Description
The Bosch Rexroth HMD01.1N-W0020-A-07-NNNN (R911295322) is a state-of-the-art DoubleAxis Inverter from the ctrlX DRIVE series, designed for high-efficiency control of dual motor operations. This inverter is engineered to convert supplied DC voltage into a regulated AC output with adjustable amplitude and frequency, accommodating the operational needs of two motors simultaneously. It operates by drawing power from the DC bus of XVE or XVR supply units and/or XCS or XCD converters. Equipped with a standard runtime that supports most drive tasks, this inverter also offers optional function packages for more complex applications. The hardware can be enhanced with ctrlX SAFETY options to cater to safety-related applications up to SIL standards, providing flexibility and assurance in demanding environments. The HMD01.1N-W0020-A-07-NNNN allows for the free selection of motor encoders, including the possibility of integrating a second encoder through its optional multi-encoder interface compatible with various technologies such as Resolver, AcuroLink, Hiperface, EnDat., and SSI. Its integrated safety technology streamlines processes while ensuring compliance with rigorous safety protocols. Notable for its space-saving design, this double-axis converter offers scalable power ranging from x1 to x4 A_subpeak_, conforming to EMC environment EN standards. The device dimensions include a width of 50 mm and a height that accommodates typical motor ratings, with provisions for maximum current and continuous current specifications. It supports a switching frequency up to max output frequency kHz while maintaining an international protection code of IP20. Cooling is efficiently managed through an internal air cooling system within the robust structure that ensures long-term reliability and performance. The ctrlX configurator facilitates customization and setup according to specific user requirements. With reduced wiring needs due to single-cable technology compatible with MSN synchronous servo motors and support for cable lengths up to 100 meters without additional components, installation is simplified and streamlined. Overall, the Bosch Rexroth HMD01.1N-W0020-A-07-NNNN inverter represents advanced engineering for precise motion control in various applications requiring dual-axis drive solutions.
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)
