Cable requirements Information To ensure proper functionality, we recommend using cables from STOBER that are matched to the complete system. If unsuitable connection cables are used, we reserve the right to reject claims under the warranty. STOBER provides ready-made cables for the EtherCAT connection. It is also possible to use cables with the following specification: Ethernet patch cables or crossover cables meeting the CAT 5e quality level are the ideal cables.
STOBER 7 | Connection 7.4.19 X200, X201: PROFINET In order to be able to connect the drive controllers to other PROFINET nodes, an integrated switch with both X200 and X201 RJ-45 sockets is provided. The sockets are located on top of the device. The associated pin assignment and color coding correspond to the EIA/TIA-T568B standard.
SDHC cards with a storage capacity of 64 GB can be used only if they have been first reformatted to max. 32 GB. Since higher capacities increase the controller starting time, STOBER recommends the use of cards with a storage capacity from 2 to 4 GB.
STOBER 7 | Connection 7.4.22 Connecting a drive controller DANGER! Electrical voltage! Risk of fatal injury due to electric shock! ▪ Always switch off all power supply voltage before working on the devices! ▪ Note the discharge time of the DC link capacitors in the general technical data. You can only determine the absence of voltage after this time period.
