Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9324-EP (part number 13180717) is an industrial position control servo drive from the Lenze 9300 Servo series. Engineered to execute precise motion control tasks without requiring external PLC positioning hardware, this 3.0 kW unit supplies a continuous output current of 9.5 A with a maximum peak output capability of 14.3 A for 60 seconds. Operating on a 3-phase mains voltage between 320 V AC and 528 V AC at 45 Hz to 65 Hz (400/480 V AC nominal), the drive features integrated -EP software functions capable of handling relative and absolute positioning, S-curve profile generation, torque and velocity management, and automated homing routines.
Physical integration is supported through Sub-D 9-pin connectors dedicated to resolver feedback (X7), encoder feedback (X8), and frequency simulator outputs (X9), along with an onboard CAN system bus interface (X4) operating at speeds up to 500 kbit/s for inter-drive synchronization. An internal expansion slot allows connection of fieldbus modules such as PROFIBUS-DP (EMF2133IB/EMF2131IB), DeviceNet (EMF2175IB), or INTERBUS (EMF2102IB). Commissioning a spare or replacement unit requires downloading or transferring parameter sets via Lenze Global Drive Control (GDC) software or an EMZ9371BC keypad operating module. Up to four parameter configurations can be stored in internal non-volatile EEPROM, making correct parameter migration from ABC Industrial Parts key to establishing identical machine behavior.
System diagnostic states are indicated on the unit via status LEDs and can be queried via terminal X5, the keypad interface, or the CAN bus. A green LED indicates operational readiness or drive disablement, while a red LED signals active warnings or trip conditions. An internal fault buffer stores the last eight TRIP fault events complete with timestamps, assisting in the isolation of system trips like heatsink overtemperature (OH), DC bus overvoltage (OU), or resolver line loss (Sd2). When unrecoverable internal failures such as code H05 occur on control or driver boards, field servicing is not possible, making a pre-tested replacement unit or professional repair service from ABC Industrial Parts the most efficient path back to operational capability.

Programming and Configuration
The Lenze 9300 Position Control (-EP) variant embeds motion profiles, S-curve acceleration ramps, and homing commands directly into the drive firmware. Engineering and commissioning are performed using Lenze Global Drive Control (GDC) software connected via a PC adapter (such as EMF2171IB or EMF2177IB) or locally using the detachable EMZ9371BC keypad operating module.
Internal non-volatile EEPROM memory stores up to four complete parameter sets. This feature allows plants to maintain multiple production recipes or operating configurations locally on the drive. When commissioning a replacement drive, user parameters, motor feedback calibration, and motion program parameters must be transferred from a backup file or extracted from the original unit to retain proper positioning functionality.
Communication and System Integration
Network connectivity is anchored by an onboard CAN system bus interface at terminal X4. Supporting transmission speeds up to 500 kbit/s, this interface allows high-speed inter-drive communication and axis synchronization across multi-axis positioning architectures, packaging machinery, and rotary index tables.
For integration into broader industrial control networks, an automation slot accommodates optional fieldbus communication modules, including PROFIBUS-DP (EMF2133IB / EMF2131IB), DeviceNet (EMF2175IB), or INTERBUS (EMF2102IB). Motor feedback and pulse signals are connected via 9-pin Sub-D connectors: terminal X7 for resolver input, terminal X8 for incremental encoder input, and terminal X9 for frequency simulator output.
Diagnostics and Status Indication
The EVS9324-EP incorporates continuous monitoring of internal power stages, temperatures, feedback connections, and bus communications. Diagnostics are accessed locally via two front LEDs, through the EMZ9371BC keypad, over terminal X5 status channels, or via GDC software oscilloscope and status windows.
An onboard diagnostic memory buffer records the last eight TRIP fault events with associated timestamps. This buffer allows maintenance teams to review fault history and identify root causes such as line voltage drops, motor thermal overloads, or position feedback noise.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Ready / Operation) | Green - Solid / Blinking | ON = Inverter ready / normal operating state. Blinking = Drive disabled or operating in restricted mode. |
| Red LED (Fault / Error) | Red - Solid / Flashing | ON or flashing = Active trip or warning present. Continuous red with drive lockout indicates active trip condition. |
Replacement and Spare Part Considerations
When selecting a replacement for an EVS9324-EP drive, matching both the 3.0 kW power section and the specific -EP suffix is required. Standard non-EP variants of the 9300 series do not contain the embedded position control firmware, which will prevent the replacement unit from performing positioning tasks.
