Description
DKC11.1-040-7-FW by Rexroth, Indramat, Bosch is a AC servo amplifier drive controller in the DKC Series. The DKC11.1-040-7-FW features a Rated Current of 40A and a DC Bus Nominal Voltage of DC 700V. This Servo Drive has a Version of 1 and comes with Standard Firmware. Application features The drive system with the ECODRIVE drive controllers is the most costeffective solution offering the highest functionality for almost any field ofapplication in which translatory or rotary motions are to be automated. Outstanding performance data, an extensive range of functions as well asan excellent price-to-performance ratio represent the salient features ofthis drive system. Product features in terms of the technical applications are: • universal implementation • lower total costs • digital drive concept • highly dynamic operation • cost-effective direct connection to the power connection • software travel limit switch • absolute or incremental position detection • absolute or incremental position output • integrated holding brake control • increased operating safety • adjustable error response • automatic parameter matching • easy startup operation
Overview of the functions The functions of the digital, intelligent drive system are differentiated primarily according to the interface of the higher-level control. The fields ofapplication for the ECODRIVE drive controllers vary accordingly. The drive controller DKC01.1 is used as a: • servodrive with integrated position control • servodrive with analog speed interface and integrated actual positiondetection • servodrive with stepper interface. • servodrive with electronic gearbox function The drive controller DKC11.1 represents a particularly cost-effective solution. It is used as a: • servodrive with analog speed interface and integrated actual positiondetection • Up to 32 positioning blocks can be stored in the drive controller andselected over parallel inputs. The positioning block is executedautonomously. • Mechanical translatory elements such as gear ratios or feed constantsare adapted in the drive. • All position, speed, and acceleration data can be weighted independently of the axis kinematics. • A drive-internal referencing procedure is available for creating a reference dimension. • The axis can be moved with the jog function during setup operation. • The positioning speed can be influenced via the feedrate override. • Travel limit switch inputs and axis limit values which can be parameterized are available for limiting the travel range. • The drive status can be detected via status outputs. • The analog speed command value can be set to any value. • The actual position value is output either incrementally or absolutely. • Using a switching input, the drive can be shut down independent of thecommand value and stopped free of drift during active control.
Servo motor, according to the requirements of the control command, the power is amplified, transformed and regulated, so that the torque, speed and position control of the output of the drive device is very flexible and convenient.
Because of its "servo" performance, it is named as a servo motor. Its function is to convert the input voltage control signal into the angular displacement and angular velocity output on the axis drive control object. Servo motors are generally divided into two categories: DC servo motors and AC servo motors. Ac servo motor The rotor inside the AC servo motor is a permanent magnet, and the U/V/W three-phase electricity controlled by the driver forms an electromagnetic field, and the rotor rotates under the action of this magnetic field, while the encoder of the motor comes with a feedback signal to the driver, and the driver adjusts the rotor rotation Angle according to the feedback value and the target value. When the AC servo motor has no control voltage, only the pulsating magnetic field generated by the excitation winding is in the stator, and the rotor is stationary. When there is a control voltage, a rotating magnetic field is generated in the stator, the rotor rotates in the direction of the rotating magnetic field, in the case of constant load, the speed of the motor changes with the size of the control voltage, when the phase of the control voltage is opposite, the servo motor will reverse.
Dc servo motor
The working principle of DC servo motor is basically the same as that of ordinary DC motor. Electromagnetic torque is generated by the action of armature air flow and air gap flux to make the servo motor rotate. The armature control method is usually used to change the speed by changing the voltage while keeping the excitation voltage unchanged. The smaller the voltage, the lower the speed. When the voltage is zero, stop rotating. Because when the voltage is zero, the current is also zero, so the motor will not produce electromagnetic torque, neither will there be rotation phenomenon.
Dc servo motor is widely used in numerical control system, but DC servo motor also has some disadvantages: its brush and commutator are easy to wear; The maximum speed limit of the motor, the application environment limit; The structure is complicated, the manufacture is difficult and the cost is high.
