Chapter 6 Control Modes of Operation
Explanation of semi-auto tuning mode:
1. When switching mode #2 to #0, the setting value of P2-00, P2-04, P2-06, P2-25
and 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), it will
stop estimating the system inertia, save the measured load inertia value
automatically, and memorized in P1-37. However, when P2-32 is set to mode#1
or #2, the servo drive will continuously perform the adjustment for a period of time.
3. When the value of the system inertia becomes over high, the display of P2-33 will
show 0 and the servo drive will start to adjust the load inertia value continuously.
Manual Mode
When Tuning Mode Settings of P2-32 is set to 0, the users can define the proportional
speed loop gain (P2-04), speed integral gain (P2-06) feed forward gain (P2-07) and
ratio of load inertia to servo motor Inertia (1-37). Please refer to the following
description:

Proportional
responsiveness.

Integral gain: Adjust this gain can enhance the low-frequency stiffness of speed
loop and eliminate the steady error. Also, reduce the value of phase margin.
Over high integral gain will result in the unstable servo system.

Feed forward gain: Adjust this gain can decrease the phase delay error

This parameter is used to set the speed loop gain. When the value of proportional
speed loop gain is increased, it can expedite speed loop response. However, if the
setting value is over high, it may generate vibration or noise.
