Lenze 9300
The Lenze 9300 series was a versatile line of intelligent frequency inverters and servo drives, highly regarded for their use in complex and modular machine applications. These drives were designed to independently control machine sub-processes, reducing the load on a central PLC (Programmable Logic Controller).
Key Features and Specifications
The 9300 series was modular, supporting both basic frequency control and high-precision servo applications.
| Feature Detail | |
| Product Type | Frequency Inverter & Servo Drive |
| Control Method | V/f control, vector control, and highly precise servo control with feedback (e.g., SinCos encoders or resolvers). |
| Power Range | 0.37 kW to 90 kW (frequency inverters); 0.37 kW to 75 kW (servo inverters). |
| Input Voltage | 400 V or 480 V (three-phase), with some models supporting 500 V. |
| Overload Capacity | Up to 180% of rated torque for 60 seconds. |
| I/O | Configurable digital and analog s/outputs, including an for an external supply to the control electronics during mains failure. |
| Communication | Pluggable function modules for integration into common fieldbus systems such as PROFIBUS, CANopen, INTERBUS, and POWERLINK. |
| Safety Features | Available with an integrated "Safe Torque Off (STO)" function for safety compliance. |
Variants
The series came in several versions tailored to specific applications:
- 9300 Vector: Frequency inverters for complex applications like dosing, winding, pumps, and fans.
- 9300 Servo: Versatile servo inverters with functions like electronic gearing for synchronized operation.
- 9300 Servo PLC: Servo inverters with an integrated PLC, freely programmable in IEC 61131-3 languages, for highly integrated, intelligent drive solutions.
- 9300 Position Control: Inverters designed for precise positioning, used in robotics and material handling.
- 9300 Cam Profiler: Designed to store multiple electronic cam profiles, allowing for quick profile switching during production.
Current Status and Replacements
The Lenze 9300 series has reached its end-of-life status and is no longer being manufactured by Lenze. The discontinuation was partially due to regulatory changes (RoHS directive).
- Migration: Lenze recommends that customers using 9300 series drives migrate to its modern i500 series inverters for current requirements.
- Support: Spare parts are limited and increasingly difficult to source directly from the OEM, though third-party specialists offer repair and replacement parts
