automation system integration is achieved through the integrated Automation Interface (AIF) slot located on the front of the drive. The AIF slot accepts plug-in fieldbus modules including PROFIBUS-DP interfaces (EMF2112IB and EMF2113IB), INTERBUS interfaces (EMF2102IB), and LECOM RS-232/RS-485 modules. Motor feedback signals are captured via dedicated dual feedback processing, supporting standard resolvers through a 9-pin Sub-D connector as well as incremental encoder inputs and outputs.
Diagnostics and Status Indication
Visual monitoring of the Lenze EVS9322-EPV004 is performed via three front-mounted LEDs that reflect operational and fault states. In addition to visual indication, detailed operational status and historical diagnostic events are tracked inside the drive's memory. Technicians can access TRIP history buffers using codes C0168 and C0170 via the XT Keypad or GDC software, or inspect status words across the CAN bus and connected fieldbus networks.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED | Green - Solid / Blinking | Drive operation state: ON = Drive enabled / running; Blinking = Controller inhibit (ready for operation). |
| Red LED | Red - Solid / Blinking | Fault state / TRIP condition: ON = Fault active (drive tripped); Blinking = Warning active. If Red LED remains solid upon power up with no display communication, indicates internal board/hardware failure requiring repair. |
| Yellow LED | Yellow - Solid | Impulse inhibit active or current limit reached. |
Replacement and Spare Part Considerations
Replacing a Lenze EVS9322-EPV004 servo positioning controller requires matching the exact part number 13015967 and model designation EVS9322-EPV004 to ensure full compatibility with existing 3-phase 400/480 V AC power connections, 2.5 A continuous current ratings, and motor feedback wiring. Because this drive integrates dynamic servo control with digital positioning tasks, a replacement unit cannot be put into immediate operation without loading the correct machine configuration.
Prior to powering up the machine, the replacement unit must be loaded with the machine-specific parameter set saved from the original controller or restored from a software backup using Lenze GDC software or an XT Keypad (EMF2101IB). Maintenance personnel must also verify that any optional fieldbus communication cards, such as PROFIBUS-DP or INTERBUS modules installed in the original unit's AIF slot, are transferred to slot A on the replacement unit and that bus addresses and baud rates match network requirements.
