7.2 List of User Constants
The following table shows the numbers, names, factory settings, and other information for the user
constants.
I M P O R TA N T
• O f the user constants listed below, those that are reserved for the system are used internally by the SER-
VOPACK and cannot as a rule be accessed by the user.
• SERVOPACK behavior cannot be guaranteed if initial values for user constants reserved for the sys-
tem are changed.
• Encoder and Servomotor factory settings can only be changed once after power is turned ON.
• D o not enter speed or torque values higher than the maximum for the Servomotor.
