Description

Rated 4.8 with 8 reviewsTDM 1.2-100-300-W1-000 by Rexroth, Indramat, Bosch is a modular AC servo control drive unit in the TDM Series. The TDM 1.2-100-300-W1-000 features a Type Current of 100A and a Nominal DC Bus Voltage of 300V. This Servo Drive has a Model Configuration of 2 and features a Built-in Fan Cooling Style.The MAC drive is especially designed for high-accuracy servo applications in NC machine tools for metal machining and wood working, transfer lines, automation systems, as well as in production machines in the automotive industry. It is usually operated as a variable-speed drive in the position control loop of an NC.

In this case a speed set-point is fed to the drive from the NC. The MAC servo drive has the following application-specific functions: – High short-time acceleration moments – Torque reduction via I(red) input, which can be used for example when running up to a fixed stop, for reducing the load on the mechanical system coupled to the motor under specific operating conditions, for operating with controlled torque to load moving mechanical devices. – Torque-controlled drive for master/slave operation of two motors that are solidly coupled together. – Reversal of direction of rotation for same set-point polarity. – Set-point input via a differential input or two summing inputs with zero voltage reference. – Externally-adjustable drift offset via potentiometer. – Equipment „ready“ state can be output via potential-free relay contact.

– Rapid and clear diagnostics and easy troubleshooting via the front panel diagnostics and status lamps. – All adjustment parameters are set on the MOD programming module, so that the user of the servo drive does not need to carry out timeconsuming adjustments and calibration procedures. Matching of the controller to the motor type by the user is therefore generally unnecessary since the control parameters are already optimized in the factory for the usual existing coupled masses.The power supply module generates the DC link circuit voltage from the AC input voltage. From this the servo drive module generates a threephase system that is controlled according to amplitude, frequency and phase. This is applied to the MAC servo motor according to the current rotor position and the desired speed. The relationship between the controlled three-phase system and the controlled operating states of the servo motor is established according to the following criteria: Torque: The current amplitude of the three-phase system in the stator of the servo motor determines the resulting torque via the field of the permanentmagnet-excited rotor. It results from the system deviation of the speed controller. Speed: The frequency of the three-phase system determines the speed of the servo motor. The rotor’s position and frequency is derived from the signals of the rotor position encoder (BLC signals), depending on the required synchronism between the position of the magnetic field of the rotor and the position of the stator current.Direction of torque: The phase relationship between the three-phase system and the magnetic field of the rotor determines the direction of the torque and is derived from the polarity of the system deviation of the speed controller.

Control circuit signal conditioning: The speed controller compares the speed set-point and actual-value and from them generates the current set-point that is fed to the directional current controller via a limiter circuit (see Fig. 5). Depending on the rotor position (signalled via the BLC signals from the rotor position encoder), the direction of the current for the three stator windings is controlled so that the resulting current flow in the stator is at its most favourable in relation to the magnetic flux of the rotor. This relationship ensures that the torque is proportional to the motor current. The motor current is controlled by a current controller. This is linked to the directional current controller in order to control the current in the three phases so as to obtain a three-phase system having controlled amplitude, frequency and phase. The output signals of the current controller are timed in the pulse-width modulation stage and amplified via potential-free driver stages. The amplified signals used for driving the three-phase bridge constructed from six power transistors. The MAC three-phase servo motor is a permanently-excited synchronous motor that is made up of the following main sub-assemblies: – three-phase stator – permanently-excited rotor – optional electrically-released brake – optional separate axial fan for surface ventilation
