Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9323-ES, identified by part number 00402196, is a 1.5 kW servo inverter drive within the Lenze 9300 Servo series designed for high-precision motion control applications. Operating on a 3-phase AC supply voltage from 320 V to 528 V AC (45 to 65 Hz) or a direct DC bus input from 460 V to 740 V DC, this drive provides a continuous output current of 3.9 A and a peak overload current of 5.9 A at an 8 kHz nominal switching frequency. It delivers an output frequency range of 0 to 480 Hz to drive AC servo motors in synchronized multi-axis positioning, web tension control, and dynamic conveyor applications across packaging, printing, textile, and material handling lines.
Interfacing with feedback and control devices is accomplished through dual onboard feedback connections: a Sub-D 9-pin connector X7 for 2-pole or multi-pole resolvers and a Sub-D 15-pin connector X8 for TTL or SinCos incremental encoders, along with an X9 encoder simulation output for master-slave coupling. Network integration includes an onboard CAN system bus interface on terminal X4 supporting transmission speeds up to 500 kbit/s, while an Automation Interface (AIF) slot accommodates optional fieldbus communication modules such as PROFIBUS-DP or LECOM, as well as the Keypad XT user interface module. Placing a spare EVS9323-ES into service requires transferring application parameter sets stored in internal non-volatile EEPROM—which holds up to four independent configurations—using Lenze Global Drive Control (GDC), EASY Starter software, or a Keypad XT module. ABC Industrial Parts offers expert support to assist with parameter backup extraction and transfer from faulty units.
Immediate operational status is displayed via three front-panel LEDs: a solid green READY LED indicating normal operation, a solid yellow WARNING LED signalling threshold warnings, and a solid or flashing red FAULT LED indicating active trip conditions. Diagnostic navigation is managed through parameter codes C0161 to C0170 and a time-stamped fault history buffer retaining the last eight error events accessible via GDC software or the Keypad XT module. Specific fault codes such as overcurrent (OC1, OC2, OC3, OC5), overvoltage (OU), undervoltage (LU), temperature limits (OH, OH3, OH4), or feedback loss (E1, E2) guide targeted physical checks on line power, braking resistors, cooling fans, and encoder cabling. For internal hardware failures such as micro-controller or power stage faults (H05 or H07), field service is not viable, making direct replacement or a tested exchange drive from ABC Industrial Parts the fastest route to restore production.

Programming and Configuration
Parameter setup and application management for the Lenze EVS9323-ES drive are conducted using Lenze Global Drive Control (GDC) or EASY Starter software. The drive relies on a flexible function block architecture that permits custom assignment of internal motion control functions, position loops, and speed profile routines. Operating parameter sets are retained inside integrated non-volatile EEPROM memory, which holds up to four independent parameter sets.
Field parameters can be saved, edited, or backed up directly using the optional plug-in Keypad XT module (EMZ9371BC) mounted on the front Automation Interface (AIF) slot. Keypad XT memory copy functions allow rapid transfer of full parameter files from one drive unit to another without a computer. When loading fresh configurations via software or keypad, executing parameter store routines via code C0002 ensures non-volatile retention.
Communication and System Integration
System integration is facilitated through the onboard CAN system bus interface on terminal X4, which supports baud rates up to 500 kbit/s for synchronized multi-axis master-slave operation and fast parameter interchange. Terminal X4 provides physical CAN transmission line connections that require proper 120-ohm bus termination at both line ends.
Modularity is expanded via the front Automation Interface (AIF) slot, which accepts dedicated communication adapters including PROFIBUS-DP modules (EMF2133IB / EMF2131IB) and LECOM modules (EMF2102IB / EMF2171IB). These communication boards allow the EVS9323-ES to interface with higher-level PLC system architectures, complemented by four onboard digital inputs, two digital outputs, two analog inputs, and two analog outputs.
Diagnostics and Status Indication
Real-time operational feedback is provided on the front interface by three status LEDs indicating readiness, warning conditions, and active fault trips. Parameter monitoring codes C0161 through C0170 expose internal runtime variables, actual motor speeds, DC bus voltages, and load levels.
Fault events are logged in an internal history buffer that stores up to eight past errors alongside time stamp indices, accessible via parameter codes C0183 and C0168 on the Keypad XT or inside the GDC diagnostic window.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| READY | Green - Solid | Drive ready for operation |
| FAULT | Red - Solid or Flashing | Drive fault trip active |
| WARNING | Yellow - Solid | Operating warning threshold reached |
Replacement and Spare Part Considerations
When swapping a damaged unit with a replacement Lenze EVS9323-ES, ensure exact hardware matching across part number 00402196. Crucially, plug-in fieldbus option cards (such as PROFIBUS or LECOM modules) must be unclipped from the front AIF slot of the original unit and transferred directly to the replacement unit.
Because new or spare drives do not ship pre-configured, downloading the machine's specific parameter file using Global Drive Control (GDC) software or transferring the EEPROM data set via a Keypad XT module is required prior to starting the motor. If direct parameter upload is not possible due to hardware failure, technical parameter extraction from donor boards or system backup archives should be utilized.
For modernizing machines containing legacy 9300 series drives, upgrade options include retrofitting to contemporary Lenze i700 or i950 series servo drives, which may require motor wiring and fieldbus network adjustment.

Frequently Asked Questions
How do I back up and transfer parameters to a replacement Lenze EVS9323-ES drive?
Parameters can be transferred using Lenze Global Drive Control (GDC) or EASY Starter software via a PC connection. Alternatively, parameter sets stored in non-volatile EEPROM can be copied directly using a Keypad XT (EMZ9371BC) module attached to the front Automation Interface (AIF) slot.
What feedback devices are supported by the EVS9323-ES drive?
The drive features integrated dual feedback inputs supporting standard 2-pole or multi-pole resolvers via Sub-D 9-pin connector X7 and TTL or SinCos incremental encoders via Sub-D 15-pin connector X8.
How can fieldbus protocols like PROFIBUS or LECOM be connected to this drive?
Communication expansion is achieved via the plug-in Automation Interface (AIF) slot on the front panel. Optional fieldbus modules, such as PROFIBUS (EMF2133IB / EMF2131IB) or LECOM (EMF2102IB / EMF2171IB), snap directly into the slot without requiring main board modifications.
What does fault code H05 or H07 indicate on the Lenze 9300 Servo drive?
Fault code H05 indicates an internal microcontroller or memory hardware error (such as EEPROM checksum failure), while H07 indicates an internal power stage hardware fault. These hardware errors are not field-serviceable and require a power cycle or unit replacement.
What causes a CE0 fault and how is it resolved?
A CE0 code signifies a CAN system bus fault on terminal X4. This is caused by interrupted wiring, bus-off conditions, baud rate mismatches, or missing 120-ohm termination resistors at the physical ends of the CAN line. Resolving it requires inspecting CAN cabling, checking settings, and verifying termination resistors.
