Setup for remote operation of stepper motors

[Ishizaki, Okutomi]

All signals obtained

  • We added the adapter cable for the BF LVDTs
  • Now all the sensor signals are obtained successfully at the digital system

Recovery from black out

  • Turning on the local oscillator for LVDT modulation
  • Resetting the accelerometer control (because they had got oscillated)

Setup for remote operation of stepper motors

  • 30m LAN cables for the stepper motor driver are laid
  • We set the stepper motor drivers available via the network
    • Last week we reset the settings of the stepper motor drivers for an immediate operation of the IP's motors
    • Now the two drivers are changed from real COM mode to TCP server mode
  • IP address
    • K1:STEPPER_EXV_GAS: 10.68.150.45
    • K1:STEPPER_EXV_IP: 10.68.150.46
    • More details >>> KAGRA wiki
  • Operation check hasn't done yet with the TCP server mode

Would you check the JGW serial number on these stepper motor drivers?
