Cause of error
Calculate the regenerative
energy, and connect an exter-
nal Regeneration Resistor with
the required regeneration
absorption capacity.
Set Pn600 correctly.
Change the main-circuit power
supply voltage to within toler-
ance range.
Change the main circuit power
supply voltage to within toler-
ance range.
Replace the Servo Driver.
Deceleration time is too long.
Calculate the regenerative
energy, and connect an exter-

Reduce main circuit power
supply voltage to within toler-

Add a counterbalance to the
machinery to lower gravita-
tional torque.
Slow the descent speed.
