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...

Servo Drive Systems New Generation Interfaces of the Servo Drives All connections can be plugged at the front panel, the top side and, for devices with higher power, at the bottom side. LEDs and a USB interface for PC connection are provided at the front panel. Combicon connectors are available for the easy connection of: C power supply and external shunt resistor C motor C control supply voltage 24 V C protective earth PE C safety system Depending on the application, the following can be connected additionally via the Combicon connectors: C 8 digital inputs and 4 digital outputs C motor...

Servo Drive Systems New Generation 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 A signal processor controls current, speed, and power circuit. With a cycle time of only 62.5 us, 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 times on request). Safety System The wear-free electronic...

Servo Drive Systems New Generation 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: C command mode and C 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 as sub-modes: C torque mode / force mode C velocity mode C...

Servo Drive Systems New Generation Communication Industrial Ethernet or Fieldbus The Servo Drives New Generation are equipped with Industrial Ethernet or a fieldbus interface. All parameters of the servo drive can be transmitted via this interface: C control and status information C setpoints and actual values C machine data C part programs C variables The dynamically changing parameters (control and status information, rated and actual values) are transmitted cyclically via the process data channel. The other parameters are transmitted via the parameter channel. EtherCAT, Profinet, or...

Servo Drive Systems New Generation Commissioning and Software The servo drives are delivered ready for operation. For commissioning, a PC can be connected via USB interface. Alternatively, the PC can be connected via the Ethernet or fieldbus interface; for information on PC connection modules, please contact ESR. Drivers and DLL Libraries Drivers and DLL libraries are available for developing own application programs under Windows. Example programs with documented source code can be used as a basis for the development of own programs. For further information please see Data Sheet 6710.260...
