Lenze automation systems have supported industrial manufacturing, material handling, packaging, intralogistics, conveyor systems and machine automation for decades. Many Lenze drive systems, motion control products and automation components continue operating reliably long after specific product families have reached mature, discontinued or legacy status.
For maintenance engineers and procurement teams, maintaining an existing Lenze automation system is often more practical than replacing an entire machine or control architecture. In many situations, sourcing compatible legacy Lenze automation parts helps extend equipment life, minimise downtime and preserve proven production systems.
This guide explores the major legacy Lenze automation product families, including servo drives, frequency inverters, PLCs, industrial controllers, HMIs and supporting automation components, together with best practices for maintaining legacy Lenze equipment.

About Legacy Lenze Automation
Lenze has long been recognised for industrial drive technology, motion control systems and machine automation solutions. Its products are widely installed in conveyor systems, packaging machinery, production equipment, material handling systems, textile machinery and automated manufacturing facilities.
Many legacy Lenze systems remain in daily operation because they continue delivering reliable performance and are deeply integrated into existing machine designs. Replacing an entire drive or control system may require significant engineering work, software updates, electrical modifications and production downtime.
Maintaining these systems often depends on sourcing compatible legacy Lenze automation parts rather than replacing complete automation platforms.
Understanding Lenze Product Lifecycle
Like all industrial automation equipment, Lenze products move through lifecycle stages as technology evolves and newer product families replace earlier generations.
| Lifecycle Stage | Description | Typical Maintenance Action |
|---|---|---|
| Active | Current production equipment. | Standard procurement. |
| Mature | Still widely installed but approaching replacement. | Begin spare parts planning. |
| End of Sale | Production has ended. | Evaluate legacy sourcing options. |
| Obsolete | No longer manufactured. | Source through obsolete automation specialists. |
| Legacy | Still operating in industrial environments. | Maintain through planned lifecycle management. |
Why Lenze Parts Become Legacy
Lenze automation products become legacy as newer technologies, processors, communication standards and drive systems are introduced.
Technology Development
Drive electronics, motion control and automation technologies continue evolving.
Electronic Component Availability
Internal electronic assemblies may eventually become unavailable.
Automation Platform Updates
Older controllers and drives are gradually replaced by newer product families.
Machine Lifecycle
Many machines remain productive long after individual automation components become obsolete.
Legacy Lenze Drive Families
Lenze has produced several industrial drive families that remain widely installed throughout manufacturing environments.
| Product Family | Typical Applications | Legacy Status |
|---|---|---|
| 8200 Vector | General machine automation | Legacy |
| 9300 Servo | Servo motion control | Legacy |
| 8400 Series | Machine automation | Mature / Legacy |
| i500 Drives | Industrial motor control | Mixed active & mature installations |
8200 Vector Drives
8200 Vector drives remain widely installed in industrial machinery, conveyors and production systems where reliable motor control continues to support manufacturing operations.
9300 Servo Drives
9300 Servo systems are commonly used in applications requiring accurate positioning, synchronisation and motion control.
8400 Drive Series
The 8400 drive family continues supporting numerous machine automation applications where compatibility with existing equipment remains important.
Motion Control Systems
Lenze motion control products support coordinated machine movement, servo positioning and synchronised production processes. Legacy motion systems frequently depend on compatible servo drives, controllers, feedback devices and communication modules.
Replacing a single motion component without verifying compatibility may affect machine performance, commissioning and software configuration.
PLCs & Controllers
Lenze automation controllers are used to coordinate machine logic, drive systems, safety functions and industrial communication. Legacy controllers may continue operating for many years where machine performance remains satisfactory.
When replacing legacy controllers, hardware revision, firmware version, communication interfaces and software compatibility should always be verified.
Common Legacy Lenze Components
Servo Drives
Motion control and positioning systems.
Frequency Inverters
Variable speed motor control equipment.
Controllers
Machine automation controllers and PLCs.
Communication Modules
Industrial networking and fieldbus interfaces.
Power Supplies
Supporting controller and drive operation.
Operator Interfaces
Machine HMIs and operator panels.
