Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13325136 (model EVS9323-ES) is a 1.5 kW servo inverter from the 9300 Servo Drives family designed for dynamic speed, torque, and position control in automated equipment. Operating from a 3-phase AC line supply between 320 V and 528 V AC, this compact drive unit delivers a continuous rated output current of 3.9 A and supports peak currents up to 5.9 A with a 150% dynamic overload capacity for 60 seconds. Utilizing high-performance field-oriented vector control across an output frequency range of 0 to 480 Hz and output voltages of 0 to 400/480 V AC, it controls permanent magnet synchronous servo motors and asynchronous induction motors in packaging, material handling, automotive assembly, and machine tool machinery.
Interfacing the EVS9323-ES with control systems is facilitated by an onboard Sub-D resolver motor feedback interface, master frequency encoder input/output connections, and an integrated CAN System Bus port on terminal X14 supporting communication speeds up to 500 kbit/s. For expanded fieldbus connectivity, a front Automation Interface (AIF) slot accepts optional modules such as PROFIBUS DP (EMF2133IB), Interbus (EMF2105IB), or DeviceNet (EMF2175IB). Putting a spare drive into service requires parameter transfer, as internal non-volatile EEPROM storage maintains up to four independent parameter sets. Settings can be cloned using the pluggable XT Keypad (EMF2102IB) or Global Drive Control (GDC) software via a PC System Bus Adapter (EMF2171IB or EMF2177IB). ABC Industrial Parts can assist in sourcing fully tested drives and transferring configurations to keep production lines running smoothly.
System diagnostic conditions are reflected via front panel status LEDs, the XT Keypad display, and the GDC software diagnostic monitor. A solid green LED indicates that the drive controller is enabled and running, while a flashing green LED signifies drive inhibit (CINH) or controller disable. A flashing red LED signals an active TRIP fault state, while remaining off during normal operation. Operational issues such as DC bus overvoltage (OU), undervoltage (LU), phase failures (LP1, LP2), or thermal overloads (OH, OH3, OH4) are logged in internal memory registers C0168 and C0170. When hardware self-test faults such as H05, H10, or H11 occur, internal control hardware or sensor failures are present that cannot be repaired in the field; in these scenarios, ABC Industrial Parts offers replacement units and repair options to eliminate extended downtime.

Programming and Configuration
Programming and parameter management for the Lenze EVS9323-ES servo inverter are performed using Lenze Global Drive Control (GDC) software or the pluggable XT Operating Keypad (EMF2102IB). The unit features internal non-volatile EEPROM memory engineered to store up to four complete, independent parameter sets. This capability permits easy switching between different machine operating profiles or straightforward parameter replication when swapping hardware.
Connecting a PC for configuration requires an interface adapter such as the Lenze PC System Bus Adapter (EMF2171IB or EMF2177IB). In the event of power loss during a write cycle, memory corruption can trigger fault code C013 (Parameter Set Error). Resolution requires restoring factory defaults by setting code C0002 to 1 and re-downloading a validated parameter configuration back into the drive EEPROM.
Communication and System Integration
Network integration and multi-axis synchronization on the Lenze EVS9323-ES are driven by an onboard CAN System Bus interface at terminal connector X14. Capable of baud rates up to 500 kbit/s, the CAN bus supports direct drive-to-drive communication, parameter transfer, and real-time motion alignment. Physical installation requires shielded twisted-pair cabling, appropriate node ID addressing, matching bus speeds, and 120-ohm termination resistors at the physical ends of the communication line.
For connection to broader plant networks, the unit features a modular Automation Interface (AIF) slot on the front panel. This slot accommodates option cards including PROFIBUS DP (EMF2133IB), Interbus (EMF2105IB), and DeviceNet (EMF2175IB). Integrated master frequency encoder input and output terminals allow master-slave frequency cascading, enabling precise speed ratio synchronization across multiple drive units.
Diagnostics and Status Indication
Real-time monitoring of operational status and fault management on the EVS9323-ES is conducted through visual LEDs, keypad displays, and software tools. Two front-panel status LEDs provide immediate physical feedback regarding controller status and TRIP fault state. Internal fault history memory codes C0168 and C0170 capture diagnostic events, while code C0161 logs CAN system bus communication statuses.
For detailed fault analysis and live signal monitoring, technicians can attach the pluggable XT Keypad (EMF2102IB) or establish a direct connection using Global Drive Control (GDC) software on a PC. This software interface allows online parameter inspection, diagnostic register readout, and real-time motor status tracing.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Flashing / Off | Flashing indicates active drive fault (TRIP). Off indicates normal operation. |
| Green LED | Green - Solid / Flashing | Solid ON indicates drive enabled and running. Flashing indicates drive inhibit (CINH) or controller disable. |
Replacement and Spare Part Considerations
When installing a replacement Lenze EVS9323-ES (13325136) drive into an existing 9300 series setup, hardware compatibility must be ensured. Verify that the replacement drive matches the required 1.5 kW output rating, 3.9 A continuous current, and 320–528 V AC input supply. Any front-mounted communication module, such as a PROFIBUS DP card (EMF2133IB), must be swapped from the original unit into the replacement's AIF slot.
Because a spare unit will not carry application-specific configuration upon arrival, active parameters stored in the internal EEPROM of the failed drive must be cloned. This is done by transferring the configuration via the XT Keypad (EMF2102IB) or downloading the saved parameter set using Lenze Global Drive Control (GDC) software via a PC System Bus Adapter (EMF2171IB or EMF2177IB). Ensure CAN bus node addresses, baud rates, and resolver feedback parameters are fully validated before powering up the drive.

Frequently Asked Questions
How do I transfer parameter settings to a replacement Lenze EVS9323-ES drive?
Parameter settings can be transferred by copying them with an XT Keypad (EMF2102IB) or uploading/downloading the parameter set using Lenze Global Drive Control (GDC) software connected via a PC System Bus Adapter (EMF2171IB or EMF2177IB). The parameters must be written to non-volatile EEPROM storage on the replacement unit.
What do the green and red status LEDs indicate on the front panel?
The green LED indicates controller operating status: solid ON means the drive is enabled and running, while flashing indicates drive inhibit (CINH) or controller disable. The red LED flashes when an active TRIP fault condition exists and remains off during normal operation.
What causes an OU fault code on the EVS9323-ES and how is it resolved?
An OU fault code signifies a DC bus overvoltage condition exceeding 770 V DC, typically caused by regenerative energy during fast deceleration or a missing/defective braking resistor. To resolve it, extend the deceleration ramp time or check/install a properly rated external braking resistor.
What communication interfaces are integrated into the EVS9323-ES?
The drive features an integrated CAN System Bus interface on terminal X14 supporting up to 500 kbit/s. Higher-level fieldbus support is added via the modular front AIF slot using cards such as PROFIBUS DP (EMF2133IB), Interbus (EMF2105IB), or DeviceNet (EMF2175IB).
How should internal hardware faults like H05, H10, or H11 be resolved?
Fault codes H05, H10, and H11 indicate internal self-test failures within the control board, power circuit, or internal temperature sensors. These hardware errors cannot be serviced in the field and require unit repair or replacement with a tested exchange drive.
Which motor feedback types are directly supported by the drive?
The EVS9323-ES includes an onboard Sub-D resolver feedback connection for position and speed feedback, as well as master frequency encoder input/output terminals for frequency cascading.
