Direct drives PSD

The growth of individualisation in the packaging industry is leading to ever smaller batch sizes. Moreover, customer wishes and specifications are creating challenges that require flexible machine solutions. Positioning systems automate format changes in machines with minimal changeover times and high repeatability. This dramatically reduces production downtime. With more than 25 years of experience in integrated drives, halstrup-walcher is a specialist in positioning systems for format changeover in machines.

To provide optimum support for machine builders, halstrup-walcher has developed a flexible modular system with a wide range of variants. This allows each application to be equipped with the correct drive. In its intelligent drives, the motor, motor control unit, bus communication and an absolute measuring system without battery are already integrated. These are complemented by a variety of monitoring, control and feedback functions. The PSx 3-series, which has been established on the market for many years, is based on durable and robust EC motors. The electric drives can also be provided with an NRTL certificate, which means they are certified compliant with UL, CSA and ANSI testing standards in the United States and Canada. The PSD product range uses stepper motors, which can also be used without gears and achieve higher speeds.

The hollow shaft allows the drives from both these product ranges to be mounted on the spindle without a coupling. This makes it extremely simple to upgrade machines by automating systems that previously relied on handwheels for format changeover. A range of modules are available to allow the customer to select the appropriate IP protection class for their application. With torques of 1.. 25 Nm, the compact drives can even adjust larger masses, supported by gearboxes integrated into the drive and the appropriate spindle pitch. The positioning systems have interfaces with all common buses, including IO-Link, to ensure easy integration into machine control systems. The manufacturer offers various description files and function modules for this purpose. halstrup-walcher’s extensive product portfolio offers machine builders the tools they need to meet the challenges of flexible machine design – both today and in the future.

Economically reduce set-up times: Positioning systems with intelligent PSxHub

halstrup-walcher has developed the intelligent PSxHub to implement the parallel operation of positioning systems for format adjustment as efficiently as possible: As an active bus component, the
smart connection element offers simple integration for up to 16 positioning systems from the PSD
family (PSD 4xx with IO-Link), ensures smooth communication with the controller and is economical
thanks to the single-cable solution with unshielded, standard A-coded cables, among other things.

The flexibly configurable synchronization control and monitoring integrated in the PSxHub ensures
synchronized parallel operation of the controlled positioning systems. As a flexible technology platform, the PSxHub enables a wider performance spectrum (e.g. in terms of power requirements
and synchronization) compared to classic IO-Link hubs without a control function. With its compact
housing design from 14.2 x 16.4 x 6.4 cm (control cabinet version), it is an efficient and space-saving
solution for central data and power transmission. The PSxHub is available for the Industrial Ethernet
systems PROFINET and EtherCAT (others on request).

Your advantages with the PSxHub:

• Simplified and cost-effective cabling
• Reduced effort for installation and initial start-up
• No tilting during parallel operation of several positioning systems thanks to optimum
  synchronization control in the hub
• Relief for the control system and machine bus
• Simple self-diagnosis and identification of the drives in the machine environment
• Fixed configuration of the hub enables simple modularization of machine components
