Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13432636 EVF9326-EV is a 15 kW frequency inverter from the 9300 Vector series designed for precise AC induction motor control in industrial automated machinery. Operating on a three-phase nominal supply voltage of 400 V AC or 480 V AC across an operational input range of 320 to 528 V AC, this IP20-rated drive supplies a continuous output current of 32 A at 400 V and 27 A at 480 V. It provides accurate velocity and dynamic torque regulation across an output frequency range of 0 to 480 Hz with an 8 kHz switching frequency using either field-oriented vector control or customizable V/f characteristic control. Integrated function blocks support internal PID process loops, logic functions, programmable acceleration ramps, and brake chopper control.
For system connectivity, the unit includes an onboard CANopen system bus operating at up to 500 kbit/s for inter-drive networking, alongside a front Automation Interface Slot (AIF) that accepts plug-in fieldbus communication modules such as PROFIBUS-DP (EMF2133IB), DeviceNet (EMF2173IB), and INTERBUS (EMF2113IB). Commissioning a replacement spare requires transferring device settings, as drives are rarely ready to run straight out of the box. Up to four parameter sets can be stored in non-volatile internal memory and uploaded or downloaded using Lenze Global Drive Control (GDC) software v4.x or v5.x, or copied directly using an optional XT Keypad Module (EMF2102IB). ABC Industrial Parts can assist maintenance teams with pre-configuring replacement units and backing up application parameters to ensure smooth installation.
Operational status and active faults are indicated via front status LEDs, where a solid green light signals readiness, a flashing green light shows operation suppressed or drive inhibited, and a red light indicates an active TRIP condition. In-depth diagnostics are accessible via code C0059 for current TRIP status and code C0168 for the internal fault history buffer, viewable through the XT Keypad or GDC oscilloscope and diagnostic tools. Errors such as overcurrent (OC1, OC2, OC5), overvoltage (OU), undervoltage (LU), or overtemperature (OH, OH4, OH7) can often be resolved by verifying field wiring, motor insulation, line fuses, or cooling arrangements. When diagnostic codes such as H05 or EER indicate unrecoverable microcontroller, EEPROM, or internal output stage failures, field repair is not possible, making a tested replacement drive or specialized repair service through ABC Industrial Parts the quickest route to restore production.

Programming and Configuration
Programming and parameter setup for the Lenze 13432636 EVF9326-EV frequency inverter is carried out using Lenze Global Drive Control (GDC) software version 4.x or 5.x, or locally via the EMF2102IB XT Keypad Module. The drive features non-volatile internal storage capable of holding up to four complete, independent parameter sets, allowing versatile operational profiles for complex machines.
Parameter sets can be transferred between drives by copying data directly to the XT Keypad or uploading and downloading parameter files using GDC software. Key codes are utilized for quick drive management, such as code C0002 to execute a factory default reset or code C0011 to set the maximum motor speed limit.
Communication and System Integration
The EVF9326-EV incorporates an onboard system bus based on CANopen, providing high-speed drive-to-drive communication and multi-axis synchronization at data rates up to 500 kbit/s. Proper network operation requires correct line termination with 120 Ohm resistors at both ends of the CAN bus and matched baud rate settings across all connected nodes.
A front-facing Automation Interface Slot (AIF) allows modular expansion into higher-level fieldbus networks. By installing option cards such as the EMF2133IB for PROFIBUS-DP, EMF2173IB for DeviceNet, or EMF2113IB for INTERBUS, the drive integrates seamlessly into automated control architectures and PLC systems.
Diagnostics and Status Indication
The drive provides real-time operational state tracking and diagnostic tools through status LEDs and internal memory monitors. Current fault states are logged under parameter code C0059, while historic fault events are preserved in the internal history buffer under code C0168.
Maintenance technicians can perform live monitoring, trace system variables, and review fault logs using the GDC software diagnostic window and oscilloscope functions or directly via the XT Keypad module display.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready | Green - Solid | Inverter ready for operation |
| Ready | Green - Flashing | Drive inhibited or operation suppressed |
| Fault | Red - Solid or Flashing | TRIP or fault message active |
Replacement and Spare Part Considerations
When replacing an existing 13432636 EVF9326-EV inverter in an operational line, it is essential to ensure exact part number matching and parameter alignment. The replacement unit must be loaded with the active parameter set from the original drive using GDC software or an EMF2102IB XT Keypad module before enabling motor output.
In addition to parameter set transfer, any installed plug-in communication card (such as PROFIBUS-DP or DeviceNet) must be transferred to the new drive's AIF slot, and network address settings and baud rates verified. Check that motor thermal protection wiring (PTC on terminals T1/T2), line protection fuses, and external braking resistors are properly connected prior to commissioning.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short Circuit / Ground Fault | Short circuit or ground fault at output power terminals or motor windings. | Short circuit in motor cables or motor; ground fault; excessive ramp acceleration rate. | Check motor and wiring for short circuits and insulation faults; increase acceleration time; check drive output stage. If persistent without connected load, internal power stage is damaged and requires repair or drive replacement. |
| OC2 | Earth Fault | Earth/ground fault detected on motor phase leads. | Insulation failure in motor cable or motor winding; excessive capacitive charging current in long motor cables. | Check motor insulation resistance with megohmmeter; inspect cabling; verify maximum cable lengths. |
