7.2.13 Clearing the Option Unit Detection Alarm
The alarm A.E7 (option unit detection failure) occurs the first time that the SGDH
servo amplifier is turned ON after disconnecting an option board.
Use the following procedure to initialize parameter settings.
• Initialize the parameter settings with the servo OFF.
• After performing the procedure, cycle the power to restore all the parameters to the default settings.
• Because the parameter has been set for the SGDH connected to an option board,
Be sure to adjust the setting or initialize the parameter value (Fn005 of the auxiliary function mode) to meet
the current system needs.
