How to fix PI Controller communication issues?
- J
  James McleanAug 1, 2025
  If you're having trouble communicating with the PI Controller, here are a few things to check: * Ensure you are using the correct communication cable and test it on another system if possible. * Allow the E-727 to fully power on (about 20 seconds, Power LED continuously lit) before establishing communication. * Verify the interface configuration (port, baud rate for RS-232; IP address, IP mask, network settings for TCP/IP; ensure no network restrictions). * Close any other programs that might be accessing the interface. * Test with other software using the '*IDN?' or 'HLP?' command, ending with an LF (line feed). * For E-727 models with EtherCAT, ensure TCP/IP and USB interfaces are enabled after leaving the OPERATIONAL EtherCAT state.

How to stop unintentional motion of PI Controller stage?
- R
  Ronald CarlsonAug 13, 2025
  To prevent a PI Controller stage from moving unintentionally: * Check the Power Up AutoZero Enable parameter (ID 0x07000802) and adjust it if necessary. * See if a macro is specified as the start-up macro and cancel the selection of the start-up macro if necessary.
