ELM7221-9016 | EtherCAT Terminal, 1-channel motion interface, servomotor, 48 V DC, 8 A, OCT, STO, TwinSAFE Logic
EtherCAT Terminals, compact drive technology
The ELM72xx-9016 servomotor EtherCAT Terminal with integrated absolute value interface offers high servo performance in a very compact design. The fast control technology, based on field-oriented current and PI speed control, supports fast and highly dynamic positioning tasks. The monitoring of numerous parameters, such as overvoltage and undervoltage, overcurrent, terminal temperature or motor load via the calculation of a I²T model, offers maximum operational reliability.
With the One Cable Technology (OCT) the encoder cable is omitted by transmitting the signals digitally via the existing motor cable. The option to read the electronic identification plates of suitable motors from the AM81xx series enables a plug-and-play solution for maximum convenience during commissioning.
The product is complemented by additional I/Os such as two digital inputs, which can be used to detect the end positions or to latch the position, and an additional output for the direct connection of a brake resistor for dissipating fed-back energy.
Special features:
- automatic reading of the electronic identification plate
- TwinSAFE STO/SS1, Integrated Logic
- pluggable connection technology
- integrated path control
The scope of delivery includes push-in connectors and a shroud for connecting the OCT motor cables.
