EVS9323-CRV003 Lenze 9300 Servo Inverter – Cold-Plate, 1.5 kW, Multi-Encoder, Fast Ship

EVS9323-CRV003 – Lenze 9300 Servo Inverter, Cold-Plate Design

Model EVS9323-CRV003 is a servo inverter from the Lenze Global Drive 9300 series. This is the cold-plate variant with software version V003. It uses field-oriented servo control for synchronous and asynchronous motors. The rear flat surface mounts to a cooling plate. This saves cabinet space and removes the need for internal fans. The unit suits compact, high-precision axis systems.

Expert Review

The EVS9323-CRV003 solves a real cabinet problem. The cold-plate design moves heat outside the enclosure. You get precise servo control without a built-in fan. The multi-encoder input accepts TTL, SinCos, and Hiperface devices. This makes it flexible for retrofits. The 1.5 kW size fits small axis modules. For new builds, check the i950 path. For existing 9300 systems, this is a smart spare.

Manager’s Insight

This unit is ideal when space is tight. The cold-plate rear mounts to a machine frame or heat sink. You save cabinet depth (158 mm versus 250 mm). The AIF slot lets you add PROFIBUS or DeviceNet later. The CANopen bus is already built in. Stock is limited because the 9300 series is legacy. Secure units early for critical servo axes.

Best Suited Devices and Applications

• Compact servo axes – precise positioning in tight cabinets
• Machine tools – field-oriented control for smooth motion
• Packaging machinery – fast response with resolver feedback
• Textile and printing lines – stable speed with encoder input
• Legacy 9300 servo systems – direct spare for existing cabinets

FAQ

Q: What is the difference between the cold-plate and built-in design?

A: The cold-plate variant has a flat rear surface. It mounts to an external heat sink. The built-in design has its own fan and is deeper (250 mm versus 158 mm).

Q: Which motors can this inverter drive?

A: It drives synchronous servo motors, asynchronous servo motors, and standard asynchronous motors. The field-oriented servo control mode handles all three.

Q: Does the unit include a fieldbus as standard?

A: CANopen is built in on the CAN system bus. Other fieldbuses need a pluggable AIF module – PROFIBUS DP, DeviceNet, INTERBUS, or LECOM A/B.

Q: What is the warranty and dispatch time?

A: We provide a 12-month warranty. Orders ship within 12–24 hours using FedEx, UPS, or DHL.

Q: Is UL approval available?

A: No. The official data states this model is not UL-approved. Check your local code requirements before installation.

Buying Guide

• Confirm motor type: Check if you use a synchronous servo, async servo, or standard async motor.
• Check feedback device: Resolver, TTL, SinCos, or Hiperface – the multi-encoder input covers all.
• Plan cooling: The cold plate needs a flat heat sink or machine frame surface. Clean and flat is best.
• Choose fieldbus: Order the AIF module you need. CANopen works without extra hardware.
• Order spare early: Legacy stock is limited. Fast dispatch in 12–24 hours helps critical lines.

Packaging and Warranty

• Packaging list: Servo inverter unit, terminal covers, documentation (digital copy available).
• Warranty: 12 months from delivery.
• Dispatch: 12–24 hours after order confirmation.
• Couriers: FedEx, UPS, DHL.
