  • Page 19: P0835

    If, for instance, one wants to read from the SCA06 servo drive the motor current in Amps, one must program the value 3 in one of these parameters, because the parameter P0003 is the one that contains this information.

  • Page 20: P0849 - Update Ethernet Configuration

    It allows you to force a reset of the Ethernet interface, to update the settings made in the device parameters. When setting this parameter to “1”, the Ethernet interface is restarted, resulting in loss of communication during this process. After the process is complete, the parameter switch automatically to “0”. SCA06 | 20...
