LA700

AC drives for lift applications

Does your lift need a new drive?

We have the perfect fit. Our LA700 lift drive comes with integrated safety features, highest ride comfort and outstanding reliability. Installing LA700 to your lift adds sustainability while saving you time and energy.

Simplified system integration

LA700 drives are designed to be easily integrated into lift systems. Embedded safety functions, integrated filters and braking choppers reduce the number of components in the control panel, which does not only reduce the space required but also increases system reliability.

Fast installation and setup

A highly flexible interface allows easy integration with most any lift controller. Easy wiring and smart functions for completing a basic setup in a couple of minutes minimize the time and cost involved in the commissioning of your lift.

Highest ride comfort

With precise motor control and high starting torque, flexibly configurable ride curves and integrated brake control logic, the LA700 provides the key to a smooth ride and accurate landing.

Sustainable systems

Designed for 10 years of operation without maintenance, our LA700 drives are built to perform reliably for a long time. The robust design featuring coated PCBs allows operation in 50 °C without derating, while integrated service lifetime prediction prevents sudden failures and downtime.

The power to lift!

Key features and benefits

Designed to drive both induction and permanent magnet motors, LA700 drives are becoming the preferred choice for various applications, including new installations, machine-room-less lifts and modernisation projects. By choosing an LA700 drive, you can experience our proven reliability with a higher standard of ride comfort, ensuring a modern and efficient solution for today's lift systems.

Super-smooth ride comfort

Ride profiles with individual jerk setting for each speed change and different selectable acceleration/deceleration ramps allow fine tuning for a smooth and shockless ride.

  • Five individual jerk settings for each speed change.
  • Up 4 to different selectable acceleration/deceleration ramps.
  • Dedicated and easy to adjust lift brake sequence.
  • Three independent Speed Loop settings for fine tuning. (ASR) (Start/Constant/Stop)
  • Allows fine tuning for a smooth and comfortable ride.

Rescue & evacuation function

When the power fails and people need to be rescued, we have the new Advanced Light Load function. The LA700 will automatically evacuate in the direction of regeneration. This function allows the use of smaller UPS.  UPS or DC battery backup can be used.

UCM brake monitoring

The LA700 is available with brake monitoring as part of it's protection against unintentional car movement for UCM:EN 81-1:1998+A3:2009 9.11.3 and EN 81-20:2014 5.6.7.3.
This replaces external devices, reducing installation time and cost.

Anti-rollback feature + torque compensation as an option

For improved ride comfort, the starting torque when releasing the brake is set during commissioning.

  • Improved Anti-Rollback function for smooth starting
  • Torque compensation function also available with load cell.

Short floor function

The Short Floor function controls that the travel distance is reduced from the highest frequency or nominal speed to the levelling speed during deceleration. In all cases (positioning accuracy) is the same. This means that the lift travels different distances if the levelling speed command is set to different speeds.

  • Short floor operation is used when the fast speed is not reached between floors. 
  • It optimizes the leveling speed/distance of the lift and reduces the travelling time.

Lifetime monitoring & predictive maintenance

Monitor the life of your drive and minimise unplanned downtime.

  • Number of run commands
  • Drive and fan running time 
  • Capacitor, IGBT SoftCharger relay, 
  • Cooling fan life
  • Drive temperature
  • Drive, motor overload
  • Peak current  

LA700 – flexibility, ease of use, and a sustainable design offer the best value proposition for your lift application.

Relaxing in daily use and installation

Enjoy a smooth and comfortable ride of your lift. The excellent motor control of the the LA700 and the integrated brake control sequence guarantee for soft changes in speed and accurate landing.

Highest comfort

Ride profiles with individual jerk setting for each speed change and different selectable acceleration/deceleration ramps allow fine tuning for a smooth and shockless ride.

The accurate leveling control of LA700 makes floor and cabin ground even under any load condition, thus avoiding dangerous traps.

The flexible brake control sequence optimizes the start and stop for soft movement and accurate landing.

  • Adjustable speed profiles with individual jerk settings
  • Accurate leveling independent of load
  • Short floor management
  • Easy to tune brake sequence for smooth ride and best landing
  • Evacuation in light direction for smallest possible UPS/battery
  • Optional speed feedback option card for the connection of a TTL encoder

Makes life easy

The integrated EMC filter and braking chopper make installation faster, reduce wiring, save space and time. Intuitive menus with lift terminology (terms and units on LC display) simplify the setup procedure. Operate the lift without motor contactors - just make use of the Safe Torque Off function (STO, SIL3) of the LA700. Avoiding additional contactors also reduce the space required,
wiring effort and eliminates switching noise.

  • Integrated EMC filter with class C2 for EN12015 compliance
  • Integrated braking chopper
  • Integrated SIL3 STO function for operation without motor contactors
  • Flexible control sequence to work with almost any controller
  • Setup in lift terminology and units
  • Automatic motor data tuning in stand still condition without removing ropes

Sustainable

With it's innovative design the LA700 paves the way to sustainable lift system. The LA700 is designed with durability in mind. It can stand more than 2.5 million full load starts while components are selected to provide up to 10 years operation free of maintenance.

The drive's cooling fans are temperature controlled and only run when really required. This avoids pollution by twirling dust inside the panel, improves reliability, and minimizes the need for regular maintenance.

LA700 is not only reliable, it also helps to make your lift green. The very low stand-by power consumption of only approx. 10 W saves energy and helps to achieve Class 1 rating in terms of efficiency for your elevator (according to ISO 25745-2; max 50 W).

  • Long lasting design
  • Maintenance free
  • Energy saving by super low stand-by consumption
