Flexible Drive Design
An innovative drive design allows flexible to drive architectures: a multi-axis system, in which single and dual-axis servo drives are connected to a shared power supply, reduces costs and space requirements in systems with more than four servo axes.  Pluggable interconnects and a quick-connect front-side bus also reduce installation costs.

The servo drives of the Lexium 62 series are consisting of:

• Single (1 axis) and Double (2 axes) drives, Standard type,
• Single (1 axis) and Double (2 axes) drives, Standard type with embedded safety
• Single (1 axis) drives, Advanced type: delivered with second encoder input and an incremental encoder output interface,
• Power supplies,
• and as an option, DC Link support module with DC Link terminal.
  The single and double drives in a group use a shared power supply. Multiple groups are possible, with the number of axes being limited by the type of controller used.

The Lexium SH3, MH3, and the SHS stainless steel servo motors form the basis for servo solutions with Lexium 62 and cover a wide range of performance and flange sizes. All motors are equipped with electronic nameplates, which is making them an integral component of the PacDrive 3 automation system.

Specifics of the Lexium 62 multi-axis drive system

• Less space required in the control cabinet
• Minimal assembly/installation time
• Optimized feedback loops minimize contouring errors
• Embedded safety on drives with STO, SS1, SOS, SS2, SMS, SLS, SDI (according to IEC 61508, EN/ISO13849-1)
• Automatic motor detection
• DC Link connection – combines benefits of the multi-axis drive with flexibility of standalone drives

Fast Connection
The Lexium 62 components offer easy handling and installation, startup, and replacement: the quick front-side connection to the power supply automatically includes integration into the DC bus as well.

Motor and encoder connection
Motor/encoder cables exit at the bottom of the unit: this leaves the room at the front of the device for rapid assembly/disassembly of Lexium 62 components.

Connection to the Sercos ring via Sercos interface module
The Sercos ring can be connected quickly via the Sercos interface on the power module and the drive modules. Single and double drives are integrated into the Sercos ring with short cable bridges.

Connection to DC bus
The servo drives are coupled at the front side: no backplane connections are required.  A module can be coupled to the adjacent modules in less than two minutes, using a quick front-side connection with locking screws. When the connection is made, LEDs indicate the correct power supply with the 24 V control voltage.  The DC bus can provide a 120 A continuous current (maximum). The servo drives have an electronic type plate. Upon first use or exchange of the device, it is identified by the centralized controller and configured based upon the specified parameters. The servo drives themselves, in turn, detect connected motors by their type plates.
To connect to the DC bus, 24 V power supply, and ground wire: move the slider to the left and tighten the screws.

• Flexible Connection
• The main component is the DC Link terminal: it is mandatory to create DC-Link connections.
• The DC Link: DC link connection module is an auxiliary module required for some configurations, e.g. cable length > 3 m. It allows us to connect Lexium 62 devices in a single cabinet or to connect Lexium 62 devices distributed over several cabinets, with an easy and fast connection thanks to the DC Link terminal which can be mounted on each Lexium 62 servo drive or power supply. The DC Link terminal can be mounted to both sides of Lexium 62 devices.
• Line and star topologies supported
