Description
The Lenze EVS9321-ES (EVS932x-ES) is a high-performance servo inverter / servo drive from the Lenze 9300 / 9400 Top Performance series (often referenced as the 9300 book-style drive with ES = Encoder Simulation / Standard version). It is designed to control synchronous servo motors (MCS series) and asynchronous vector motors (MDx series) with precise speed, torque, and position control via onboard motion tasks or higher-level PLC/CNC.
Listed models EVS9321 / EVS9322 / EVS9323 / EVS9324 / EVS9325 / EVS9326 / EVS9327 / EVS9328-ES represent power range coverage from 0.37 kW (9321) up to 75 kW (9328) — all sharing the same control architecture, parameter set, and communication options (CANopen, PROFIBUS DP, EtherCAT, POWERLINK — depending on installed option board).
Key Features
- Power Range: 0.37 kW (EVS9321-ES) → 75 kW (EVS9328-ES), 3 × 400/480V AC input.
- Control Modes: Speed control (V/f, VECTOR), Torque control, Positioning (internal 16-step positioning or via Tech Modules).
- Feedback Support: Resolver, Incremental Encoder (TTL/HTL/RS422), SinCos (EnDat 2.1/2.2, Hiperface — with option card), Absolute Encoder (SSI, EnDat — with card).
- Motion Logic: Integrated “Motion Function Blocks” — stand-alone positioning without external CNC.
- Communication: Built-in RS-232/485; slots for CANopen, PROFIBUS DP, EtherCAT, POWERLINK, PROFINET.
- Country of Origin: Germany
Model & Power Rating Table (EVS932x-ES Series)
Model | Rated Power (kW) @ 400V | Rated Current (A) | Matching Lenze Motor (Typical) |
|---|---|---|---|
EVS9321-ES | 0.37 kW | ~ 1.2 A | MCS 06, MCA 08 |
EVS9322-ES | 0.75 kW | ~ 2.1 A | MCS 09, MCA 11 |
EVS9323-ES | 1.5 kW | ~ 3.6 A | MCS 12, MCA 14 |
EVS9324-ES | 3.0 kW | ~ 6.5 A | MCS 14, MCA 17 |
EVS9325-ES | 5.5 kW | ~ 11 A | MCS 19, MCA 22 |
EVS9326-ES | 11 kW | ~ 21 A | MCS 25, MCA 30 |
EVS9327-ES | 22 kW | ~ 38 A | MCS 30, MCA 40 |
EVS9328-ES | 37 / 75 kW* | ~ 65 / 130 A | MCS 40+, MCA 50+ |
*EVS9328 covers both 37 kW & 75 kW frames — verify exact suffix (EVS9328-ES vs EVS9328-EK etc.)
⚠️ Important Notes:
Option Cards Required for Some Feedback: Basic unit supports resolver & incremental encoder; EnDat / Hiperface / SSI need EBxxx feedback option card. Control Voltage: 24 V DC (terminal X30) for logic & enable; Main power = 3× 400/480V AC (+10%/-15%). Brake Chopper / Braking Resistor: Built-in brake chopper on most models — connect external LZB braking resistor for regenerative applications. ES vs EK Suffix: “-ES” = Standard version; “-EK” may indicate “Compact” or different I/O population — verify compatibility with existing system. Software: Configure via Lenze Drive Studio / L-force Engineer — parameter backup strongly recommended before swap.
