Parameter function
:
Set the ratio of load inertia and motor rotor inertia
In the P5-07=0 that is, gain adjustment for manual mode should be as accurate as possible, while in the P5-07=1, 2, gain automatic and
semi-automatic adjustment mode allows some deviation.

Parameter function
:
Offline learning load inertia ratio, the output torque of the motor compared to the percentage of motor rated torque.
The greater the set value, the greater the impact will be caused by the mechanical shock, but the identification time is shorter, please according
to the appropriate value of the machine set.

2, this parameter must be set when using the semi-automatic and automatic gain adjustment mode. The system can
calculate the value of P5-00, P5-04, P5-05 related to position and speed regulator based on this parameter.

PDFF control coefficient=100, PI controller
PDFF control coefficient=1~99, PDFF controller
When using the IP controller, the running motor speed will not overshoot, but the response will be slow.
When using the PI controller, the motor running speed will be overshoot, but the response is rapid.
PDFF controller integrated IP and PI controller, in order to obtain the effect of reducing overshoot and speed up the response of the system. The
more parameter closes to 0, the stronger the IP function, and vice versa.

When P5-07=0, the gain adjustment mode is the manual mode, selecting the gain switching conditions.
When P5-07=1 and 2, the gain adjustment mode is semi-automatic and automatic mode, the function is invalid.

P5-13=0
: turn off gain switching function.
P5-13=1
