The Sanyo Denki PV Servo Systems with SERCOS are fully-digital, extremely compact and offer both high-performance and a rich set of features. The only connection from the controller to the PV Series drives is the SERCOS fibre optic cable.
The AC servo drives have complete built-in functionality including high-speed registration inputs, dynamic braking and handling of regenerative energy. Extra regeneration energy handling capability can be added to each PV Series servo drive with standard external regeneration resistors.
All drive parameters can be accessed with AML using the SERCOS identification numbers (IDN´s). Standard cables for motor power and encoder feedback are available that have all the necessary connections made on both ends of the cables.
There is also an optional breakout board with screw terminals and a connection cable to facilitate the I/O connections to the servo drive.
A total of 7 compact PV system combinations are currently available:
A selection chart is also available to help you choose a system. Remember that the standard size PE Systems with SERCOS are also available - up to 5kW.
All the motors operate to a maximum speed of 4500 rpm except the medium inertia 1500W (P6) motor which has a max speed of 3000 rpm. All motors have a built-in 2000 line (8000 count per revolution) encoder and optional 24 VDC spring-set holding brakes.
The PV Servo System with SERCOS is a digital solution with fine interpolation, position loop, velocity loop, and current loop within the drive. The SERCOS interface is designed to communicate real-time control data for high performance motion control. For example, each position command in a 16-axis control system can be updated 500 times in one second using SERCOS (at 4 Mbits/sec data rate). However, the position command update time should not be confused with the servo loop update rates. The PV Series servo drive internally extrapolates the position command and updates the position loop 4,000 times each second. The velocity loop is also updated 4,000 times each second while the current loop is updated 16,000 times each second!
Sanyo Denki SERCOS compatible servo systems are suitable for a broad range of applications including: Packaging, Converting, Winding, Injection Molding, Printing, Metal Forming, Material Handling, Web Handling, and most other types of general purpose industrial machine control.
