8.2.1 Motion Parameters for Phase Control
: These parameters are ignored.
( 1 ) Fixed Parameters
When the tuning or vibration suppression functions are used to perform Servo adjustments and model fol-
lowing control is enabled (i.e., when Pn140.0 = 1), the SERVOPACK cannot be properly controlled by
phase references. When using phase references, change the settings to the following values.
• Set the model-following control to disabled (Pn140.0=0).
• When using the utility functions for adjustment, select the following modes.
• Advanced Autotuning and Advanced Autotuning by References: Mode=1
• One-parameter Tuning: Tuning mode=0 or 1
