Description
HDS02.2-W040N-HS12-01-FW by Rexroth, Indramat, Bosch is a Drive Controller in the HDS Series. The HDS02.2-W040N-HS12-01-FW features a Cooling Type of Air, internal (with built-in blower) and a Rated Current of 40 A. This Controller has a Version of 2 and comes with DIAX04 Controller Family. The HDS02.2-W040N-HD12-01-FW drive controller is used to control the motor’s position, speed, and torque. In addition to executing the servomechanism, the controller is used to drive a motor’s main spindle. With an IP 10 degree protection, the drive’s external enclosure is protected against objects that are larger than 50 mm in size. The required operational parameters are pre-programmed in the system. In case of error between actual and programmed values, the drive initiates the servomechanism and adjusts the values of the parameters. The drive controller has a standard configuration in which a basic unit, a command module, and a firmware module is provided. Because of the modular structure, the firmware module can be installed in any other drive controller. Since drive parameters can be stored in the firmware module, they can be instantly transferred to other drives by inserting the module in their software module slot. The HDS02.2-W040N-HD12-01-FW has a 40 A peak current. The drive supports various types of interface cards. Rexroth’s gear type encoders can be connected with this drive controller with the help of an interface card. This model functions perfectly in a temperature range of 5 ᵒC to 45 ᵒC. For storage/transport, the temperature range is -30 ᵒC to 85 ᵒC. Because of its quick response, the controller is often used with the MKD, MHD, and 2AD motors produced by Bosch Rexroth.
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)
