AMP8000 distributed servo drive

The AMP8620 supply module and the AMP8805 distribution module are now also available with an extended voltage range for the AMP8000 distributed servo drive system from Beckhoff. There is also an additional option for controlling the holding brake for the AMP80xx distributed servo drive.

The AMP8620-2005-0x10 supply module is suitable for single-phase or three-phase voltage connection at 1 x 120…240 V AC and up to 8 A DC link output current or at 3 x 200…480 V AC and a maximum of 20 A DC link output current. The AMP8805-1010-0000 distribution module, which matches all AMP8620 supply modules, now offers an input voltage range of 155 to 848 V DC. The AMP80xx-xxx2 distributed servo drive is equipped with a holding brake and an M8 connection for manual control. This allows the holding brake to be controlled during mechanical installation or for service purposes if this cannot be performed by the main controller.

The TwinSAFE SC functionality of the EL3453-0090 is identified by a yellow stripe on the housing front panel.

Power measurement with safe power monitoring

The EL3453-0090 EtherCAT power measurement terminal has voltage inputs for direct monitoring of powerful generators up to 690 V AC, such as those commonly used in the wind energy industry. No upstream voltage transformer is required.

TwinSAFE SC technology now also makes it easy to implement safe power monitoring.

The TwinSAFE SC technology (TwinSAFE Single Channel) facilitates the use of standard signals for safety-related tasks in any networks or fieldbuses. The EtherCAT I/Os, such as the new power measurement terminal, are expanded to include the TwinSAFE SC function, but will retain their typical signal properties and standard functionalities.

The TwinSAFE SC technology facilitates communication by means of a TwinSAFE protocol. These connections can be distinguished from the usual safe communication by means of Safety over EtherCAT. The data of the TwinSAFE SC components are transferred to the TwinSAFE Logic, where they can be used in the context of safety- relevant applications, e.g., for safe power monitoring.

The four current inputs of the EL3453-0090 power measurement terminal are electrically isolated from each other and allow the terminal to be used in all common current transformer configurations such as 2- or 3-transformer configurations with star or delta connection including neutral conductor current measurement. The grid analysis is carried out up to the 63rd harmonic and also summarized in the Power Quality Factor for simplified diagnosis. Like all measured terminal data, the harmonic content can be read via the process data. In addition to the “ExtendedRange” feature, which provides the full technical measuring range (130 % of the specified nominal measuring range), the EL3453-0090 now also offers TwinSAFE SC technology.
