Servo Drive Systems New Generation Servo Drives Enclosure and Installation Servo Drives New Generation are compact devices for installation in control cabinets. They are available in three sizes. To avoid radiated emissions, the enclosure is made of stainless steel and aluminum. Since the enclosure is not varnished, all metal parts have best electrical contact to each other. Power Supply Unit The power supply unit is integrated. The power unit is fed directly by the mains (230 V AC or 3 × 400/480 V AC). For the control unit, a control supply voltage of 24 V has to be supplied. The power supply...

LEDs and a USB interface for PC connection are provided at the front panel. Combicon connectors are available for the easy connection of: ■ power supply and external shunt resistor ■ motor ■ control supply voltage 24 V ■ protective earth PE ■ safety system Depending on the application, the following can be connected additionally via the Combicon connectors: ■ 8 digital inputs and 4...

6 Servo Drive Systems New Generation Data Sheet 6770.250 V 1.2 Control and Monitoring Digital Control Loops All control loops for current (corresponds to torque or force), speed, and position work fully digitally. Thus, the servo drive is drift-free. All settings can be archived and reproduced via PC software SPP Windows. A signal processor controls current, speed, and power circuit. With a cycle time of only 62.5 ^s, the control algorithms ensure high dynamics and a high control quality. The position control runs in a 32 bit microcontroller and operates at a cycle time of 1 ms (shorter cycle...

Data Sheet 6770.250 V 1.2 Servo Drive Systems New Generation 7 Functions of the Servo Drives Operating Modes The Servo Drives New Generation can be used in a wide range of applications. For that, different operating modes such as torque/force mode, target position mode, or program mode can be selected via software. There are two large groups of operating modes: ■ command mode and ■ program mode (option) Command Mode In command mode, individual movements can be specified via different interfaces. In this mode, the following axis operating modes are available: ■ torque mode / force mode ■ velocity...
