Lenze Inverters Control Alpine Ski Simulator
Two compact Lenze SMV frequency inverters are being used to provide smooth-start optimisation and motion control on the Whizzard Pro alpine ski simulator. The Whizzard Pro is designed both as a trainer for competitive downhillers and as an improvement aid for recreational skiers. The simulator, developed in Poland, is designed to take up minimum space, while providing the original experience of real skiing in the gym. Suitable for both skiers and snowboarders, the Whizzard Pro adjusts the slope angle while running and can provide experience of extreme conditions, even moguls, at speeds of up to 30km/hr.
Key to the realistic operation of the Whizzard Pro are two Lenze SMV inverters. The first of these, a 5.5kW unit, drives two motors that control the main track of the simulator. Controlled via a human-machine interface, this inverter was chosen for its low-speed operation, ease of use and compact dimensions, which enabled it to be integrated into the optimised envelope of the Whizzard Pro without modifications to the simulator structure. Low-speed operation is equally important on the second Lenze SMV inverter - a 2.2kW unit that controls the motor used to generate vertical movement on the Whizzard Pro, effectively simulating the irregularities experienced in downhill skiing.
The combination of the Lenze inverters is said to simplify the adaptation of vertical and horizontal speed on the Whizzard Pro, taking into account the skill level of the skier. The precise control provided also allows the simulator to be used for the rehabilitation of skiers following accidents and is claimed to offer a realistic element to complement existing ski training programmes. The SMV is suitable for simulation tasks, thanks to its simple control and setup procedures, which can be completed in seconds, and its programmable EPM chip.
The EPM allows users to copy across, in a matter of seconds, an entire operating set of parameters to another SMV drive. This same functionality can be used to change a set of simulation parameters in an existing drive, delivering a new experience to the simulator user. The EPM can often be used to return a machine to service without having to call out a support engineer or commit skilled programming time to re-commission an individual drive. The SMV range of inverter drives is available for single-phase operation from 0.37kW to 2.2kW and three-phase operation from 0.37kW to 22.0kW.
The SMV range removes the cost and complexity from vector-based motor control, offering fast dynamic torque response, sophisticated auto-tuning and excellent low-speed operation from a compact, low-cost package, according to Lenze. In addition, the SMV drive offers ingress protection to IP65, enabling its use outdoors, in environments with atmospheric moisture, and providing protection from low-pressure water jets. The SMV range is designed for use in motor applications where dynamic speed and torque control are required, such as conveyors, food production, packaging lines and heating, ventilation and air-conditioning (HVAC) systems.
