Controller offers the best of both worlds

Controller offers the best of both worlds
A new compact controller from Lenze combines PLC logic with motion control, meeting the needs of multi-axis machinery.

Designed for centralised control systems, the new Lenze 3200C controller combines PLC logic, motion control and visualisation in a single device. This completely new design is targeted at complex machines with multiple axes and centralised control such as packaging machinery, handling systems and robots.

By bringing together the latest fast microprocessors with updated operating software, the 3200C delivers a tailored hardware-software combination that can implement automation systems in a cost-effective way. This new controller suits machines with single-and multi-axis drives giving powerful centralised control over a matching range of external drives and actuators. Dimensions are compact with DIN rail mounting and a width of only 136mm, and reliability is assured as there is no fan or battery. 

The 3200C controller is designed to integrate with the Lenze I/O system 1000 creating a single station with a fast 48MHz backplane bus and a 1µs time stamp. Individual I/O modules can be added directly as elements in the structure of the project tree in PLC Designer - and the backplane bus of the I/O system is seamlessly integrated into the engineering environment. Dedicated user interfaces are provided for setting the I/O parameters. Thus the I/O System 1000 integrates with the 3200C controllers both mechanically and in programming software. Creation of a single customised station with controller and I/O saves project time.

Flexible I/O configurations
Up to 64 I/O modules can be combined with digital and analogue I/O, temperature measurement, counters and encoder evaluation. Communication ports are provided for Ethernet and the fast bus EtherCAT which can connect to servo and inverter drives, also external I/O stations. Two further ports are provided on the controller for CANopen and optional PROFIBUS.

Two USB connections are available and there is an optional third USB for DVI connections to a monitor panel such as the Lenze MP range. These touch screen panels extend from 10 to 19 inch and can be either panel mounted into the machine or separately mounted as an IP65 command station. Should the controller and monitor be located more than 5m apart, distances up to 40m can be bridged using a DVI/USB extender. This gives great flexibility in designing systems where the controller acts as the hardware for the visualisation. 

Project planning is simplified by the latest software. The 3200C operates with Windows CE 6.0 and is provided with Lenze PLC Designer software which enables programming to the languages of IEC61131-3. This latest version of PLC Designer is based on the CoDeSys3 programming system which has been tailored and optimised for the controller. Programming of motion functions is to PLCopen standards. Designers can use the new controller as a gateway, for example evaluating PROFIBUS signals and transmitting them in Ethernet. 

The PLCopen library includes modules that can be used to program and implement motion in individual axes as well as synchronised movement in multiple axes. Library components include modules for parameter setting and function blocks for the speed and acceleration profiles required. For example, the specification could take the form of a cam profile generated in PLC Designer. The scope of supply also includes function blocks for programming electronics gearboxes or for phase adjustment. 

For the machine designers wanting to reduce project planning time, the Lenze 3200C scores by bringing together PLC logic, motion control of drives, and visualisation. Further savings come from the integration of I/O into a single DIN rail mounted station and the Lenze portfolio of matching inverter drives, servo drives and monitor panels. PLC programming with the latest CoDeSys3 is faster and reduces cost. Complete automation systems can be implemented efficiently through the controller. 

The 3200C controller is designed for 'motion centric automation' - that is, machines where rotary and linear movement are an essential part of the function. Typical are complex machines for packaging, printing, handling systems and robots which require a powerful and uniform automation system with centralised control. The 3200C enables the coordinated movement of multiple axes and is also able to assume the control functions of a line process.
