CLDP Servo Drives – CLDP Linear Drives

CLDP servo drives are linear drives with hydraulic power transmission. This makes the drives nearly wear-free and gives them unlimited overload protection. They fea­ture compact design and an integrated closed-loop hydraulic system. The servo drives have only a few electrical interfaces. No knowledge of hydraulics is required for installation and commissioning.

CLDP linear drives have been standardized. The large number of designs and sizes allows you to make a quick and ideal choice for your application. Time and effort for engineering the drive itself are unnecessary. Applications include almost any linear motion requiring high dynamics and precision.

Advantages and benefits

Features Advantages Benefits
  • Servo drive with hydraulic power transmission.
  • The drive is wear-resistant and absolutely overload-safe.
  • Your drive components and moving parts have a long lifetime.
  • After an overload occurs, your machine or equipment can be quickly and easily restarted.
  • The drive has only a few electrical interfaces.
  • This keeps your startup effort and costs low.
  • Personnel with knowledge of hydraulics is not required.
  • Closed-loop hydraulic system with no directional control valves or servo valves.
  • The integrated hydraulic system is a stand-alone system (self-contained).
  • You save the procurement and maintenance costs required for an external hydraulic power pack with all of its piping and tubing.
  • The linear drive is easy and cost-effective to install in machines and equipment.
  • The hydraulic cylinder is controlled with a servo pump whose flow rate is matched to the cylinder sur­faces.
  • Simple and compact design with no classic valve and control technology.
  • The linear drive requires up to 50% less energy, reducing your operational costs.
  • The costs for commissioning, training, and maintenance are low.
  • Hydraulic system throttle losses are kept to a minimum.
  • The drive is energy-efficient and has low cooling requirements.
  • Standardized linear drive with very few components and modular design.
  • This keeps planning costs associ­ated with system integration low.
  • A large number of designs and sizes are available.
  • This reduces development times and development costs asso­ci­ated with your machinery or equipment.
