Description
The CML40.2-SP-330-NA-NNNN-NW is control hardware from Bosch Rexroth. It is an IndraControl L40 that is supplied with a nominal value of 24 VDC. The unit complies with DIN EN 61131-2. It is tolerant between -15% / +20% when no residual ripple is present. The IndraControl L40 requires 3 operating voltages. The current consumption by ULS should never go over the maximum of 2.6 A. Current consumption by UM and the US should never go over the maximum of 8 A. combined. The unit is certified according to C22.2 No. 142-M1987 CSA and UL508. The CML40.2-SP-330-NA-NNNN-NW IndraControl L40 features a housing that is 75.9 mm deep, 120 mm high and 175.4 mm long. The unit features a display to the front with the operation made possible by 4 keys. The LCD features a 5 x 10 dot matrix resolution. There is also the reset button on the front along with a light-emitting diode just below the LCD. The unit can be used along with machine tools, packaging machines, foodstuff machines, assembly systems, handling systems, paper processing machines and printing machines.
The IndraControl L40 is a modular and scalable control. It combines the benefits of an embedded-PC architecture with a standardized I/O system with terminals. It is a universal hardware platform that can be used for motion-logic and PLC applications. The hardware is available in systemspecific versions (e.g. with/without SERCOS interface). It provides onboard interfaces, e.g. high-speed inputs and outputs (8 each) and communication interfaces, such as Ethernet, PROFIBUS, RS232 and SERCOS. Via the integrated PCI bus, additional modules permit extension of the IndraControl L40 by additional field-bus and technology interfaces, such as DeviceNet and master-axis-encoder interfaces. The locally available I/O units can be extended by the Rexroth Inline I/O system, just by simply mounting the components side by side. Application programs, incl. runtime, are completely stored to an easily accessible standardized Compact Flash medium. *Note: Compact Flash memory card and Firmware not included in the supply. Connector set for IndraControl L40 not included in the supply. Typical applications of the IndraLogic 40 are: • Handling and assembly systems • Packaging and foodstuff machine • Printing and paper processing machines • Machine tools The software "IndraWorks Logic" serves to commission and project the IndraLogic L40. It consists of the following components: • IndraWorks: Project planning, configuration • IndraLogic: PLC programming • IndraWorks HMI: Visualization and user interface as well as diagnostic functions (ProVi) • IndraWorks WinStudio: Engineering tool to create user screens for Software IndraWorks HMI • IndraLogic L40 TSP: Target files (Target Support Package) are installed required to edit the IndraLogic L40 with IndraWorks and IndraLogic.
The servo driver, also known as the servo amplifier or amplifier, is a device that outputs the pulse signal or analog signal input from the controller to the motor after internal calculation and amplification. Structure and principle The servo driver is composed of servo control unit, power drive unit and communication interface unit. The servo control unit includes position controller, speed controller, torque controller and current controller. The servo driver can be divided into two modules, the power board and the control board, which are relatively independent in function. The power board is the strong current part, which includes two units, one is the power drive unit IPM used to drive the motor, and the other is the switching power supply unit to provide digital and analog power for the entire system. The control board is the weak current part, the control core of the motor and the operating carrier of the core control algorithm of servo drive technology. The control board outputs PWM/PFM signal through the corresponding algorithm, which is used as the drive signal of the drive circuit to change the output power of the inverter, so as to achieve the purpose of controlling the AC servo motor.
Drive control mode
(1) PWM control (Shadik driver)
PWM control technology: control the on-off and off-off of semiconductor switching devices, so that the output end can get a series of pulses with equal amplitude and unequal width, and use these pulses to replace sine waves or other required waveforms. By modulating the width of each pulse according to certain rules, the output voltage of the inverter circuit can be changed, and the output frequency can be changed.
Advantages:
1) Low noise;
2) High efficiency at full load and can work in continuous conduction mode;
3) The ripple voltage is small;
4) The switching frequency is fixed, so the noise filter design is easier and the noise elimination is simpler;
5) The control method is easy to implement.
Cons:
1) Due to the influence of the error amplifier, PWM loop gain and response speed are limited, PFM has a fast response speed;
2) PWM is less efficient at low load.
3) PFM control (Panasonic Drive)
