6.6.6 Reverting to Mfr’s Value
When there is disorder with parameters and mfr’s value need to restored, set So-49=1.

The procedure is that set So-49=1 and holding prees SET key for 0.5s, “00000” is displayed. After 5
seconds, all parameters revert to mfr’s value automatically.
6.6.7 Motor Protection Function
(1) Motor Overload Protection
When there is output for servo motor, output current continuously generates heat, and releases heat into
surroungdings environment, when the generated heat goes over than released heat, the rising temperature
of motor is so high that make the motor excitation-loss and damage, and therefore, servo drive provides
motor overlaod protection function to prevent the damage from excessive temperature.
Set motor overload protection (So-37) to adjust the time of motor overload fault (AL-06). Generaly,
So-37 remains default value, but if the following situation happens, So-37 can be modified according to
motor actual heat situation:
●The occasion of higher operating ambient temperature for servo motro;
●The occasion that servo motor runs circularly, one-time motion period is short and frequent
switching;