Before replacing an existing unit, parameter sets saved in the drive's EEPROM should be uploaded via Global Drive Control (GDC) software or copied using the EMZ9371BC keypad. Any communication modules present in the automation slot (such as PROFIBUS EMF2133IB) must be transferred to the spare unit, confirming that DIP switch addresses and line termination match the original setup.
If the existing drive registers unserviceable hardware faults like code H05 or internal short circuits under code OC1 with the motor disconnected, internal board-level servicing cannot be performed in the field. Installing a fully tested replacement drive or sending the unit for bench repair provides the fastest route to restoring production lines.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OH | Heatsink temperature too high | Heatsink temperature exceeded upper operating limit (>90°C). | Insufficient cooling airflow, cabinet ventilation failure, fan defective, extreme ambient temperature or prolonged drive overload. | Check cabinet ventilation and cooling fans, clean heatsink cooling fins, reduce load or duty cycle. |
| OH3 | Motor thermal sensor trip | Motor temperature sensor (PTC / KTY) reported motor overtemperature. | Motor thermal overload, blocked motor cooling, improper motor sizing or sensor wiring breakdown. | Allow motor to cool down, check motor load, verify PTC/KTY sensor connections at control terminals. |
| OU | DC bus overvoltage | DC bus voltage exceeded maximum allowable threshold (approx. 770 V DC). | Excessive braking energy fed back from motor during deceleration, deceleration ramp time set too short, braking chopper or braking resistor disconnected or defective. | Extend deceleration time, connect external braking resistor, check braking chopper transistor and resistor resistance. |
| LU | DC bus undervoltage | DC bus voltage fell below minimum allowable threshold (approx. 430 V DC). | Mains supply voltage drop, phase loss, blown supply fuse, instability in AC power line. | Check mains voltage across all 3 supply phases, inspect main contactor and power line fuses. |
| OC1 | Overcurrent / Short circuit | Peak output current exceeded trip limit immediately upon pulse enable. | Short circuit in motor windings or motor power cable, ground fault, defective motor insulation, or internal power transistor short circuit. | Disconnect motor cables and measure winding and phase-to-ground insulation resistance. If fault persists with motor cable disconnected, internal hardware fault — replace unit or return for repair. |
| OC2 | Overcurrent during acceleration | Output current exceeded acceleration threshold during speed ramp-up. | Acceleration time set too short, excessive mechanical load inertia, incorrect motor parameter configuration. | Increase acceleration time, check motor data and current limit parameters. |
| OC5 | Inverter I x t overload | Thermal load accumulator (I x t) reached maximum limit due to continuous overcurrent. | Drive operated above rated continuous current for an extended period. | Reduce mechanical load, optimize duty cycle, verify servo drive sizing. |
| CE0 | System Bus (CAN) communication fault | Communication failure or time-out detected on System Bus (CAN). | Interrupted CAN bus line, missing termination resistor, bad baud rate setting or excessive electrical noise. | Verify CAN cable connection, bus termination (120 Ohm), shield grounding, and node address settings. |
| EER | EEPROM data error | Checksum fault detected during read/write access to non-volatile parameter memory. | Power interrupted during parameter saving, defective EEPROM chip. | Reload factory default parameters and write to EEPROM. If error reoccurs, internal hardware fault — return unit for repair. |
| H05 | Internal hardware failure | Power section or control card hardware fault detected during self-test routines. | Component failure on internal control board or gate driver board. | Internal hardware fault — field repair not possible. Return unit for repair or replace drive. |
| NMAX | Speed limit exceeded | Actual motor velocity exceeded maximum configured speed limit threshold. | Unstable velocity loop tuning, incorrect feedback scaling, runaway load condition. | Check feedback encoder/resolver connections and speed controller gain settings. |
| Sd2 | Resolver signal fault | Resolver signal loss or track error detected at terminal X7. | Broken or disconnected resolver cable, damaged connector pins at X7, bad cable shielding. | Check resolver feedback cable wiring, shielding integrity, and connector tight fit at X7. |
