Chapter 7 Servo ParametersRevision June 2010 7-55P2 - 32▲ AUT2 Tuning Mode Selection Address: 0240H, 0241HDefault: 0 Related Section:Applicable Control Mode: ALL Section 5.6, Section 6.3.6Unit: N/ARange: 0 ~ 2Data Size: 16-bitDisplay Format: HexadecimalSettings:0: Manual mode1: Auto Mode [Continuous adjustment]2: Semi-Auto Mode [Non-continuous adjustment]Explanation of manual mode:1. When P2-32 is set to mode#0, the setting value of P2-00, P2-02, P2-04, P2-06,P2-07, P2-25 and P2-26 can be user-defined. When switching mode #1 or #2 to#0, the setting value of P2-00, P2-02, P2-04, P2-06, P2-07, P2-25 and P2-26 willchange to the value that measured in #1 auto-tuning mode or #2 semi-autotuning mode.Explanation of auto-tuning mode:The servo drive will continuously estimate the system inertia, save the measuredload inertia value automatically and memorized in P1-37 every 30 minutes byreferring to the frequency response settings of P2-31.1. When switching mode #1 or #2 to #0, the servo drive will continuouslyestimate the system inertia, save the measured load inertia value automaticallyand memorized in P1-37. Then, set the corresponding parameters according tothis measured load inertia value.2. When switching mode#0 or #1 to #2, enter the appropriate load inertia value inP1-37.3. When switching mode#1 to #0, the setting value of P2-00, P2-04 and P2-06 willchange to the value that measured in #1 auto-tuning mode.Explanation of semi-auto tuning mode:1. When switching mode #2 to #0, the setting value of P2-00, P2-04, P2-06, P2-25and P2-26 will change to the value that measured in #1 auto-tuning mode.2. After the system inertia becomes stable (The displau of P2-33 will show 1), itwill stop estimating the system inertia, save the measured load inertia valueautomatically, and memorized in P1-37. However, when P2-32 is set tomode#1 or #2, the servo drive will continuously perform the adjustment for aperiod of time.3. When the value of the system inertia becomes over high, the display of P2-33will show 0 and the servo drive will start to adjust the load inertia valuecontinuously.
