Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF9330-EVV004 is a panel-mounted frequency inverter from the 9300 Vector series, engineered for speed and torque control of three-phase AC motors in heavy-duty industrial applications. Operating from a supply voltage range of 400 V AC to 480 V AC (with operational supply limits between 320 V AC and 528 V AC), this drive delivers a continuous output current of 145 A and a rated input current of 140 A to support 75 kW motor loads. The inverter supports multiple control modes including V/f characteristic control, sensorless vector control, and closed-loop vector control with encoder feedback across an output frequency range of 0 to 480 Hz at a default 8 kHz switching frequency. Built as the V004 design variant, this unit is constructed without an internal RFI interference suppression filter, making it purpose-built for panel installations utilizing centralized EMC line filtering.
Integration into automated drive systems is provided by an onboard high-speed CAN system bus operating up to 500 kbit/s, alongside a 33-pin Automation Interface (AIF) slot. The AIF slot accepts expansion cards for fieldbus integration, including PROFIBUS-DP (EMF2133IB), CANopen (EMF2173IB), DeviceNet, and INTERBUS, or an RS232 LECOM-A adapter (EMF2101IB). Hardwired terminal interfaces include 5 digital inputs, 2 digital outputs, 2 analog inputs, and 2 analog outputs. Commissioning a replacement unit requires configuring parameters to match the motor and application settings, as up to four complete parameter sets can be stored in internal EEPROM memory. Parameter configuration and backup transfer can be performed using Lenze Global Drive Control (GDC) software or an optional XT Keypad (EMF2102IB). When replacing a faulty drive, extracting parameter sets directly from donor hardware with assistance from ABC Industrial Parts helps ensure correct parameters and bus addresses prior to restoring power.
Operational status and fault diagnostic feedback are provided via front-panel LEDs and status relay outputs on terminals K11, K12, and K14. The green READY LED blinks when the drive is ready and remains solid ON when the inverter is enabled and running, while the red TRIP LED remains solid during active fault conditions. Detailed diagnostic readouts and fault history codes stored in parameters C0168 and C0170 can be accessed via the XT Keypad or GDC diagnostic monitor. Common field trips include short circuits or overcurrent (OC1, OC2, OC5), DC bus voltage faults (OU, LU), heatsink and motor overtemperature (OH, OH3, OH4, OH7), phase failure (LP1), or fieldbus communications errors (CE0, CE1, CE2). Basic checks should verify input line voltages on L1, L2, L3, thermistor wiring on terminals T1 and T2, and 120 Ohm termination on CAN lines. When internal hardware faults such as H05 or system processor errors SYS occur, board-level failures cannot be serviced in the field, making tested exchange units or repair services through ABC Industrial Parts the most efficient path back to production.

Programming and Configuration
Configuring the Lenze EVF9330-EVV004 vector frequency inverter is performed using Lenze Global Drive Control (GDC) software or via the optional pluggable XT Keypad module (EMF2102IB). The drive incorporates internal EEPROM memory capable of holding up to four complete, independent parameter sets. This capability supports multi-mode operation or fast parameter set switching for specialized industrial tasks.
Parameterization defines motor parameters, control modes (V/f curve, sensorless vector, or closed-loop encoder control), ramp times, current limits, and fieldbus node parameters. Drive parameter sets stored in internal EEPROM can be saved, backed up, and uploaded using GDC software connected via a LECOM-A RS232 adapter (EMF2101IB) or directly transferred using the XT Keypad module.
Communication and System Integration
The EVF9330-EVV004 comes equipped with an integrated high-speed CAN system bus interface operating at bit rates up to 500 kbit/s. This system bus provides direct drive-to-drive cross-communication and synchronization in multi-axis machinery without placing additional load on higher-level fieldbus systems. Reliable CAN operation requires verified shielding, node address settings, and 120 Ohm termination resistors at both ends of the bus.
For integration into major fieldbus networks, the drive includes a 33-pin Automation Interface (AIF) slot. This interface supports option cards including PROFIBUS-DP (EMF2133IB), CANopen (EMF2173IB), DeviceNet, and INTERBUS modules. I/O connections feature 5 digital inputs, 2 digital outputs, 2 analog inputs, 2 analog outputs, and programmable status relays across terminals K11, K12, and K14.
Diagnostics and Status Indication
The drive provides continuous status and fault monitoring through front-panel LEDs, relay outputs, and internal status parameters. Physical relay outputs on terminals K11, K12, and K14 allow remote signaling of drive ready and trip conditions directly to a supervisory PLC interface.
Comprehensive diagnostic history can be evaluated using Lenze GDC software or the XT Keypad display. Current fault states and past trip history logs are recorded in parameters C0168 and C0170, enabling rapid identification of electrical, thermal, or communication issues.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (TRIP) | Red - Solid | Active drive fault / Trip condition present |
| Green LED (READY) | Green - Blinking / Solid | Blinking: Drive ready for operation; Solid ON: Inverter enabled and running |
Replacement and Spare Part Considerations
When selecting a replacement for the EVF9330-EVV004, ensure the V004 variant code is specifically matched. Because the V004 variant is manufactured without internal RFI suppression filtering, installing this drive into a cabinet without central EMC line filters will lead to non-compliance with noise emission standards and potential interference issues.
A replacement drive cannot be operated immediately out of the box without transferring configuration parameters. Before connecting to power and motor terminals, transfer all parameter sets stored in the internal EEPROM from the existing unit using Lenze GDC software or the XT Keypad module. Ensure motor control settings, encoder feedback configurations, and network settings (such as CAN node address or PROFIBUS slave addresses) are verified prior to commissioning.
